npm 错误！ FetchError：对 http://registry.npmjs.org/webpack-dev-server 的请求失败，原因：连接 ECONNREFUSED 127.0.0.1:8000

Question

我正在尝试使用npm 安装reactjs，并在无代理环境中使用我的PC。但是每当我使用npm install 命令时都会出现以下错误。我对此进行了很多搜索，但没有找到任何解决方案。请帮忙

npm install webpack webpack-dev-server --save-dev

错误是：

看起来它正在尝试连接到 localhost 而不是注册表。试试这个：

npm config set proxy null
npm config set https-proxy null
npm config set registry http://registry.npmjs.org/
