Module not found: Error: Can't resolve 'crypto'

I am getting the following list of errors when I run ng serve.

My package JSON is as follows:

Answer 1

I thought I would expand on what Tarique Ahmed wrote in his answer.

I was using an npm module that had the following line in the code:

const crypto = require('crypto');

I couldn't add:

"browser": {
  "crypto": false
}

to the package.json because the crypto package had to be part of the build.

It turns out that during the compilation process Angular seems to have decided to install the crypto-browserify package instead of crypto.

Adding the following to the tsconfig.json file instructs the build to use the crypto-browserify library every time that crypto is required. As you can see, I had the same issue for the stream package.

"paths": {
  "crypto": [
    "node_modules/crypto-browserify"
  ],
  "stream": [
    "node_modules/stream-browserify"
  ]
}
