Failed to parse source map

[JEMasonMedia]

For whatever reason, I am getting the below parse warning. It has nothing to do with my code as it only appears when I "import MDEditor from '@uiw/react-md-editor'" The library still seems to work fine, but I am not sure what to do about these major warnings.

Some popular packages do not provide sourcemap files, which is normal, and you can configure to ignore warnings for these packages. @JEMasonMedia

https://webpack.js.org/configuration/other-options/#ignorewarnings

I must be missing something. I just installed the library and set up the config file, but nothing changed once I restarted the app. I used create-react-app to bootstrap my app. Could you possibly provide a little more info please?

[jaywcjlove]

@JEMasonMedia I don't know why you have this error, I can't reproduce your error.

[JEMasonMedia]

How to reproduce:

npx create-react-app .
npm i @uiw/react-md-editor

import the library into App.js:
import MDEditor from '@uiw/react-md-editor'

npm start

Those warnings will appear in the console.

I reproduced this problem.

• sourceMap source file does not exist kktjs/kkt#325

I've been using my own tools. This issue was ignored.

"scripts": {
-  "start": "react-scripts start",
+  "start": "GENERATE_SOURCEMAP=false react-scripts start",
  "build": "react-scripts build",
  "test": "react-scripts test",
  "eject": "react-scripts eject"
},

@JEMasonMedia

[jaywcjlove]

It was fixed by adding GENERATE_SOURCEMAP=false to the .env file.

@JEMasonMedia

[JEMasonMedia]

'GENERATE_SOURCEMAP' is not recognized as an internal or external command,
operable program or batch file.

.env?

[JEMasonMedia]

"scripts": {
"start": "GENERATE_SOURCEMAP=false react-scripts start",
"build": "react-scripts build",
"test": "react-scripts test",
"eject": "react-scripts eject"
},

Finally googled what you were saying and got the .env workaround to work. Thank you for helping me out!

[jaywcjlove]

If you are running on Windows, you need to use the compatible tool cross-env

npm install --save-dev cross-env

"start": "cross-env GENERATE_SOURCEMAP=false react-scripts start",

@JEMasonMedia Of course, the way to use .evn is not needed.

[JEMasonMedia]

The .env worked on its own in windows 11. Thank you very much for your help.
