我尝试在全局范围内卸载、安装、安装，但没有解决.有什么想法吗?

I tried to unistall, install, install globally, but it didn't solve. Any ideas what's wrong?

推荐答案

就我而言，问题是我在 Mac 上工作并试图将项目转移到 Windows 10 机器上.后续步骤:

In my case the problem was that I was working on a mac and attempted to transfer the project to a windows 10 machine. Steps to follow:

1. 在您的终端中，导航到 ionic 项目的根文件夹
2. 运行这个命令:npm install @ionic/app-scripts@latest --save-dev
3. 运行 npm rebuild node-sass 为当前环境构建绑定.

1. In your terminal, navigate to the ionic project's root folder
2. Run this command: npm install @ionic/app-scripts@latest --save-dev
3. Run npm rebuild node-sass to build the binding for your current environment.

我不知道你的情况是什么，但就我而言，上述步骤有效.

I don't know what your case is but in my case, the above steps worked.

如果您的情况不同，也许这里的文档:

If your case is different, perhaps the documentaion here:
