这些是我得到的错误，我不知道是否在我的图片中。以前，我将我的图像保存在我的封面文件夹中，然后将我的封面文件夹重命名为封面，仍然没有进入heroku push
答案 0 :(得分：0)
尝试
RAILS_ENV=production rake assets:precompile
并推送到heroku。
在本地生产环境中检查您的应用。
答案 1 :(得分：0)
Git不会检查你推的是什么，但是Heroku的确如此。您的资产似乎有错误。通常这是CSS文件中的错误。检查错误在哪一行并更正。然后再次推送到git，然后再次尝试推送到Heroku。当您的应用程序编码正确时，推送到Heroku应该没有问题。检查您的资产或在此处发布完整的错误日志，以便我们可以查看资产中的错误位置。
在您的情况下，这是一个JS文件的问题。
ExecJS::RuntimeError: SyntaxError: Unexpected token: operator (<) (line: 14589, col: 0, pos: 440984)
at new JS_Parse_Error
根据Heroku的输出，您应该能够找出问题所在。或者只是试着没有那个javascript文件。这至少可以保证成功推送，您可以稍后编辑JS文件。
提示：在
之后检查Heroku日志rake aborted!
编辑：下载版本中的标准bootstrap javascript文件应该可以正常工作。可能是你编辑过的东西？它非常规，但您可以为部署目的删除.js文件扩展名。例如.js__ 并且Heroku不会将其视为JS文件。问题解决了。无需删除文件夹中的所有文件。 如果你不喜欢这个解决方案，你应该拿出来 // require * tree 来自你的application.js 或从rails应用程序中取出所有不正确的JS文件。
javascript文件夹可以保留。问题是Javascript文件中的错误JAVASCRIPT。请找到错误的文件，并禁止它如上所述进行预编译。如果您只有bootstrap.js文件而不是更改文件扩展名或从应用程序中删除它。部署错误应该像这样解决。
