Node.js 依赖项安装提供“证书链中的自签名证书”

Question

I am trying to install the dependency ursa package. But I get this error:

self signed certificate in certificate chain

Any idea on how to resolve this ?

I have set the correct proxy settings and was able to download the "node-horseman" dependency as well.

Any inputs will be much appreciated. Thanks in advance.

Answer 1

The workaround for this issue is to set the below as environment variable,

NODE_TLS_REJECT_UNAUTHORIZED=0

Thanks.

Try uninstalling Angular/cli first and installing node-gyp and then try reinstalling Angular cli

npm uninstall -g @angular/cli
npm install -g node-gyp
npm install -g @angular/cli

It worked perfectly
