vue-cli@3 没有可用于依赖类型的模块工厂：CssDependency

Question

当我使用 vue-cli@3

npm run build

系统提示生成此错误 No module factory available for dependency type: CssDependency

我搜索了很多相关的问题，但它们都是有角度的？我也尝试过

1. rm -r node_modules
2. rm 包-lock.json
3. 我的

但是还是出现这个错误，我想知道我该如何解决这个问题

这是我的错误的详细信息

Answer 1

我遇到了同样的问题，并发现它与运行npm run build命令时使用的路径的大写/小写有关。

使用 Powershell 或 cmd，我这样做了：

C:\> cd C:\git\testing
C:\git\testing> npm run build

并得到与您相同的错误。

然后我做了这个（注意大写的 GIT）：

C:\>cd C:\GIT\testing
C:\GIT\testing> npm run build

然后它起作用了。我在 Windows 10 上。
