Angular 4项目ng build --prod失败

Question

My Angular project is @Angular4.0.0.

Angular CLI: 1.7.4

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 bootstrap@4.0.0-alpha.6
• UNMET PEER DEPENDENCY firebase@4.13.1

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 bootstrap@4.0.0 npm install --save firebase@4.13.1
