Create react app Error: Cannot find module './locale'

Question

I bootstrapped my application with create-react-app and when I run my app it compiles with warnings and it throws errors on the browser.

Error while compiling

./node_modules/rc-picker/node_modules/moment/src/lib/locale/locales.js
Module not found: Can't resolve './locale' in '/Users/macbook/Desktop/projects/pizza/Yummi-fend/node_modules/rc-picker/node_modules/moment/src/lib/locale'

Error on browser

I have tried researching and its an error originating from moment-js yet I'm not using that module and it is also not installed.

What could be the problem?

If you are not using moment, then run yarn remove moment or npm uninstall moment — Ibraheem Ahmed

@Redline Thanks. I have tried this and it hasn't worked for me — Kinara Nyakaru

@KinaraNyakaru Try this. Remove node-modules folder, I mean delete it and then do an npm install, See if it works — Imran Rafiq Rather

The reason this happens is because moment has released the new version from 2.24.0 to 2.25.0

Perform the following Steps to solve this issue :

Step 1: change the versions (In your case just add the "moment":"2.24.0" to your dependencies in your package.json since I don't see it present in your package.json)

"moment": "2.24.0",
"moment-timezone": "^0.5.28",

Step 2: If you are using yarn please add resolutions in your package.json file like this

"dependencies" {
"moment": "2.24.0",
"moment-timezone": "^0.5.28"
},
"resolutions": {
"moment": "2.24.0"
},

It seems like the version 2.25.2 was addressing this issue. So a downgrade to 2.24.0 is not required anymore.

@Matt Weber : So far downgrade has worked for lots of lots of developers. On 4th May 2.25.2 version has come up, still with pretty less downloads. nuget.org/packages/Moment.js

Change in package.json :

"moment": "2.25.1",

to

"moment": "2.24.0",

then run on terminal: npm install

Moment Released new version that breaks application,

as in your case there is no moment in package.json, if you simply add this to your package

moment: "2.24.0"

and run npm install it will add this moment package and resolve your issue,

otherwise you can try this cammand

npm install --save --save-exact [email protected]

it will automatically add this package to your package.json with this specific version

i hope this works for you

New moment 2.25.x versions have been released and the latest version should fix this issue.

It seems like the version 2.25.2 was addressing this issue. So a downgrade to 2.24.0 is not required anymore.
