是什么原因导致此错误，该如何解决？
答案 0 :(得分：2)
同样的错误使我发疯，但最终我将Rails 5应用程序部署到了heroku。如此处https://devcenter.heroku.com/articles/ruby-support#libraries所述，Heroku将使用Bundler 2.0.2构建您的应用程序，并且这是不可配置的。看来您也在使用Bundler 2.0.1（可以在gemfile.lock的底部找到）。我运行了命令gem install bundler -v '2.0.2'
，然后我必须通过进入项目的根目录来更新gemfile.lock并运行bundle update --bundler，gemfile.lock现在应该显示正确的捆绑程序版本2.0.2。提交git中的更改并运行git push heroku master并瞧瞧！
答案 1 :(得分：0)
The documentation列出a number of issues with Bundler 2。看起来您正在使用Ruby 2.6.1，这意味着您受到了
的影响指定捆绑程序2.0.2的Gemfile.lock不适用于捆绑程序2.0.1
如果您尝试将使用捆绑器2.0.2的应用程序部署到带有捆绑器2.0.1的Heroku平台上，则可能会出现以下错误：
`find_spec_for_exe': can't find gem bundler (>= 0.a) with executable bundle (Gem::GemNotFoundException)这是由于Rubygems捆绑程序版本检查代码中的错误所致。为避免此问题，请升级您的Ruby版本。它在2.5.5+和2.6.3+中已修复。如果不更新，则为Ruby版本，则Bundler 2.x的每个新发行版都会触发此问题。
将Ruby升级到2.6.3或更高版本，在ruby中更改Gemfile版本，在本地重新运行bundle install，然后重新部署。
