Answers:
Run
locate pip3
it should give you a list of results like this
/<path>/pip3
/<path>/pip3.x
go to /usr/local/bin to make a symbolic link to where your pip3 is located
ln -s /<path>/pip3.x /usr/local/bin/pip3
I had a similar issue. In my case, I had to uninstall and then reinstall pip3:
sudo apt-get remove python3-pip
sudo apt-get install python3-pip
Same issue on Fedora 23. I had to reinstall python3-pip to generate the proper pip3 folders in /usr/bin/.
sudo dnf reinstall python3-pip
You can use python3 -m pip as a synonym for pip3. That has saved me a couple of times.
There is no need to install virtualenv. Just create a workfolder and open your editor in it. Assuming you are using vscode,
$mkdir Directory && cd Directory
$code .
It is the best way to avoid breaking Ubuntu/linux dependencies by messing around with environments. In case anything goes wrong, you can always delete that folder and begin afresh. Otherwise, messing up with the ubuntu/linux python environments could mess up system apps/OS (including the terminal). Then you can press shift+P and type python:select interpreter. Choose any version above 3. After that you can do
$pip3 -v
It will display the pip version. You can then use it for installations as
$pip3 install Library
You can make symbolic link to you pip3:
sudo ln -s $(which pip3) /usr/bin/pip3
It helps me in RHEL 7.6
Probably pip3 is installed in /usr/local/bin/ which is not in the PATH of the sudo (root) user.
Use this instead
sudo /usr/local/bin/pip3 install virtualenv
For Kali, you must use this code after the update.
$sudo python3 get-pip.py
or if you write this, it also works but not supported anymore. So don’t use:
$sudo python get-pip.py
On Windows 10 install Python from Python.org
Once installed add these two paths to PATH env variable
C:Users<your user>AppDataLocalProgramsPythonPython38
C:Users<your user>AppDataLocalProgramsPythonPython38Scripts
Open command prompt and following command should be working
python –version
pip –version
This is the generic solution for all type of issues like Package 'xyz' has no installation candidate or command not found but is already installed:
just run this command
rmadison <package_name>
eg: rmadison python3-pip
The above command will query the apt database.
if you were not able to run the above command: sudo apt install devscripts and then run rmadison command.
