[SOLVED] Automate creation of a pyenv through sh scripts

Issue

I'm running a project that uses pip and a requirements.txt file to install and keep track of some dependencies. I want to write some sh scripts to run, build and test the application. For starters I would like a way to check if the current folder is in a pyenv and, if not, create one to enclose the application and not mess around other people's dependencies. Also, I would like an opinion of the best way to keep track of this kind of dependencies, if the requirements.txt is a good approach and if there's a way to keep track of installed versions just like happens with node packages.

Solution

Use Pipenv. It's a better way of tracking your depencies than requirements.txt and it uses Pyenv to automatically install your project's required Python version.

From the website:

The problems that Pipenv seeks to solve are multi-faceted:

• You no longer need to use pip and virtualenv separately. They work together.
• Managing a requirements.txt file can be problematic, so Pipenv uses Pipfile and Pipfile.lock to separate abstract dependency declarations from the last tested combination.
• Hashes are used everywhere, always. Security. Automatically expose security vulnerabilities.
• Strongly encourage the use of the latest versions of dependencies to minimize security risks arising from outdated components.
• Give you insight into your dependency graph (e.g. $ pipenv graph).
• Streamline development workflow by loading .env files.

[...]

Pipenv Features

• Enables truly deterministic builds, while easily specifying only what you want.
• Generates and checks file hashes for locked dependencies.
• Automatically install required Pythons, if pyenv is available.
• Automatically finds your project home, recursively, by looking for a Pipfile.
• Automatically generates a Pipfile, if one doesn’t exist.
• Automatically creates a virtualenv in a standard location.
• Automatically adds/removes packages to a Pipfile when they are installed or uninstalled.
• Automatically loads .env files, if they exist.
