错误:找不到模块'/app/react-web/react-scripts‘

Question

我有以下两个启动脚本：

根目录中的package.json

    "start": "cd react-web && npm run postinstall && export REACT_APP_CUSTOMER_ENVIRONMENT=gianlucaherokutest320880 && npm start"

和react-web中的package.json

    "start": "node react-scripts --max_old_space_size=2560 start",

当我运行这段代码时，它给出了一个错误：

但奇怪的是，我已经安装了react-scripts。有谁有什么想法吗？

Answer 1

检查node_modules文件夹和Package-lock.json文件是否存在。

如果存在，请删除Node_modules和Package-lock.json

并运行以下命令

npm install

并这样做

npm start
