Taro 首次创建小程序 运行报错：(node:7392) UnhandledPromiseRejectionWarning: Error: Cannot find module '@taroj...

如果你taro init myApp 项目选择的是云开发模板或者myApp目录下还有个client目录

目录

请接着往下看，若不是，可能与我遇到的问题不同。错误信息见最下面：

选择云开发模板

此时如果按照官方文档大家会在myApp目录下面使用yarn安装依赖：

安装依赖

其实当前的myApp目录下并不是我们的开发目录，需要cd到 client 目录下，然后再运行 yarn安装依赖

cd 到client目录下

安装依赖：

安装依赖

这样就是安装成功了

运行 yarn dev:weapp时，也要在client目录下哦。
