Error: Cannot find module 'eslint/lib/rules/no-unused-expressions

[on3iro]

Hey,

is just installed v11 and unfortunately can't seem to get it to work at all.
Standard always throws the following error:

Error: Cannot find module 'eslint/lib/rules/no-unused-expressions'

If I manually install eslint I get a Resolve error: unable to load resolver "node"

Any idea what could cause this and how I can fix it?

Thanks in advance

Can you share the output of npm ls eslint --depth=99?

[on3iro]

If I do a fresh npm i and run npm ls eslint --depth=99 it just returns (empty)

here is my current package.json, if that helps

I also have this on a new installation (on a fresh Macbook)

npm ls eslint --depth=99
<project_name>@0.0.1 /Users/laurensbosscher/dev/app2/app
└─┬ standard@11.0.0
  └── eslint@4.18.1

@on3iro It's not good that you don't have eslint installed in your local node_modules folder. Something is seriously wrong... especially given that standard (which depends on eslint) is in your package.json. Whatever is wrong with your tree, it's not a standard issue, so I'm going to close this issue.

If I'm mistaken, or you get new info, feel free to comment or open a new issue.
