Question

我在Heroku中有一个现有的Rails应用程序，正在尝试将其推送到该位置，但是每次我尝试将其推送到Heroku时，都会出现此错误

There was an error parsing your Gemfile, we cannot continue
remote:  !     /app/tmp/buildpacks/b7af5642714be4eddaa5f35e2b4c36176b839b4abcd9bfe57ee71c358d71152b4fd2cf925c5b6e6816adee359c4f0f966b663a7f8649b0729509d510091abc07/vendor/ruby/heroku-18/lib/ruby/2.5.0/rubygems.rb:289:in `find_spec_for_exe': can't find gem bundler (>= 0.a) with executable bundle (Gem::GemNotFoundException)
remote:  !     from /app/tmp/buildpacks/b7af5642714be4eddaa5f35e2b4c36176b839b4abcd9bfe57ee71c358d71152b4fd2cf925c5b6e6816adee359c4f0f966b663a7f8649b0729509d510091abc07/vendor/ruby/heroku-18/lib/ruby/2.5.0/rubygems.rb:308:in `activate_bin_path'
remote:  !     from /tmp/d20190617-88-bonyg7/bundler-2.0.1/bin/bundle:23:in `<main>'

从那里，我认为最突出的是：

There was an error parsing your Gemfile, we cannot continue
can't find gem bundler (>= 0.a) with executable bundle (Gem::GemNotFoundException)

我的Gemfile.lock指出我的应用已与2.0.2捆绑在一起

当我做gem list时，捆绑器零件会给我这个bundler (default: 2.0.2, default: 1.17.2)

感谢您的帮助！谢谢！

编辑：这是我的宝石文件

这里的问题是Heroku无法使用您要求他使用的捆绑软件。当您要求Heroku使用他们知道的捆绑软件时，可以使用许多解决方案对其进行修复（据我所知，2.0.2不起作用）。

打开Gemfile.lock并在文件末尾替换

BUNDLED WITH
2.0.2

使用

BUNDLED WITH
2.0.1

要长期解决此问题，您只需gem uninstall bundler然后运行gem install bundler -v 2.0.1

推送到Heroku时解析Gemfile时出错
