Failed to load plugin 'import' declared in '--config » eslint-config-standard': Cannot find module 'eslint'

Should I install eslint? Couldn't find this information in the readme.

Thanks!

Hi, @marcospgp. Thank you for using Standard. To begin helping you, I'd like more information. Could you please submit a new issue with all of the issue template filled in? For our convenience, I'll close this one.

[marcospgp]

@mightyiam I'm sorry, I don't have the time right now. I just installed standard so it's the latest version. Ran on VSCode on Windows. Standard is the only project dependency.

[mightyiam]

Could you please run npm --version and node --version and paste the results here?

[marcospgp]

For sure!

$ npm --version
6.11.3

$ node --version
v10.16.0

[mightyiam]

How are you running standard, please? Is it via the command line in VSCode or via some extension?

[marcospgp]

I tried both with the integrated command line in VSCode (bash) and through the VSCode extension, both show the same error.

[mightyiam]

Could you please paste the result of the npm ls eslint command?

I have this consistently failing on Travis CI! 😄

I wonder if the problem is that eslint isn't getting hoisted up, and thus the other modules can't find it? Since it's only required by standard:

$ npm ls eslint          
albatross@1.1.0 /Users/linus/coding/node-albatross
└─┬ standard@14.3.1
  └── eslint@6.4.0 

[LinusU]

Hmm, maybe this is related?

This @npmjs bug randomly makes ESLint installation fail when a package which has a name alphabetically before 'eslint' depends on an older version of 'acorn' eslint/espree#393 …

Not exactly the same though? 🤔

[LinusU]

This makes it seem like npm is simply not installing eslint package though 🤔

[mightyiam]

@LinusU, if you have a local installation where this is occurring, could you please type in npm ls eslint to see if and where it is I stalled?

[LinusU]

Unfortunately, I haven't been able to reproduce this locally yet. Hopefully I can take some time soon to reproduce this inside an Ubuntu Docker container ☺️

[LinusU]

This seems to be fixed with all the latest versions now.

@marcospgp can you try and trash your node_modules/ and package-lock.json, then install again and see if it works? Happy to re-open if you are still having problems!

[AndyOGo]

I just got the same error, turns out standard was upgraded in package.json, but a local package-lock.json (but wasn't commited and in gitignore file), caused it that another version was used...

So I deleted the package-lock file and reinstalled everything. Hope it helps someone.

[mightyiam]

Thank you for the tip, @AndyOGo .

[prateekrastogi]

@AndyOGo Worked pretty well for me too

I have the same error but only when I want to use it with VSCode. The ESLint tab shows this:

[Info  - 10:30:15] ESLint server stopped.
[Info  - 10:30:15] ESLint server running in node v12.8.1
[Info  - 10:30:15] ESLint server is running.
[Info  - 10:30:18] ESLint library loaded from: <path>\root\node_modules\eslint\lib\api.js
[Error - 10:30:19] 
Failed to load plugin 'import' declared in '<path>\root\.eslintrc.js » eslint-config-standard': Cannot find module 'eslint-plugin-import'
Require stack:
- <path>\__placeholder__.js
Happened while validating <path>\root\.eslintrc.js
This can happen for a couple of reasons:
1. The plugin name is spelled incorrectly in an ESLint configuration file (e.g. .eslintrc).
2. If ESLint is installed globally, then make sure 'eslint-plugin-import' is installed globally as well.
3. If ESLint is installed locally, then 'eslint-plugin-import' isn't installed correctly.

Consider running eslint --debug <path>\root\.eslintrc.js from a terminal to obtain a trace about the configuration files used.

The require stack is a bit strange because it starts from the project root and not from the eslint root.

[Fuzzyma]

Ok for VSCode try this solution in case your eslint root is not your project root: microsoft/vscode-eslint#196

[charleycodes]

@AndyOGo I was having a similar problem - deleted the yarn.lock file and re-ran yarn - the error is gone!

[Gris229]

@charleycodes you mean re-ran yarn install ?
