運行 npm i 時出錯（退出代碼 1）

Question

我在我的機器上安裝了Cordova和Ionic ，然后通過輸入ionic start demo blank創建了一個空白的測試應用程序，但是我遇到了一個錯誤並且無法處理它。

顯示的結果是這樣的：

ng directory .\demo - done!
    ading and extracting blank starter - done!

我在此鏈接上看到了相同的錯誤[錯誤] 運行 npm install 時發生錯誤（退出代碼 1）：但我不明白為什么我收到此代理錯誤並且不知道如何解決它。

Answer 1

我認為你在代理后面工作。 或者 node-sass 存儲庫不可用，因此您可以手動下載它：

npm install node-sass

如果你仍然有錯誤，那么你肯定在代理后面工作，你應該根據你的操作系統配置它。

編輯：

我只是運行命令&一切都很好。 該應用程序運行沒有問題。 我認為您對nodeJs或 npm 版本或 ionic CLI 有問題。 嘗試下載最新的nodeJs並嘗試使用以下命令更新npm ：

npm install npm@latest

我的配置是：

cli包：

    @ionic/cli-plugin-proxy : 1.5.6
    @ionic/cli-utils        : 1.19.0
    ionic (Ionic CLI)       : 3.19.0

System:

    Node : v6.11.5
    npm  : 3.10.10 
    OS   : Linux 4.4
