when I using this command to add eslint(@vue/cli 4.5.15):

vue add eslint

shows error like this:

error An unexpected error occurred: "Commit hash required".
 ERROR  command failed: yarn add @vue/cli-plugin-eslint@~4.5.0 -D

what should I do to fix this problem? I already have tried to remove the lock file but still did not fix this problem. the node version is v16.13.2.

This usually happens when a you use npm install on a yarn project, then yarn install when you realize npm didn't work. Somehow yarn.lock gets corrupted. Here is what I do:

rm package-lock.json
rm yarn.lock
git checkout <old-hash> yarn.lock

For me I did the following and it works:

$ rm package-lock.json    # remove the package-lock.json file

$ yarn install  # install successfully and update the yarn.lock file
