Question

我正在新系统上设置开发环境。在我的项目文件夹中：

npm install
npm run serve

得到了：

Module build failed (from ./node_modules/babel-loader/lib/index.js):
Error: [BABEL] /Users/user/Documents/project/editor/src/main.js: Cannot find module '@babel/compat-data/corejs3-shipped-proposals'

 @ multi (webpack)-dev-server/client?http://192.168.0.105:8080/sockjs-node (webpack)/hot/dev-server.js ./src/main.js

我在node_modules / @ babel / compat-data /中签入了该模块。为什么webpack（它是webpack？）看不到？

请注意，几周前我在另一个系统上做了同样的事情，并且工作正常。我在同一新系统上也有一个vuepress项目，它也运行良好。

谢谢

Answer 1

在项目文件夹中：

rm package_lock.json
rm -r node_modules
npm install

结果是我在另一个系统上的git上有package_lock.json。删除它并起作用。

Answer 2

您可以删除生成的锁定文件（package-lock.json）然后从项目中删除节点模块。

然后再次尝试通过npm下载依赖项作为 npm安装

重新安装PC时出现“ [BABEL]找不到模块”
