【问题描述】：
在 MEAN 课程项目中，我无法运行它，因为出现以下错误：
$ npm run start
> mean-course@0.0.0 start
> ng serve
Node packages may not be installed. Try installing with 'npm install'.
Error: Could not find the '@angular-devkit/build-angular:dev-server' builder's node package.
所以我进入 package.json 文件并在“devDependencies”下添加以下行：
"@angular-devkit/build-angular:dev-server": "15.1.6",
然后我尝试运行 npm run start 并收到以下错误，指出依赖项仍未安装：
> mean-course@0.0.0 start
> ng serve
Node packages may not be installed. Try installing with 'npm install'.
Error: Could not find the '@angular-devkit/build-angular:dev-server' builder's node package.
有人有同样的问题或知道解决方案吗？任何帮助将不胜感激谢谢！

你在 npm start 之前运行过 npm install 吗？
