[dalenguyen]

It shows an error when I try to run npm test. Any ideas?

Did you add " import * as fs from 'fs';" this in your maint.ts

[dalenguyen]

@Hariskool, I just tried with the import * as fs from 'fs';. It shows the same error.

[Hariskool]

fs module is part of node's core modules. Update or reinstall your node js..

[Hariskool]

Give a look at this angular/angular-cli#10681

[brucebrit]

I encounter the same issue when i run npm test. Hariskool, u manage to resolve this issue?

[brucebrit]

The weird thing is that it only happen when i run npm test. Running the application normally dont trigger any issue
