fix(release): refresh PATH after mise up in release-plz by jdx · Pull Request #8292 · jdx/mise

jdx · 2026-02-21T18:57:42Z

Summary

mise run sets up PATH at invocation time, so when mise up upgrades tools mid-script (e.g. gh 2.87.0 -> 2.87.2), the old install paths become stale and subsequent calls fail with "No such file or directory"
Adds eval "$(mise env)" after mise up && mise lock to refresh PATH with the new tool locations

Fixes the release-plz CI failure: https://github.com/jdx/mise/actions/runs/22262068940

Test plan

Verify next release-plz run completes successfully

🤖 Generated with Claude Code

Note

Low Risk
Small change to a CI-only release script; low blast radius, with the main risk being unintended environment differences for later release steps.

Overview
Fixes the xtasks/release-plz CI release script by refreshing the environment after tool upgrades: it now runs eval "$(mise env)" after mise up/mise lock so subsequent commands use the updated tool install paths.

Summary of Changes

Hello @jdx, I'm Gemini Code Assist¹! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request resolves a critical CI failure in the release-plz workflow by ensuring that the system's PATH environment variable is correctly updated after mise upgrades tools. This prevents subsequent commands from failing due to outdated tool references, thereby stabilizing the release process.

Highlights

Fix for stale PATH in CI: Addressed an issue where mise run's PATH became stale after mise up upgraded tools, leading to 'No such file or directory' errors in the release-plz CI.
PATH refresh mechanism: Implemented eval "$(mise env)" after mise up && mise lock to ensure the PATH environment variable is refreshed with the correct, updated tool locations.

Changelog

xtasks/release-plz
- Added a command to refresh the shell's PATH environment variable after mise up.

Activity

The author identified a CI failure related to stale tool paths after mise up.
A solution involving eval "$(mise env)" was proposed and implemented.
The author plans to verify the fix by confirming the next release-plz run completes successfully.
The pull request was generated with the assistance of Claude Code.

Code Review

This pull request introduces a fix for an issue in the release-plz script where tool paths could become stale after an in-script upgrade via mise up. The change adds eval "$(mise env)" immediately after mise up and mise lock to refresh the shell's environment, particularly the PATH variable. This is the correct and idiomatic approach to ensure that subsequent commands use the newly installed tool versions. The change is clear, well-commented, and effectively resolves the described problem. I find no issues with this implementation.
