無法在Heroku中推送我的Rails應用

Question

我已成功將Rails應用程序推送到git中，但無法推送到heroku中，我遇到了以下錯誤：

這些是我得到的錯誤，我不知道這是我的圖像中。 之前，我將圖像保存在Cover文件夾中，然后將Cover文件夾重命名為Cover，但仍無法在heroku push中使用

Answer 1

嘗試

RAILS_ENV=production rake assets:precompile

並推到heroku。

在本地生產環境中檢查您的應用。

Answer 2

Git不會檢查您推送的內容，但是Heroku會檢查。 您的資產似乎有錯誤。 通常，這是CSS文件中的錯誤。 檢查錯誤所在的行並進行更正。 比再次推送到git，然后再嘗試推送到Heroku。 如果您的應用程序編碼正確，則推送到Heroku應該沒有問題。 檢查您的資產或在此處發布完整的錯誤日志，以便我們查看您的資產中的錯誤位置。

您的情況是JS文件有問題。

ExecJS::RuntimeError: SyntaxError: Unexpected token: operator (<) (line: 14589, col: 0, pos: 440984)
at new JS_Parse_Error

根據Heroku的輸出，您應該能夠找出問題所在。 或者只是嘗試在沒有該javascript文件的情況下進行推送。 這至少可以保證成功推送，並且您以后可以編輯JS文件。

提示：之后檢查Heroku日志

rake aborted!

編輯：下載版本中的標准引導javascript文件應該可以工作。 可能是您編輯了嗎？ 這是非常規的，但出於部署目的，您只需刪除.js文件擴展名即可。 例如，.js__和Heroku不會將其視為JS文件。 問題解決了。 無需刪除文件夾中的所有文件。 如果您不喜歡該解決方案，則應從application.js中取出// // require * tree或從rails應用程序中取出所有不正確的JS文件。

javascript文件夾可以保留。 問題是Javascript文件中的JAVASCRIPT錯誤。 請找到錯誤的文件，並禁止其如上所述進行預編譯。 如果您只有bootstrap.js文件，則可以更改文件擴展名或將其從應用程序中刪除。 應該像這樣解決部署錯誤。
