在使用Capistrano映射進行部署時出現的psych.rb錯誤在這種情況下不允許使用

Question

我想部署一個Rails應用程序到CentOS 6/nginx /乘客服務器，但cap部署：cold給了我一個錯誤。以下是部署輸出的相關部分：

Rails 3.2.1。

提到的manifest.yml文件包含'jquery.min.map' - 那是'映射不允許'部分指的是什麼？如果是這樣，我不能解決如何阻止jQuery試圖包含這個映射文件。

我試過把manifest.yml文件的上下文通過各種在線驗證器 - 它會很好。據我所知，沒有缺失的空格或標籤。

謝謝！

Answer 1

我解決了這個問題。因爲Capistrano的deploy/assets.rb中的文件使用YAML.load，所以正在調用Psych。

它正在加載的變量是命令行cat命令的「捕獲」，並且因爲我的.bashrc中有語法錯誤，所以它捕獲錯誤的輸出並將它傳遞給YAML.load。修正了.bashrc錯誤，一切都很好！

Answer 2

我有這個問題，並根據myapp/shared/assets刪除了我的.json清單文件，建議here（實際上，他們建議將它們重命名，但這對我不起作用）。
