模块构建失败无法找到从 babel\index.js 导入的包 \@babel\core\

Question

这个问题我已经纠结好几天了。我做了一些研究，但在 vain.After“ng serve”终端中总是报告：

> ./node_modules/@angular/router/fesm2020/router.mjs - Error: Module build failed (from ./node_modules/@angular-devkit/build-angular/src/babel/webpack-loader.js):
Error [ERR_MODULE_NOT_FOUND]: Cannot find package '\node_modules\@angular\compiler-cli\node_modules\@babel\core\' imported from \node_modules\@angular\compiler-cli\bundles\linker\babel\index.js
Did you mean to import @babel/core/lib/index.js?

我的 package.json 如下所示：

"devDependencies": {
"@angular-devkit/build-angular": "^13.0.2",
"@angular/cli": "^13.0.2",
"@angular/compiler-cli": "~13.0.1",
"@babel/cli": "^7.16.8",
"@babel/core": "^7.16.7",
"@babel/node": "^7.16.8",
"@babel/preset-env": "^7.16.8",
"@types/file-saver": "^2.0.3",
"@types/jasmine": "~3.8.2",
"@types/node": "^16.7.10",
"@types/xlsx": "0.0.36",
"babel-loader": "^8.2.3",
"jasmine-core": "~3.8.0",
"karma": "~6.3.4",
"karma-chrome-launcher": "~3.1.0",
"karma-coverage": "~2.0.3",
"karma-jasmine": "~4.0.1",
"karma-jasmine-html-reporter": "~1.7.0",
"typescript": "~4.4.4",
"webpack": "^5.66.0"}

我的 .babelrc 是：

{"presets": ["@babel/preset-env"]}

你能给我一些建议吗？谢谢！

我遇到了同样的问题。 node_modules 中一定有一些奇怪的缓存在进行。我不知道发生了什么，但我能够通过运行 ..

解决

rm -rf node_modules

然后

npm install

希望对你有用！
