我的问题不同我安装了ionic-app-scripts 0.0.47，就像我在其他人的答案中读到的那样但是它没有工作我也尝试过
@ionic/app-scripts@latest但它不起作用我有这个错误
build dev failed: Cannot set property 'fileSystem' of null
答案 0 :(得分：1)
在package.json中安装此："@ionic/app-scripts": "1.0.0"版本的app-scripts。
此错误发生在npm update或ionic lib update之后（我想测试这些命令...... BIG MISTAKE）。
小心lib更新。
