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 com

Answer 1

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"
},

Change in package.json :

"moment": "2.25.1",

to

"moment": "2.24.0",

then run on terminal: npm install

Answer 3

Just follow these steps:-

step 1: npm install --save-dev npm-force-resolutions

step 2: add in package.json

"resolutions": {
    "moment": "2.24.0"
 }

step 3: add in scripts in package.json

"preinstall": "npx npm-force-resolutions"

step 4: npm install

Answer 4

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 moment@2.24.0

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

i hope this works for you

Answer 5

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.
