我已经使用Typescript创建了一个NodeJS API项目。但是我无法启动它。这是我正在运行的命令
npm start
这是此命令的输出
> project1@1.0.0 prestart D:Workspace

我尝试使用
删除node_modules文件夹并清除缓存 npm cache clear
然后使用
再次安装它npm install
但无法开始？有什么问题？
问题与打字稿本身有关。这是GitHub上提出的问题
https://github.com/microsoft/typescript/issues/18301
，但是现在问题已经解决。
只需更新打字稿模块
npm update typescript --save
