Node.js ''；无法识别为内部或外部命令（在为firebaseUI运行npm安装时）

我无法在firebaseUI演示应用程序上安装npm软件包。 我克隆了github上的主分支，只是尝试运行“npm安装”，但我遇到了一个错误，我从未在node package manager中遇到过。我明白了

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

我还尝试了这个将cygwin64，并得到了完全相同的结果。下面是错误，下面是my package.json

firebaseui@3.3.0 generate-test-files C:\repos\Firebase Demos\firebaseui-web

./buildtools/generate_test_files.sh

这里省略点斜杠（

/

）

---

尽管如此，如果您愿意，您可以使用

\\\

（因为单个“\”将跳过下一个字符），而且它会起作用。

尽管这个问题很老，但我在与另一个使用另一个操作系统（Linux x Windows）的开发人员协作时遇到了同样的问题。 在项目开始时，根据操作系统的不同，脚本

.sh

失败。合并一些分支后，我们必须不断修改

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上都可以正常工作。

您知道。/导致此类问题的原因吗。不幸的是，你提出的建议不起作用
