'.' 不被识别为内部或外部命令（为 firebaseUI 运行 npm install 时）

Question

我无法在我的 firebaseUI 演示应用程序上安装 npm 包。 我在 github 上克隆了 master 分支，只是尝试运行“npm install”，但是我遇到了一个错误，我从未遇到过节点包管理器。 我得到

'.' is not recognized as an internal or external command

我也试过这将 cygwin64 并得到完全相同的结果。 下面是错误，下面是我的 package.json

firebaseui@3.3.0 generate-test-files C:\repos\Firebase Demos\firebaseui-web
> ./buildtools/generate_test_files.sh

Answer 1

> ./buildtools/generate_test_files.sh

这里只省略点斜线（ ./ ）

但是，如果您愿意，可以使用.\\\\ （因为单个 '\\' 会跳过下一个字符）并且它会起作用。

Answer 2

虽然这个问题很老，但当我与另一个使用另一个操作系统（Linux x Windows）的开发人员合作时，我遇到了同样的问题。 在项目开始时，脚本.sh因操作系统而失败。 合并某个分支后，我们不得不不断修改json文件。 我们提出的解决方案是附加用于调用脚本的shell，例如我们将初始化脚本更改为

...
{
start: bash ./myscript && npm run start
}
...

它在 Linux 和 Windows 上的 Gitbash 上运行良好。
