错误：找不到模块“ react-dev-utils / ignoredFiles”

Question

我将React更新到16.3.0，我的应用因Error: Cannot find module 'react-dev-utils/ignoredFiles'崩溃Error: Cannot find module 'react-dev-utils/ignoredFiles' 。 我尝试将以下命令写到控制台： npm install --save-dev react-scripts ，但没有帮助，否则我尝试从项目中删除节点模块并使用npm i重新安装它，但没有任何结果。

从package.json的依赖项：

"dependencies": {
    "autoprefixer": "7.1.2",
    "babel-core": "6.25.0",
    "babel-eslint": "7.2.3",

我假设您正在使用“ create-react-app”

我建议您删除package-lock.json然后运行npm install

在大多数情况下，更改package.json中的react-scripts版本并在此文件夹中运行npm install就足够了。

npm install --save --save-exact react-scripts@1.1.4
