使用模板 URL 運行 rails new 失敗並顯示 HTTP 錯誤代碼 406

Question

我正在使用 Rails 5.0.0 和 Ruby 2.5

rails new命令采用名為-m的選項，該選項應該允許您將 url 傳遞給模板。 參考文檔

但是，當我嘗試將 url 傳遞給我在Github上的一個非常簡單的模板文件時，我收到了406 Not Acceptable HTTP Error Code。

這是我正在運行的命令::

rails new helloworld -m https://github.com/jw81/Rails_Templating/blob/master/template.rb

這是我得到的錯誤::

apply  https://github.com/jw81/Rails_Templating/blob/master/template.rb

我可以下載template.rb文件並將文件的磁盤位置傳遞給-m選項，它工作得很好。 但是將 Github URL 傳遞給-m不起作用。

有沒有其他人遇到過這個問題，如果我做錯了什么，可以告訴我嗎？

您需要提供原始文件的鏈接，而不是顯示文件的 html 頁面。 對於您示例中的文件，該鏈接是：

https://raw.githubusercontent.com/jw81/Rails_Templating/d63247b282bef19ae5ac64504089fa83baafbcec/template.rb

您可以通過單擊標題右側的“原始”按鈕來獲取 github 上任何文件的原始鏈接。
