If you want to install Python packages and run them as a command on Linux <a target="_blank" href="https://fishshell.com/">fish-shell</a>, it gives an error: <code>"xxx command not found"</code>.
<blockquote>
The problem with Linux is that <code>pip install ...</code> drops scripts into <code>~/.local/bin</code> and this is not on the default Debian/Ubuntu <code>$PATH</code>.
</blockquote>
To fix it, just add <code>~/.local/bin</code> to your <code>$PATH</code> but on fish shell:
<pre><code class="lang-bash"># open config file
code ~/.config/fish/config.fish
</code></pre>
Edit <code>config.fish</code> file:
<pre><code class="lang-bash">set -gx PIP_HOME "/home/$USER/.local/bin"
set -gx PATH "$PIP_HOME" $PATH
</code></pre>
Since <code>$USER</code> and <code>$PATH</code> is global variable, so we do not need to define them.
Restart a fish shell session and try to run Python packages again!

If you want to install Python packages and run them as a command on Linux [fish-shell](https://fishshell.com/), it gives an error: `"xxx command not found"`.

> The problem with Linux is that `pip install ...` drops scripts into `~/.local/bin` and this is not on the default Debian/Ubuntu `$PATH`.

To fix it, just add `~/.local/bin` to your `$PATH` but on fish shell:

```bash
# open config file
code ~/.config/fish/config.fish
```

Edit `config.fish` file:

```bash
set -gx PIP_HOME "/home/$USER/.local/bin"
set -gx PATH "$PIP_HOME" $PATH
```

Since `$USER` and `$PATH` is global variable, so we do not need to define them.

Restart a fish shell session and try to run Python packages again!
