npm - Angular 2 beta "npm run tsc"命令失败

Question

我似乎无法使用 npm run ts"命令编译我的 Typescript。我觉得有点奇怪的是我可以运行 npm start 并且它可以正常编译和运行。

日志如下:

您可能使用“npm install”安装您的依赖项。这意味着它们不在路径中。这就是为什么直接使用 tsc 命令不起作用的原因。

当使用“npm run start”时，我怀疑并发对路径做了一些事情，以便能够使用 node_modules 文件夹中的 libraires(及其 tsc 命令)。

像“$(npm bin)”这样的用法:

> $(npm bin)/tsc
