Heroku 安装 Bundler 然后抛出错误 Bundler 2.0.1
Heroku installs Bundler then throws error Bundler 2.0.1
我正在尝试将 Rails 应用程序部署到 Heroku。我在那里部署任何东西已经有一段时间了，但我对这里发生的事情一头雾水。
这是一个相当基础的 Rails5 应用程序。部署顺利通过 Gemfile，然后失败并出现错误，要求我安装 Bundler v 2.0.1。这是日志的有趣部分：

我不明白这是怎么回事，因为 Heroku 似乎 运行 顺利完成部署，然后删除捆绑器，然后在 rake 任务上抛出错误并再次请求捆绑器。我已经执行了 RAILS_ENV=production bundle exec rake assets:precompile，并且显示的是最新的。我一定在这里遗漏了一些东西，希望最近有 Heroku 经验的人可以指出。

我 运行 bundle exec rake -P 命令也没有失败
我通过升级到 Ruby 2.6.3 和 Bundler 2.0.2 修复了我们在 Heroku 上的构建。
我们在 Heroku 上的构建在过去几天开始出现故障，并出现类似的错误消息：
Could not find 'bundler' (2.0.1) required by your ... Gemfile.lock.
我们在本地构建中使用 Ruby 2.6.1 和 Bundler 2.0.1，运行良好。直到几天前，这个组合在 Heroku 上也运行良好。
在搜索 Heroku 文档时，我注意到这个 Dev Center article，它于 2019 年 6 月 26 日更新。它指出：
Bundler 2.0.2
See issues for 2.0.1.
Many people are hitting issue 4 which is only triggered when a new Bundler version is released. It happens because of a bug in Rubygems, and can be fixed by upgrading to 2.5.5+ or 2.6.3+.
2.0.1 下的第 4 期指出：
[You may get an error] due to a bug in the Rubygems bundler version checking code. To avoid this issue, upgrade your Ruby version. It is fixed in 2.5.5+ and 2.6.3+. If you do not update, your Ruby version then every new release of Bundler 2.x will trigger this issue.
Bundler 2.0.2 于 2019 年 6 月 13 日发布，看起来 Heroku 已经开始使用它了。
我注意到您正在使用日志中的 Ruby 2.7。我建议在您的 Gemfile 中指定 ruby '2.6.3'，安装 Bundler 2.0.2，并使用该组合 bundling/generating 您的 Gemfile.lock。然后您应该在锁定文件的底部看到它，希望您的应用程序在 Heroku 上成功构建：
RUBY VERSION
ruby 2.6.3p62
BUNDLED WITH
2.0.2
很可能，您需要 运行 解决这个问题
gem install bundler -v 2.0.2
bundle update --bundler
提交它在您的 Gemfile.lock 中所做的更改，然后您的下一次 Heroku 推送将顺利通过。
