Question

我正在使用Visual Studio Code作为IDE学习Angular 2。一切都运行正常，以便执行＆＃34; npm start＆＃34;第一次。但是，如果我试图用CTRL + C打破这个过程，然后写'＆34; npm start＆＃34;再一次，我得到了错误：

npm ERR! node v6.9.1
npm ERR! npm  v4.0.2
npm ERR! code ELIFECYCLE
npm ERR! angular-quickstart@1.0.0 start: `tsc && concurrently "tsc -w" "lite-server" `
npm ERR! Exit status 2
npm ERR!
npm ERR! Failed at the angular-quickstart@1.0.0 start script 'tsc && concurrently "tsc -w" "lite-server" '.
npm ERR! Make sure you have the latest version of node.js and npm installed.
npm ERR! If you do, this is most likely a problem with the angular-quickstart package,
npm ERR! not with npm itself.
npm ERR! Tell the author that this fails on your system:
npm ERR!     tsc && concurrently "tsc -w" "lite-server"
npm ERR! You can get information on how to open an issue for this project with:
npm ERR!     npm bugs angular-quickstart
npm ERR! Or if that isn't available, you can get their info via:
npm ERR!     npm owner ls angular-quickstart
npm ERR! There is likely additional logging output above.

在我看来，它似乎没有杀死之前的过程，但不知道如何解决这个问题。

此错误在没有命令npm install之前出现。运行应用程序的步骤：

运行npm install命令（等待...）：

... added 116 packages in 16.745s
运行npm start命令：

... [1] 17.11.21 16:37:37 304 GET /node_modules/rxjs/util/isObject.js [1] 17.11.21 16:37:37 304 GET /node_modules/rxjs/util/tryCatch.js [1] 17.11.21 16:37:37 304 GET /node_modules/rxjs/util/errorObject.js [1] 17.11.21 16:37:37 304 GET /node_modules/rxjs/util/UnsubscriptionError.js
