Common Issues

Here are a few common workarounds to try if you run into problems. It's preferred that you also open an issue (or at least comment on an existing issue) if you run into a problem, even if one of the workarounds below helps you.

1. Open the tap directory and query the repository:

cd $(brew --repo macaulay2/tap)
git show --summary

If the date shown is very old, in the same directory try resetting the repository:

git fetch origin
git reset --hard origin/main

2. Try reinstalling factory:

brew remove factory
brew install Macaulay2/tap/factory

3. Try rebuilding gfan and normaliz:

brew remove gfan normaliz
brew install --build-bottle gfan normaliz

4. If still no luck, try building the development version:

brew install --head M2
brew install macaulay2-common
