Allow (un)installing integrations with system-wide uv installations

[schustmi]

Describe changes

Previously we checked whether uv is installed in the active python environment which failed if uv was installed globally using different package managers or manually installing it.

Pre-requisites

Please ensure you have done the following:

• I have read the CONTRIBUTING.md document.
• I have added tests to cover my changes.
• I have based my new branch on develop and the open PR is targeting develop. If your branch wasn't based on develop read Contribution guide on rebasing branch to develop.
• IMPORTANT: I made sure that my changes are reflected properly in the following resources:
  • ZenML Docs
  • Dashboard: Needs to be communicated to the frontend team.
  • Templates: Might need adjustments (that are not reflected in the template tests) in case of non-breaking changes and deprecations.
  • Projects: Depending on the version dependencies, different projects might get affected.

Types of changes

• Bug fix (non-breaking change which fixes an issue)
• New feature (non-breaking change which adds functionality)
• Breaking change (fix or feature that would cause existing functionality to change)
• Other (add details above)

🪧 Tips

Chat

There are 3 ways to chat with CodeRabbit:

• Review comments: Directly reply to a review comment made by CodeRabbit. Example:
  • I pushed a fix in commit <commit_id>, please review it.
  • Generate unit testing code for this file.
  • Open a follow-up GitHub issue for this discussion.
• Files and specific lines of code (under the "Files changed" tab): Tag @coderabbitai in a new review comment at the desired location with your query. Examples:
  • @coderabbitai generate unit testing code for this file.
  • @coderabbitai modularize this function.
• PR comments: Tag @coderabbitai in a new PR comment to ask questions about the PR branch. For the best results, please provide a very specific query, as very limited context is provided in this mode. Examples:
  • @coderabbitai gather interesting stats about this repository and render them as a table. Additionally, render a pie chart showing the language distribution in the codebase.
  • @coderabbitai read src/utils.ts and generate unit testing code.
  • @coderabbitai read the files in the src/scheduler package and generate a class diagram using mermaid and a README in the markdown format.
  • @coderabbitai help me debug CodeRabbit configuration file.

Note: Be mindful of the bot's finite context window. It's strongly recommended to break down tasks such as reading entire modules into smaller chunks. For a focused discussion, use review comments to chat about specific files and their changes, instead of using the PR comments.

I see that the is_installed_in_python_enviroment("uv") and is_uv_installed() calls behave differently. As far as I can see, one checks whether it is installed in the current environment as a Python package, and the other one checks if it is installed (even as a separate executable). While we use the first function in the utility functions above, we still use the second one in the in the cli/integration.py. Does this mean we should change the other calls as well?

[schustmi]

This is by design: is_uv_installed checks whether uv is installed. It doesn't matter whether its globally or in the active python environment.
If uv is not installed, but the user specified to install integrations using uv, we fail.

Later on in the code when actually installing integrations with uv (we've already verified that it's installed somewhere), we need to check whether it's installed globally or in the virtualenv. Depending on the outcome of that check, we run

• python -m uv pip install if uv is installed in the virtualenv. Running this command with a globally installed uv would fail, because that is not accessible as a python module.
• uv pip install ... if uv is not installed in the virtualenv but globally.

Oh I see, I missed that connection. Got it 👍
