Using pip behind a proxy with CNTLM

for windows; set your proxy in command prompt as

set HTTP_PROXY=domainusername:password@myproxy:myproxyport

example:
set http_proxy=INDnamit.kewat:[email protected]:8880

I had the same issue : behind a corporate proxy with auth at work, I couldn’t have pip work, as well as Sublime Text 2 (well, it worked with custom setup of my proxy settings).
For pip (and I’ll try that on git), I solved it installing cntlm proxy.
It was very simple to configure :

1. Edit cntlm.ini
2. Edit “Username”, “Domain”, “Password” fields
3. Add a “Proxy” line, with your proxy settings : server:port
4. Make sure the line “NoProxy” integrates “localhost” (like that by default)
5. Note the default port : 3128
6. Save and that’s it.

To test that works, just launch a new command line tool, and try :

pip install django --proxy=localhost:3128

That worked for me.
Hope this will help you.

Under Windows dont forget to set

SET HTTPS_PROXY=<proxyHost>:<proxyPort>

what I needed to set for

pip install pep8

Under our security policy I may not use https with pypi, SSL-inspection rewrites certificates, it breaks the built-in security of pip for www.python.org. The man in the middle is the network-admin.

So I need to use plain http. To do so I need to override the system proxy as well as the default pypi:

bin/pip install --proxy=squidproxy:3128 -i http://www.python.org/pypi --upgrade "SQLAlchemy>=0.7.10"

With Ubuntu I could not get the proxy option to work as advertised – so the following command did not work:

sudo pip --proxy http://web-proxy.mydomain.com install somepackage

But exporting the https_proxy environment variable (note it’s https_proxy not http_proxy) did the trick:

export https_proxy=http://web-proxy.mydomain.com

Then:

sudo -E pip install somepackage

Phone as mobile hotspot/USB tethering

If I have much trouble finding a way through the corporate proxy, I connect to the web through my phone (wireless hotspot if I have wifi, USB tether if not) and do a quick pip install.

Might not work for all setups, but should get most people by in a pinch.

You can continue to use pip over HTTPS by adding your corporation’s root certificate to the cacert.pem file in your site-packages/pip folder. Then configure pip to use your proxy by adding the following lines to ~/pip/pip.conf (or ~pippip.ini if you’re on Windows):

[global]
proxy = [user:passwd@]proxy.server:port

That’s it. No need to use third party packages or give up HTTPS (of course, your network admin can still see what you’re doing).

How about just doing it locally? Most likely you are able to download from https source through your browser

1. Download your module file (mysql-connector-python-2.0.3.zip /gz…
   etc).

2. Extract it and go the extracted dir where setup.py is located
   and call:

   C:mysql-connector-python-2.0.3>python.exe setup.py install
   

For windows users: if you want to install Flask-MongoAlchemy then use the following code

pip install Flask-MongoAlchemy --proxy="http://example.com:port"**

At CentOS (actually I think all linux distros are similar) run

env|grep http_proxy

and

env|grep https_proxy

check what is the output of those commands (they should contain your proxy addresses).

If the outputs are empty or have incorrect values, modify them, for ex:

export http_proxy=http://10.1.1.1:8080
export https_proxy=http://10.1.1.1:8080

Now try to fetch and install some packages by using pip:

pip --proxy http://10.1.1.1:8080 install robotframework

and actually I have never met the case when it didn’t work. For some systems you need to be a root (sudo is not enough).

Warning, there is something very bad with the “pip search” command.
The search command do not use the proxy setting regardless of the way it’s being passed.

I was trying to figure out the problem only trying the “search” command, and found this post with detailed explanation about that bug: https://github.com/pypa/pip/issues/1104

I can confirm the bug remains with pip 1.5.6 on Debian 8 with python 2.7.9.
The “pip install” command works like a charm.

In Ubuntu 14.04 LTS

   sudo pip --proxy http://PROXYDOM:PROXYPORT install package

Cheers

It was not working for me. I had to use https at work:

pip install --proxy=https://user@mydomain:port somepackage

In order to update, add -U.

I got the error:

chris@green:~$ sudo http_proxy=http://localhost:3128 pip install django==1.8.8 
Downloading/unpacking django==1.8.8
  Cannot fetch index base URL http://pypi.python.org/simple/
  Could not find any downloads that satisfy the requirement django==1.8.8
No distributions at all found for django==1.8.8
Storing complete log in /home/chris/.pip/pip.log

(The proxy server’s port is ssh port forwarded to localhost:3128).

I had to set both http and https proxies to make it work:

chris@green:~$ sudo http_proxy=http://localhost:3128 https_proxy=http://localhost:3128 pip install django==1.8.8
Downloading/unpacking django==1.8.8

Cleaning up...

as http://pypi.python.org/simple/ redirects to https://pypi.python.org/simple but pip‘s error does not tell you.

This worked for me (on Windows via CMD):

pip install --proxy proxyserver:port requests

Set up invironment variable in Advanced System Settings.
In Command prompt it should behave like this :

C:Windowssystem32>echo %http_proxy%

http://username:passowrd@proxy:port

C:Windowssystem32>echo %https_proxy%

http://username:password@proxy:port

Later , Simply
pip install whatEver should work.

