• I have tried restarting my IDE and the issue persists. --> issue has nothing to do with the IDE
• I have read the FAQ and my problem is not listed.

• Operating System: Ubuntu 21.10

This is an issue with the installation of ESLint, so I deleted the template, as the issue has nothing to do with how ESLint is configured or works with my source code.

This is what I did:

I have a Vue 2 project that was set up using vue-cli a couple of days ago. It had all ESLint stuff configured and it worked well enough to be useful (I'm not gonna rant about how messed up the whole process of setting up ESLint with Vue & VSCode is).

Today I tried to install a totally unrelated package via npm install and got this:

npm ERR! code ERESOLVE
npm ERR! ERESOLVE could not resolve

no, it really doesn't have anything to do with this package that I tried to install. I tried it again with some other packages with the same outcome

This is what I tried to fix it:

As vue-cli doesn't seem to have a remove command, I deleted all packages that were mentioned in this error log as well as everything else that was related to eslint from my package.json, removed package-lock.json and the node_modules directory. Then I ran npm install (which ran through without an error) and vue-cli add @vue/cli-plugin-eslint (as recommended in the Vue docs). During the installation process I selected "Standard" config. The installation ran though without any errors. Except for an "duplicate key" error because I did not delete my .eslintrc.js before, which I resolved manually.

ESLint works as good (or bad) as before. But the above error persists: whenever I try to install anything else via npm install, the peer dependency error about ESLint is thrown.

As a workaround for installing new packages, I remove everything related to ESLint, install the package, and then add it via vue add again.

Please let me know which additional info you need to help me fix this problem.
