Error: Cannot find module './router'

[Thispain]

When I try to run the project with "node app.js" I get this error message.

I took the following steps to eliminate the error message:

• I used the "npm install router" command: It didn't change the situation.
• I deleted line 50 from the app.js file: The page said "Cannot GET /" and I found 2 error messages on the browser console:
• GET http://127.0.0.1:5000/ 404 (Not Found)

Note that 'img-src' was not explicitly set, so 'default-src' is used as a fallback.

I fixed the 2nd error by running "scripts/postinstall.js", but the 1st is remained here.

Try running it with npm run dev or npm run build && npm run start

I was running it with npm run dev and:

• I get this error message on the console:

• And I get it on the website (not in broswer console):

https://nextjs.org/docs/messages/module-not-found This error occurred during the build process and can only be dismissed by fixing the error.

I was using npm install factorio-blueprint command, and it didn't change the situation, because the factorio-blueprint package have not dist folder.
