Module not found: Error: Can't resolve 'stream' in 'C:\dev\jszip-test\node_modules\jszip\lib'

Question

I'm using jszip v3.2.1 in an angular 7 application. When I build my project (running, for example, npm start) I'm getting the following error:

ERROR in ./node_modules/jszip/lib/readable-stream-browser.js

Module not found: Error: Can't resolve 'stream' in 'C:\dev\jszip-test\node_modules\jszip\lib'

How can I solve this problem?

Answer 1

After reading this post I found out that the stream package was missing from my project.

You can install it by running the following command:

npm i stream

Answer 2

In my case, I wanted to import EventEmitter and added it accidentally from stream package instead of @angular/core package.

Wherever you import the web3 library, change your import from

import Web3 from 'web3'

to import Web3 from 'web3/dist/web3.min.js'
