Too many issues will kill our team's development velocity, drastically.
Make sure you have checked all steps below.

Prerequisite

• Make sure your problem is not listed in the common build problems.
• Make sure no duplicated issue has already been reported in the pyenv issues. You should look for closed issues, too. (Related to pyenv install 3.5.6 failed with : ImportError: No module named 'math'. #1493)
• Make sure you are not asking us to help solving your specific issue.
  • GitHub issues is opened mainly for development purposes. If you want to ask someone to help solving your problem, go to some community site like Gitter, StackOverflow, etc.
• Make sure your problem is not derived from packaging (e.g. Homebrew).
  • Please refer to the package documentation for the installation issues, etc.
• Make sure your problem is not derived from plugins.
  • This repository is maintaining pyenv and the default python-build plugin only. Please refrain from reporting issues of other plugins here.
