npm error - Cannot find module './selenium-webdriver/lib/input'

Question

After I updated my Angular project's version from 5 to 7, I was getting a lot of vulnerabilities, to fix it - I ran all the commands that was suggested in the "npm audit" and all the vulnerabilities was fixed.

But now when I run:

ng serve

I get this error:

ERROR in node_modules/protractor/built/ptor.d.ts(33,17): error TS2307: Cannot find module './selenium-webdriver/lib/input'.

Edit

If I get in to the errors sources I can see the problem line:

// node_modules/protractor/built/ptor.d.ts
 Key: import("./selenium-webdriver/lib/input").IKey;

and if I change the line to:

 Key: import("../../selenium-webdriver/lib/input").IKey;

it's fix the error.

I guess it's a versions issue, but now remains to find out what the correct versions.

This is my package.json file:

Any ideas why?

Answer 1

To resolve this issue I had to run this command:

npm install protractor@latest --save

Answer 2

This error comes when you import from 'protactor' rather than '@angular/platform-browser' in your test cases.
