Or maybe you want to try the Ranger file manager: $ python3 -m pip install ranger It's one pip command away: $ python3 -m pip install yamllint For instance, yamllint is a must-have command for anyone writing YAML files, whether for Kubernetes or Ansible or just for arbitrary config files. You can use pip for quick installs of useful Python utilities. If you install software with dnf or Flatpak, you may never have to use pip for this because those packaging systems automatically install dependencies. If the developer hasn't included a list of dependencies, it's up to you to read the documentation to learn what dependencies are required. If that file exists, you can process it with pip: $ python3 -m pip install -r requirements.txt Usually, a developer includes a list of dependencies in a file called requirements.txt in the application directory. If it were bundled with unrelated application code, it would be difficult for you to update it independently of the application. An application may not bundle support libraries along with its own code because the library isn't maintained by the same developer. When you download a script or an application written in Python, it may require specific Python libraries (or "modules" in Python terminology) to run. How well do you know Linux?

Not all Python tools necessarily cooperate with this assumption 4, but it’s a good place to start. If you make some unrecoverable error inside a project and want to erase it and restore from some known good state, removing the project directory will also erase the virtual environment. always call your virtual environment the same thingĪn advantage of always placing your virtual environment in the project directory is that it consolidates the state of the project to one location.always put your virtual environment in the same directory as the project.Where should I put my virtual environment?ĭifferent python tools have different options here, but I recommend: If you run pip freeze and see a number of Python dependencies that you don’t remember installing that have nothing to do with your project, you have probably forgotten to activate the virtual environment for your project.
