推荐答案

我也遇到了这个问题.以下技巧对我有用.

I also had this problem. The following trick has worked for me.

如果您将 node 和 npm 版本升级到最新版本会更好.之后，请按照以下步骤操作.

It would be better if you upgrade your node and npm versions to latest. After that please follow the below steps.

尝试从终端运行 curl registry.npmjs/package-name 以确保网络调用不会阻止对 npm 的包请求注册表.

Try running curl registry.npmjs/package-name from your terminal to make sure that network call is not blocking the package requests to npm registry.

如果你在 proxy 后面运行，那么你还必须配置 npm 来使用它，你可以使用:

If you are running behind a proxy, then you also have to configure npm to use it, and you can set it using:

npm 配置设置代理 proxyhost:proxyport

npm config set http-proxy proxyhost:proxyport

npm config set https-proxy proxyhost:proxyport
