推荐答案

在我的情况下，问题是我正在使用mac并尝试将项目转移到Windows 10计算机。要遵循的步骤：

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. 在终端中，导航到离子项目的根文件夹


2. 运行此命令： npm install @ ionic / app-scripts @ latest --save-dev


3. 运行 npm rebuild node-sass 为您当前的环境构建绑定。

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.

我不知道你的情况如何但在我的情况下，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，可能是这里的文件：

If your case is different, perhaps the documentaion here:
