为什么 npm 安装 react-router-dom 不起作用？

Question

它像这样开始，但从不继续：

[..................] / rollbackFailedOptional: verb npm-session c63c949f06e27b29

然后过了一会儿，它失败了。 这是错误消息：

npm ERR! code ETIMEDOUT
npm ERR! errno ETIMEDOUT

Answer 1

此错误是由于代理设置不正确造成的。 验证网络代理设置是否正确。

否则尝试使用以下命令删除代理设置，然后重试。

$ npm 配置rm代理

$ npm 配置 rm https-proxy
