运行npm i时发生错误(退出代码1) [英] An error occurred while running npm i (exit code 1)

问题描述

我在计算机上安装了Cordova和Ionic，然后通过键入ionic start demo blank创建了一个空白测试应用程序，但是出现错误，无法处理.

I installed Cordova and Ionic on my machine, afterwards created a blank test application by typing ionic start demo blank however I got an error and couldn't handle it.

显示的结果如下:

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

I have seen about the same error on this link [ERROR] An error occurred while running npm install (exit code 1): but I don't understand why I got this proxy error and don't know how to solve it.

推荐答案

我认为您正在使用代理.要么该节点存储库不可用，要么您手动下载它:

I think you are working behind a proxy. Either that or the node-sass repository isn't available so you download it manually:

npm install node-sass

如果您遇到任何错误，那么您肯定会在代理&后面工作.您应该根据自己的操作系统进行配置.

If you sill have an error then you definitely work behind a proxy & you should configure it depending on your OS.

我只是运行命令&一切都好.该应用程序运行没有问题.我认为您在使用nodeJs或npm版本或ionic CLI时遇到问题.尝试下载最新的nodeJs&尝试使用以下命令更新npm:

I just run the command & everything is fine. The app runs without a problem. I think you have an issue with nodeJs or npm version or ionic CLI. Try downloading the latest nodeJs & try updating npm with the following command:

npm install npm@latest

我的配置是:

cli软件包:

    @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
