throw err;

Error: Cannot find module 'import-local'

    at Function.Module._load (internal/modules/cjs/loader.js:520:25)

当我运行npm run start命令运行我的项目forkify时，我得到了这个。

错误:模块构建失败(来自./node_modules/babel-loader/lib/index.js):

当我使用lerna协调多个软件包时，我遇到了同样的问题。

假设您有一个这样的项目结构。

root
├── package.json
└── packages
    ├── first-project
    │   └── package.json
    └── second-project
        └── package.json

然后，必须首先在根文件夹上运行npm i，然后将npm i放入要处理的项目中，然后才能运行npm run build。