In Windows 7:

pip install --proxy DOMAINuser:password@proxyaddress:port package

i.e.:

pip install --proxy BRneo:[email protected]:8080 virtualenv

This is what works for me:

pip --proxy proxy url:port command package

I am also no expert in this but I made it work by setting the all_proxy variable in the ~/.bashrc file. To open ~/.bashrc file and edit it from a terminal run following commands,

gedit ~/.bashrc &

Add following at the end of file,

export all_proxy="http://x.y.z.w:port"

Then either open a new terminal or run following in the same terminal,

source ~/.bashrc

Just setting http_proxy and https_proxy variables aren’t enough for simple usage pip install somepackage. Though somehow sudo -E pip install somepackage works, but this have given me some problem in case I am using a local installation of Anaconda in my users’ folder.

P.S. – I am using Ubuntu 16.04.

if you want to upgrade pip by proxy, can use (for example in Windows):

python -m pip --proxy http://proxy_user:proxy_password@proxy_hostname:proxy_port insta
ll --upgrade pip

$ pip --proxy http://proxy-host:proxy-port install packagename

This is what worked for me on

I solved the problem with PIP in Windows using “Fiddler” (https://www.telerik.com/download/fiddler). After downloading and installing, do the following:

“Rules” => click “Automatically Authenticate”

Example: pip install virtualenv -proxy 127.0.0.1:8888

Just open your prompt and use.

https://github.com/pypa/pip/issues/1182 Search for “voltagex” (commented on 22 May 2015)

Open the Windows command prompt.

Set proxy environment variables.

set http_proxy=http://user:password@proxy_ip:port
set https_proxy=https://user:password@proxy_ip:port

Install Python packages using proxy in the same Windows command prompt.

pip install --proxy="user:password@proxy_ip:port" package_name

for windows go to C:/ProgramData/pip/pip.ini, and set

[global]

proxy = http://YouKnowTheRest

with your proxy details. This permanently configures the proxy for pip.

Set the following environment variable: export PIP_PROXY=http://web-proxy.mydomain.com

If you are using Linux, as root:

env https_proxy=http://$web_proxy_ip:$web_proxy_port pip install something

When you use env it exports the variable https_proxy for the current execution of the command pip install.

$web_proxy_ip is the hostname or IP of your Proxy
$web_proxy_port is the Port

I could achieve this by running:

pip install --proxy=http://user:[email protected]:3128 package==version

I’m using Python 3.7.3 inside a corporative proxy.

If you are connecting to the internet behind a proxy, there might be problem in running the some commands.

Set the environment variables for proxy configuration in the command prompt as follows:

set http_proxy=http://username:password@proxyserver:proxyport
set https_proxy=https://username:password@proxyserver:proxyport

A simpler approach might be:

1. Create a folder named “pip” in your $HOME directory.
2. Create a file named “pip.ini” (Windows) or “pip.conf” (Linux) in the directory
   created in step 1

3. Copy & paste the following lines under the pip.ini/pip.conf:

   [global]
   trusted-host = pypi.python.org
                  pypi.org
                  files.pythonhosted.org 
   

1. For PIP Installation:

ex:PORT = 9090
ex:PROXY_SERVER = stackoverflow
USERNAME:your user id
PASSWORD: your password

• sudo pip2 install PACKAGENAME --proxy https://USERNAME:PASSWORD@PROXY_SERVER:PORT/ for Python2.7

• sudo pip3 install PACKAGENAME --proxy https://USERNAME:PASSWORD@PROXY_SERVER:PORT/ for Python3.5

Example:

sudo pip2 install pandas --proxy https://USERNAME:PASSWORD@PROXY_SERVER:PORT/

2. For apt-get Installation

sudo http_proxy=http://USERNAME:PASSWORD@PROXY_SERVER:PORT/ apt-get install PACKAGENAME

Example:

sudo http_proxy=http://USERNAME:YOURPASSWORD@PROXY_SERVER:PORT/ apt-get install tensorrt

sudo http_proxy=http://USERNAME:YOURPASSWORD@PROXY_SERVER:PORT/ apt-get update

Using pip behind a work proxy with authentification, note that quotation is required for some OSes when specifing the proxy url with user and password:

pip install <module> --proxy 'http://<proxy_user>:<proxy_password>@<proxy_ip>:<proxy_port>'

Documentation: https://pip.pypa.io/en/stable/user_guide/#using-a-proxy-server

Example:

pip3 install -r requirements.txt --proxy 'http://user:[email protected]:1234'

Example:

pip install flask --proxy 'http://user:[email protected]:1234'

Proxy can also be configured manually in pip.ini.
Example:

[global]
proxy = http://user:[email protected]:1234 

Documentation: https://pip.pypa.io/en/stable/user_guide/#config-file

2022 for windows:

I know there are many answers and nearly every other question with pip and behind a proxy is refering to this question:

So in my opinion it is on the one hand the proxy thing, which is answered in the questions below.

pip install --proxy=https://<windowsuser>:<pw>@<proxy>:port package

After that you have to deal with the SSL certificates. You have to add the trusted sources. Usually they are standing in the Error message. For example: ERROR: .... host='files.pythonhosted.org' And here is my solution for installing for example Django:

pip install Django --proxy http://windowsuser:password@proxy:port --trusted-host pypi.python.org --trusted-host pypi.org --trusted-host files.pythonhosted.org
