Question

我是离子新手。我想创造一个新的测试离子应用程序。我使用命令

创建了离子项目

npm install -g ionic cordova
ionic start gallery

并运行该应用。但它无法构建main.css。

我想知道为什么编译工具不起作用。那我怎么解决呢？

请帮帮我

这是控制台

Answer 1

有一个已修复的错误。运行

npm install @ionic/app-scripts@2.0.2 --save-dev

如果仍然出现此错误，请删除node module文件夹并运行

npm install

Answer 2

今天是app-scripts的错误

Ionic Framework3 missing main.css

这个问题在一小时前解决了：

“升级回最新版本的app-scripts”

https://github.com/ionic-team/ionic/issues/12442

所以，一般来说 - 只是尝试重新安装。
