Answer 1

You can use python3 -m pip as a synonym for pip3 . That has saved me a couple of times.

Answer 2

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

Answer 3

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

Answer 4

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

Answer 5

You can make symbolic link to you pip3:

sudo ln -s $(which pip3) /usr/bin/pip3

It helps me in RHEL 7.6

Answer 6

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

Answer 7

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

Answer 8

On Windows 10 install Python from Python.org Once installed add these two paths to PATH env variable C:\\Users<your user>\\AppData\\Local\\Programs\\Python\\Python38 C:\\Users<your user>\\AppData\\Local\\Programs\\Python\\Python38\\Scripts

Open command prompt and following command should be working python --version pip --version

Answer 9

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
