“”未被识别为内部或外部命令(在为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。我克隆了github上的master分支，并简单地尝试运行"npm install“，但我在node package manager中遇到了一个从未遇到过的错误。我得到了

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

我也尝试了这个will cygwin64，得到了完全相同的结果。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

operable program or batch file.

Answer 1

虽然这个问题很老了，但当我与另一个使用另一个操作系统(Linux X Windows)的开发人员协作时，我遇到了同样的问题。在项目开始时，脚本.sh会失败，这取决于操作系统。在合并一些分支之后，我们不得不不断地修改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的Gitbash上都运行得很好。

Answer 2

> ./buildtools/generate_test_files.sh

这里只需要省略点斜杠(./)

不过，如果您愿意，您可以使用.\\ (因为单个'\‘将跳过下一个字符)，并且它可以工作。
