Angular2 QuickStart npm start 在第二天不起作用

Question

我试过了Angular2 QuickStart。为了执行这个，我使用了 npm start。第一次尝试它工作正常。但是在第二天，当我尝试使用 npm start 运行时，它会抛出这样的错误：

0 info it worked if it ends with ok

21 error Tell the author that this fails on your system:
21 error     npm run build
21 error You can get information on how to open an issue for this project with:
21 error     npm bugs angular-quickstart
21 error Or if that isn't available, you can get their info via:
21 error     npm owner ls angular-quickstart
21 error There is likely additional logging output above.
22 verbose exit [ 1, true ]

我该如何解决这个问题？

Answer 1

在您的 QuickStart 目录中打开 2 cmd windows。

Window #1:

npm run build:watch

那么，

Window#2:

npm run serve

然后它将在浏览器中打开并按预期工作。
