My Angular project is @Angular4.0.0.

Node: 6.9.5

I'm getting the following errors while trying to run npm install and ng build --prod.

npm install errors

• UNMET PEER DEPENDENCY [email protected]
• UNMET PEER DEPENDENCY [email protected]

ng build --prod error

• ERROR in scripts.0cfd151de42187092cb0.bundle.js from UglifyJs undefined

Please anyone help me to resolve this problem.?

Answer 1

It has missing peer dependencies, install the peer dependencies yourself. for example:

npm install bootstrap firebase

for your problem that should be: npm install [email protected] npm install --save [email protected]
