推荐答案

tslib 依赖项似乎存在问题.您可以在此处找到更多信息:

There seems to be an issue with the tslib dependency. You can find more info here:

https://github.com/typeorm/typeorm/issues/6054

但是启动项目的临时解决方案是将 tslint@1.11.2 添加为依赖项(yarn add tslib@1.11.2)并将其添加到 package.json

But a temporary solution to start your project is to add tslint@1.11.2 as a dependency (yarn add tslib@1.11.2) and to add this to your package.json

 "resolutions": {
   "tslib": "1.11.2" 
 }
