我在Task Run Explorer中编译时从gulp获取此错误， 这很奇怪，因为我不会改变任何事情......无论如何，我在网上搜索并找到了一些解决方案但是没有工作。
错误1
... node_modules/@angular/common/src/facade/lang.d.ts(11,17）：错误 TS2304：找不到名称＆＃39;地图＆＃39;。 node_modules/@angular/common/src/facade/lang.d.ts(12,17）：错误 TS2304：找不到名称＆＃39; Set＆＃39;。 node_modules/@angular/common/src/pipes/async_pipe.d.ts(41,38）：错误 TS2304：找不到名字＆＃39;承诺＆＃39;。 ...
这是我的tsconfig.json

如果我做第二个解决方案，我可以用旧浏览器的兼容性问题吗？
