I'm testing a python3 program on several computers To do that, I need to install a library of Python with pip3 .

So first, I was installing python3-pip in each computer (everyone is running Kubuntu OS). Everything was OK, and then I installed the package I needed with pip3 , and I managed to do that except for one computer.

In that computer, python3-pip was apparently installed succesfully, but when I look for the package, I get this error (the translation is homemade).

Command «pip3» was not found, maybe you wanted to say:
 The command «pip» from the package «python-pip» (universe)
pip3: command not found

EDIT

Results of dpkg -L python3-pip .

Best Answer

There are three things that'll probably fix this

In case python3-pip did not install correctly, re-install it:

This is used for debian-based distros such as ubuntu mint
```
sudo apt-get remove python3-pip; sudo apt-get install python3-pip
```
If using fedora, centos, rhel, please use.
```
sudo dnf reinstall python3-pip
```
Try using the command python3-pip instead (works on Fedora; I don't have a copy of Kubuntu to try it on).
Just a wild guess...check pip --version . There is a slight possibility that after installing python3-pip the new pip would replace the old pip (perhaps via alternatives ?)

EDIT
Now that the output of dpkg -L python3-pip has been added to the question, I can provide the answer.

The correct command name to use is: pip-3.2.
