Am i doing anything wrong?
Answers:
The explanation is in your logs:
Could not fetch URL https://pypi.python.org/simple/yolk/: HTTP Error 503: Service Unavailable
Notice the HTTP Error 503: Service Unavailable. It seems the site was down when you were trying to do this.
It’s good to know that HTTP 5xx errors are server side errors, so you can know the problem was not in your local network but in the remote network.
It means try again later 😉 (and cross fingers…) (It works for me now btw.)
pip has mirror support
pip --use-mirrors install yolk
As of version 1.5, this option will be removed:
1.5 (unreleased)
BACKWARD INCOMPATIBLE pip no longer supports the –use-mirrors, -M,
and –mirrors flags. The mirroring support has been removed. In order
to use a mirror specify it as the primary index with -i or
–index-url, or as an additional index with –extra-index-url. (Pull #1098, CVE-2013-5123)
BACKWARD INCOMPATIBLE pip no longer will scrape insecure external urls
by default nor will it install externally hosted files by default.
Users may opt into installing externally hosted or insecure files or
urls using –allow-external PROJECT and –allow-insecure PROJECT.
(Pull #1055)
Added colors to the logging output in order to draw attention to
important warnings and errors. (Pull #1109)
Added warnings when using an insecure index, find-link, or dependency
link. (Pull #1121)
It’s because in the pip configuration the index-url parameter should point to the new pypi url. Change the file in ~/.pip/pip.conf or if you are running pip as root, in: /root/.pip/pip.conf.
Probably you have this:
[global]
index-url=http://f.pypi.python.org/simple
You shoudl change it for this:
[global]
index-url=https://pypi.python.org/pypi/
And then all should work as before.
I hope it helps you.
I had a similar problem with pip and easy_install:
Cannot fetch index base URL https://pypi.python.org/simple/
As suggested in the referenced blog post, there must be an issue with some older versions of OpenSSL being incompatible with pip 1.3.1.
Installing pip-1.2.1 is a working workaround.
[Edit]:
This definitely happens in RHEL/CentOS 4 distros

If you’ve tried installing a package with pip recently, you may have encountered this error:

This seems to be an issue with an old version of OpenSSL being incompatible with pip 1.3.1. If you’re using a non-stock Python distribution (notably EPD 7.3), you’re very likely to have a setup that isn’t going to work with pip 1.3.1 without a shitload of work.
The easy workaround for now, is to install pip 1.2.1, which does not require SSL:
curl -O https://pypi.python.org/packages/source/p/pip/pip-1.2.1.tar.gz
tar xvfz pip-1.2.1.tar.gz
cd pip-1.2.1
python setup.py install
If you are using EPD, and you’re not using it for a class where things might break, you may want to consider installing the new incarnation: Enthought Canopy. I know they were aware of the issues caused by the previous version of OpenSSL, and would imagine they are using a new version now that should play nicely with pip 1.3.1.
I used to use the easy_install pip==1.2.1 workaround but I randomly found that if you’re having this bug, you probably installed a 32bit version of python on a 64bit machine.
In short : If you install a 64bit version of it by installing it from the source and then build your virtualenv upon it, you wont have that pip bug anymore.
This problem is most-likely caused by DNS setup: server cannot resolve the Domain Name, so cannot download the package.
Solution:
sudo nano /etc/network/interface
add a line: dns-nameservers 8.8.8.8
save file and exit
sudo ifdown eth0 && sudo ifup eth0
Then pip install should be working now.
Your system clock is likely set in the past.Check the time using the date command and set it right
I had the same issue with pip 1.5.6.
I just deleted the ~/.pip folder and it worked like a charm.
rm -r ~/.pip/
I had this error message occur as I had set a Windows Environment Variable to an invalid certificate file.
Check if you have a CURL_CA_BUNDLE variable by typing SET at the command prompt.
You can override it for the current session with SET CURL_CA_BUNDLE=
The pip.log contained the following:
Getting page https://pypi.python.org/simple/pip/
Could not fetch URL https://pypi.python.org/simple/pip/: connection error: [Errno 185090050] _ssl.c:340: error:0B084002:x509 certificate routines:X509_load_cert_crl_file:system lib
This has happened to my because of proxy-authntication, so I did this to resolve it
export http_proxy=http://uname:[email protected]:8080
export https_proxy=http://uname:[email protected]:8080
export ftp_proxy=http://uname:[email protected]:8080
For me it worked a simple sudo pip -I install <package>.
As man pip states, -I ignores installed packages, forcing reinstall instead.
On Virtualenv try editing the pip file, like so:
vi <your_virtualenv_folder>/bin/pip
look at the first line and check if it corresponds to the project folder, if not just change it.
#!/<your_path>/<project_folder>/<your_virtualenv_folder>/bin/python
I faced the same issue and this error is because of ‘Proxy Setting’. The syntax below helped me in resolving it successfully:
sudo pip --proxy=http://username:password@proxyURL:portNumber install yolk
In my case the https port (443) wasn’t open so my firewall blocked all traffic and pip couldn’t download the packages.
I had that problem too, after I tried to reset my network settings. it solves problem.
