'.' 不被識別為內部或外部命令（為 firebaseUI 運行 npm install 時）

Question

我無法在我的 firebaseUI 演示應用程序上安裝 npm 包。 我在 github 上克隆了 master 分支，只是嘗試運行“npm install”，但是我遇到了一個錯誤，我從未遇到過節點包管理器。 我得到

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

我也試過這將 cygwin64 並得到完全相同的結果。 下面是錯誤，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

> ./buildtools/generate_test_files.sh

這里只省略點斜線（ ./ ）

但是，如果您願意，可以使用.\\\\ （因為單個 '\\' 會跳過下一個字符）並且它會起作用。

Answer 2

雖然這個問題很老，但當我與另一個使用另一個操作系統（Linux x Windows）的開發人員合作時，我遇到了同樣的問題。 在項目開始時，腳本.sh因操作系統而失敗。 合並某個分支后，我們不得不不斷修改json文件。 我們提出的解決方案是附加用於調用腳本的shell，例如我們將初始化腳本更改為

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

它在 Linux 和 Windows 上的 Gitbash 上運行良好。
