我对 Ruby 和一般编程比较陌生。我在大约 6 个月前创建了这个应用程序，它搜索顶级 twitter 和 google 趋势以输出 youtube 中所有最受欢迎视频的 JSON 文件。我已经将它部署到 Heroku 并且在 twitter api 1 更新到 api 1.1 之前没有任何问题。6 个月前，为了了解在本地和 heroku 中运行的 twitter 趋势，我的代码看起来像这样。

    if trendLocation == nil
        result = JSON.parse(open("https://api.twitter.com/1/trends/1.json").read)
    end

    if trendLocation.to_i == 23424977
        result = JSON.parse(open("https://api.twitter.com/1/trends/23424977.json").read)
    end

    topTen = result.first["trends"]
    panelArray = Array.new

( https://api.twitter.com/1/trends/23424977.json ) 曾经是一个开源软件，它直接为我提供了 twitter 的热门趋势（无需身份验证）。自从 Twitter API 1.1 更新以来，链接不再存在，我必须对我的应用程序进行身份验证才能了解趋势。现在，每次我在 Url 中调用 Twitter 趋势时，我的应用程序都会崩溃。但是当我呼吁谷歌趋势时，它在本地和 Heroku 中运行得非常好。

所以我下载了 'twitter' 和 'oauth' gem 来使用 Twitter::Client 验证我的应用程序。我把我的代码改成了这个。

def getPanelsForTwitter(panelMaxCount)

    client = Twitter::Client.new(
        :consumer_key => 'XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX',
        :consumer_secret => 'XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX',
        :oauth_token => 'XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX',
        :oauth_token_secret => 'XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX'
    )

    usa = client.trends(23424977)
    world = client.trends(1)

    trendLocation = params[:woeid]

    if trendLocation == nil
        result = world
    end

    if trendLocation.to_i == 23424977
        result = usa
    end

    panelArray = Array.new      

end

一切都在本地运行并完成它需要做的一切（例如获取 twitter 和 google 趋势、在 youtube 上搜索并显示视频结果）。但是当我将它推送到 Heroku 时，应用程序崩溃了，但是当我将它推送或部署到 Heroku 时，它无法运行。

我运行了heroku日志，这就是我得到的

我得到的第一个错误是（3.2.9/lib/active_support/dependencies.rb:317:in `rescue independ_on': No such file to load -- oAuth (LoadError)）。

所以我假设我的宝石有问题，我认为本地的宝石和 heroku 中的宝石不匹配。

这是我的 gemfile.lock

当我在本地运行 gem list 和运行 heroku run gem list 时，一切都匹配。我尝试卸载 'twitter' 和 'oauth' gems，然后重新安装并运行 bundle install，但仍然遇到同样的问题。

在目前的状态下，我的应用程序只能在本地运行，根本不能在 Heroku（live）中运行，即使我试图只获取谷歌趋势。整个应用程序崩溃。

当我在 Heroku 中回滚到六个月前时，该应用程序仅在我从 twitter 调用某些内容时才会崩溃。其他一切都在 Heroku 中运行。

这让我相信，当它试图读取 gemfile 时，这是一个 Heroku 部署问题。正确的？我错过了什么吗？还有其他我可以使用的宝石吗？或者这不是宝石问题吗？

谢谢大家的意见。终于发现这有什么问题了。我很粗心，但这是一个简单的语法错误。我在heroku日志中的错误是..

`rescue in depend_on': No such file to load -- oAuth (LoadError)

我有一个单独的 temps_controller，它有一个我完全忘记的 require 'oAuth'。宝石“oAuth”不存在，它被认为是“oauth”。这就是应用程序在部署到 heroku 时崩溃的原因。我有点惊讶和困惑为什么它在本地工作。我猜 localhost 对这些错误更宽容？

当我部署到实时站点时，我真的应该小心。通过删除我用于测试的所有临时文件，确保清理我的代码。也许避免在控制器中使用 require 。只需安装所需的 gem。

这是一个如此简单而愚蠢的错误，花了我一点时间，但绝对学到了很多东西。

我认为您在评论中得到了一些很好的答案，但您可能还想查看Twitter Gem以确保您不会将您的公共 API 密钥扔到可能受到损害的地方
