Pipx installation script installed pip as well, but in installation logs we see:

WARNING: You are using pip version 19.2.3, however version 20.0.2 is available.
You should consider upgrading via the 'pip install --upgrade pip' command.

Upgrading pip

First of all, let's upgrade our repository info:

$ sudo eopkg up

Then you can check, if PATH is set up for pipx. Try running command:

$ pipx --version

In case PATH is set, you'll see version of pipx:

dima@edustorage ~ $ pipx --version
0.15.1.3

Setting PATH for pipx

In case PATH is not set, you will se this message:

bash: pipx: command not found

For simplicity of further work, let's set it. Normally, pipx will be installed in ~/.local/bin  :

$ ls ~/.local/bin

Is it working? Let's check:

$ cd ~/.local/bin
$ ./pipx --version

output:

Good. Pipx is working. Now let's set up PATH to run pipx by executing only "pipx" regardless the directory we're currently in.

The only thing we have to do is to add alias. Open ~/.bashrc file and add row "alias pipx='~/.local/bin/pipx'. You can use any text editor you want (nano, vim). I use vim, for example.

$ vim /.bashrc

Save the file.

And update .bashrc:

$ source ~/.bashrc

Now we can call pipx by command 'pipx' from any location in our system. For example:

$ pipx --version
