我正在运行上面的命令来安装缺少的 npm 包，它在安装 npm 时出现以下错误 node-sass@4.10.0 install F:\TPL\TFS\AdminPortal-branch-v1.0.0\Src\node_modules@angular-devkit\build-angular\node_modules\node-sass

 please let me know if any one also facing same issue i have been stuck in this error since long time

【问题讨论】：

您需要在 .npmrc 中配置正确的代理。这与代理的配置方式有关。
如何在 .npmrc 中设置代理？
您可能必须使用命令npm config set https-proxy with the proxy specified 并为 http-proxy 再运行一次。
为什么我需要设置，因为它在我的个人网络上给了我同样的错误，没有任何代理设置
我不太确定你背后的代理。但我猜您的一位开发人员可能已经遇到过这种情况。

【解决方案1】：

试试 npm install --global windows-build-tools 然后npm install

【讨论】：

我已经运行 npm install --global windows-build-tools 并给出以下错误错误！代码 ETIMEDOUT npm 错误！ errno ETIMEDOUT npm 错误！对registry.npmjs.org/windows-build-tools 的网络请求失败，原因：连接 ETIMEDOUT 93.184.216.34:8080 npm ERR！网络这是与网络连接有关的问题。 npm 错误！网络在大多数情况下，您使用代理服务器或网络设置错误。 npm 错误！网络 npm 错误！网络如果您在代理后面，请确保 npm ERR!网络“代理”配置设置正确。请参阅：'npm 帮助配置'
如果你使用的是实体网络，你应该使用 npm npm config set proxy http://:@: npm config set 设置代理https-proxy http://:@:
也许这将有助于 npm 缓存验证
检查 node-sass 是否全局安装，如果不尝试安装。
