10,527 PointsNPM local server won't start. I am getting an error with ESLint
Hi All,
I am on video 4 of the "Building Applications with React and Redux" series of videos. I have converted the App.js module to Scoreboard.js and I have installed all the dependencies. When I Try to start the server (npm start) I get an error (see below). It has something to do with ESLint. Thanks in advance for any help you can give me ....
Oops! Something went wrong! :(
ESLint: 7.7.0
No files matching the pattern "./src/*/.{js," were found.
Please check for typing mistakes in the pattern.

19,938 PointsHi Peter
Can you check that the file path is correct. The relative path is relative to the package.json, not to the working directory.
lint: eslint ./src/*/.{js, jsx}
So the above should have some structure like this:
src/somefolder/some-file.js
package.json
...
Try specifying the extensions separate with the below command in your script
eslint —ext .jsx,.js src/**/*
Or
eslint —ext .jsx,.js src/
If that doesn’t work can you paste in the full log so I can see more details as to what’s going wrong /Users/petermingione-macbook-home/.npm/_logs/2020-08-24T22_45_07_674Z-debug.log
Hope this helps!

19,938 PointsHmm could be a dependency or caching issue but I believe its a versioning issue. Could you do the following steps just to be sure:
-
Clean your node cache
npm cache clean --force
-
Remove your node_modules folder
rm -rf node_modules/
-
Fresh install
npm install
-
Run eslint script by itself
npm run lint
-
It looks like the error is triggering due to no files being found. Which it should as where you are at in the video, there is no files under src. If you go into your
package.json
and replace thelint
script with the following. This is exactly the same as before with the--no-error-on-unmatched-pattern
argument that will suppress the errors if nothing is found. Referenceeslint ./src/**/*.{js, jsx} --fix --no-error-on-unmatched-pattern
As for the reasoning. This is due to the difference in versions. In the video, they are using eslint 3.3.1
and you are using 7.7.0
. This was introduced in v6.x
.
Good Luck!

10,527 PointsHi Liam, THanks for the help but I am very new to npm and React. I am not sure what all of the above means ...
YOU SAY: "Can you check that the file path is correct. The relative path is relative to the package.json, not to the working directory."
ME: I am not sure where I am looking for this.
I see this in package.js:
"lint": "eslint ./src/*/.{js, jsx} --fix"
YOU: "Try specifying the extensions separate with the below command in your script"
ME: I am not sure where to do this or even what it means.
YOU: "If that doesn’t work can you paste in the full log"
ME: Where would I find the full log?
Sorry.. again I don't know much about this. Can you give me the "For Dummies" version of all of this.
