Install and Use pipx in Linux
|
|
======
|
|
|
|
Pip is a popular tool for installing Python packages and modules from [Python Package Index][1].
|
|
|
|
However, in recent distribution versions, pip users are encountering an [externally-managed-environment error][2].
|
|
|
|
![error: externally-managed-environment][3]
|
|
|
|
That's a 'feature' added to avoid conflicts between Python packages installed via [Pip][4] and the native package manager. Python wants you to use separate virtual environments instead of installing the package at the global level via Pip.
|
|
|
|
**This is where pipx comes into the picture**. It creates a new virtual environment for each application you install and then creates links to local binary in the /bin at the global level. All this is automatic. It saves time and effort for you.
|
|
|
|
Let's see how to install and use Pipx on Ubuntu and other Linux distributions.
|
|
|
|
### Install pipx on Ubuntu and other Linux
|
|
|
|
The installation is straightforward and can be installed using the following command on Ubuntu and Debian:
|
|
|
|
```
|
|
sudo apt update && sudo apt install pipx
|
|
```
|
|
|
|
For other distributions, please use your package manager and install it.
|
|
|
|
Once you are done with the installation, [add it to the $PATH][5] so it can be accessed from everywhere:
|
|
|
|
```
|
|
pipx ensurepath
|
|
```
|
|
|
|
![install pipx in ubuntu][6]
|
|
|
|
**Close the terminal and start it again**. That's it! Now, let's have a look at how to use it.
|
|
|
|
### Using pipx
|
|
|
|
What is the primary use of a package manager? Package installation, updation, and removal.
|
|
|
|
Let me show how you can do the following with pipx:
|
|
|
|
- Search packages
|
|
- Package installation
|
|
- Upgradation
|
|
- Package removal
|
|
|
|
Let's start with the installation.
|
|
|
|
#### How to install packages using pipx
|
|
|
|
To install packages using pipx, you'd have to follow a simple command syntax:
|
|
|
|
```
|
|
pipx install <package_name>
|
|
```
|
|
|
|
For example, here, I installed a very useful program Cowsay:
|
|
|
|
```
|
|
pipx install cowsay
|
|
```
|
|
|
|

|
|
|
|
Similarly, if you want to install a specific version of the package, you'd have to insert the version number followed by `==` as shown:
|
|
|
|
```
|
|
pipx install package==version
|
|
```
|
|
|
|
For example, here, I installed numpy version 1.24.1:
|
|
|
|
```
|
|
pipx install numpy==1.24.1
|
|
```
|
|
|
|

|
|
|
#### How to search packages
|
|
|
|
The pipx utility does not have a search feature (because of limited API use of PyPI) but that doesn't mean you can't search Python packages.
|
|
|
|
To search packages, you'd have to install `pypisearch`:
|
|
|
|
```
|
|
pipx install pypisearch
|
|
```
|
|
|
|
Once you do that, you can search the packages using the `pypisearch` command:
|
|
|
|
```
|
|
pypisearch python_package_name
|
|
```
|
|
|
|
Here, I searched for neofetch:
|
|
|
|

|
|
|
|
#### How to upgrade packages using pipx
|
|
|
|
Like any other modern package manager, you can upgrade all packages at once or you can upgrade one package at a time.
|
|
|
|
To upgrade all the packages at once, all you have to do is execute the following command:
|
|
|
|
```
|
|
pipx upgrade-all
|
|
```
|
|
|
|
![upgrade all the python packages at once in ubuntu][10]
|
|
|
|
As you can see, it upgraded numpy to the latest version.
|
|
|
|
But if you want to upgrade a specific package, here's how you do it:
|
|
|
|
```
|
|
pipx upgrade package-name
|
|
```
|
|
|
|
Let's say I want to upgrade `cowsay` package to the latest version, then, I will be using the following:
|
|
|
|
```
|
|
pipx upgrade cowsay
|
|
```
|
|
|
|
![upgrade specific python package using pipx in ubuntu][11]
|
|
|
|
#### How to uninstall packages using pipx
|
|
|
|
To remove packages, you'd have to use the `uninstall` flag as shown:
|
|
|
|
```
|
|
pipx uninstall package_name
|
|
```
|
|
|
|
For your reference, here, I removed `numpy` from my system:
|
|
|
|
```
|
|
pipx uninstall numpy
|
|
```
|
|
|
|

|
### Pip or Pipx?
|
|
|
|
The restrictions put on Pip have limited its use by the end users. Thankfully, Pipx provides the much-needed alternative. It meets the Python guidelines of using virtual environments and, at the same time, allows installed applications to be available at the global level.
|
|
|
|
For end users, who are not Python application developers, this gives the option to use Python applications unavailable in distribution repositories.
|
|
|
|
I hope you find this tutorial helpful. Let me know if you have questions or suggestions.
