node.js - 使用 Angular2 quickstart 运行 npm start 会导致错误(lite-server？)

Question

在这里使用 Angular2 时遇到问题...出于某种原因我无法运行 lite-server 因为有...

most likely a problem with the angular-quickstart package

当我运行 npm start 时，我得到:

> angular-quickstart@1.0.0 start C:\xampp\htdocs\js\angular2\quickstart
> tsc && concurrently "tsc -w" "lite-server"

 Error occured when executing command: tsc -w

这东西可不简单!

Answer 1

当我尝试从 git bash 的 angular 2 站点 npm 启动 Quickstart 存储库时，我遇到了类似的问题。

我找到的解决方案是:

1.) 更新你的 SHELL 环境变量 export SHELL="/c/Program Files/Git/bin/bash"

2.) 从 Quickstart 仓库导航到 node_module/spawn-default-shell/src/get-shell.js。打开 get-shell.js 并进行以下更改:

const DETECT_SH_REGEX =/sh$/;

到

const DETECT_SH_REGEX =/sh/;
