Module build failed (from ./node_modules/@ngtools/webpack/src/index.js):

Question

I have created an application on angular 7 and ionic 4. I tried to edit app.routing.ts file, setting path and component. From then on I am getting this error below:

ERROR in ./src/app/department/department.module.ts
[ng] Module build failed (from ./node_modules/@ngtools/webpack/src/index.js):
[ng] Error: ENOENT: no such file or directory, open 'C:\Users\x\department\department.module.ts'
[ng]     at Object.openSync (fs.js:436:3)
[ng]     at Object.readFileSync (fs.js:341:35)

Answer 1

Make sure department component exist, check the templateUrl that corresponds to the file name you are referencing. You may have also modified the path unknowingly during modification of app.routing.ts file.

C:\Users\x\department\department.module.ts

Answer 2

This error occurs when your component can't be found with your app.module settings.

Follow these steps to solve your problem:

1. Check if the module.ts file exists.
2. Check the relative path.
3. The path is case sensitive (maybe the .ts file is Department).
