推荐答案

确保在升级到 angular 9 后清理您的工作区并重新安装所有包/依赖项.它实际上解决了我的大部分错误.

Make sure to clean your workspace after upgrading to angular 9 and reinstall all packages/dependencies. It actually resolved most of my errors.

通过删除 node_modules 文件夹、package_lock.json 并通过 npm install 重新安装所有包来清理工作区解决了大部分问题

Cleaning workspace by deleting node_modules folder, package_lock.json and reinstalling all packages by npm install resolved most of the issues

  • 删除您的node_modules文件夹
  • 删除package_lock.json
  • 使用 npm install
  • 删除后重新安装软件包
  • Delete your node_modules folder
  • Delete package_lock.json
  • Reinstall packages after deleteing with npm install
