問題描述

我已經從 github 下載了一個項目並嘗試在我的應用程序中npm install但我得到了這個錯誤結果：

> node-sass@4.9.0 install C:\Users\Admin\Desktop\New folder\flow\node_modules\node-sass
> node scripts/install.js

Hint: If github.com is not accessible in your location
      try setting a proxy via HTTP_PROXY, e.g.

      export HTTP_PROXY=http://example.com:1234

or configure npm proxy via

      npm config set proxy http://example.com:8080

由於我是新的 Angular 學習者，我無法理解錯誤信息？ 我可以在家里的其他筆記本電腦上運行該程序，但不能在我的辦公室電腦上運行？ 請幫助我知道問題出在哪里，我該如何解決？

編輯：我也試過npm install --global windows-build-tools但我得到了這個結果，似乎它停止工作了：

> windows-build-tools@5.2.2 postinstall C:\Users\Admin\AppData\Roaming\npm\node_modules\windows-build-tools

2 個解決方案

嘗試將此模塊安裝在 Windows 中。 要在 windows 10 上安裝 node-sass，您可能需要安裝 windows-build-tools

https://github.com/felixrieseberg/windows-build-tools

在終端中運行以下命令

npm install --global windows-build-tools

並嘗試npm install

@Hasani，正如您提到的，您無法在辦公室計算機上運行該項目是因為您的辦公室計算機在代理下，您應該設置代理以訪問 NPM

您的錯誤消息說要配置代理在這里

HTTP error 404 Not Found

Hint: If github.com is not accessible in your location
      try setting a proxy via HTTP_PROXY, e.g.

      export HTTP_PROXY=http://example.com:1234

or configure npm proxy via

      npm config set proxy http://example.com:8080

這就是你可以做的。

對於 HTTP

npm config set proxy http://proxy_host:port

適用於 HTTPS

如果有，則使用 https 代理地址

npm config set https-proxy https://proxy.company.com:8080

如果你有密碼和用戶名要輸入，你可以試試這個

npm config set https-proxy http://<username>:<password>@proxy<COMPANYDOMAIN.COM>.com:8080
