如何配置节点实时服务器？我收到 rollbackFailedOptionalerror

Question

我尝试了 Http 注册表并尝试了代理配置。

npm config rm proxy
npm config rm https-proxy

我的版本：

D:\Angular_code>node -v
v8.4.0

D:\Angular_code>npm -v
5.3.0

请问有人能解决这个问题吗？我挣扎了将近一天:(

Answer 1

尝试配置您的代理

您可以使用

npm config set proxy "http://[USERNAME]:[PASSWORD]@[HOST]:[PORT]/"
npm config set strict-ssl false

Answer 2

npm 配置设置代理 http://"username:pass@word"@proxy.xxxxxx.com:portnumber

npm config set https-proxy http://"username:pass@word"@proxy.xxxxxx.com:portnumber

npm 配置设置注册表 https://registry.npmjs.org/

npm set strict-ssl false

这对我有用...谢谢大家
