Question

突然之间我无法推送到Heroku而且我已经达到了构建成功的程度，但是在编译时我看到了以下内容：

remote: -----> Build succeeded!
remote: -----> Ruby app detected
remote: -----> Compiling Ruby/Rails
remote: sh: 1: gem-install-bundler: not found
remote: sh: 1: gem-install-bundler: not found
remote:  !

从我可以收集到的内容中，我认为我需要更新bundler，因此我将bundler更新到版本1.15.2，并尝试再次将其推送，但显示相同的错误。我的gemfile.lock甚至说BUNDLED WITH 1.15.2。

我有什么遗失的吗？

Answer 1

我联系了Heroku，他们告诉我我有多个buildpack：

感谢您就安装红宝石的问题与我们联系。看来这个应用程序有两次指定的Heroku Buildpack for Ruby，后者指定主版本而不是发布版本版本：

{{ variable }}

然后他们继续告诉我如何解决这个问题：

你可以尝试一次指定每个buildpacks 使用已发布的版本来查看问题是否存在？

$ heroku buildpacks -a app-name
=== app-name Buildpack URLs
1. heroku/ruby
2. https://github.com/heroku/heroku-buildpack-nodejs.git
3. https://github.com/heroku/heroku-buildpack-ruby.git

这解决了一切！

Answer 2

您是否将生成的Gemfile.lock检入版本控制

git add Gemfile.lock

Heroku：由于gem install bundler，无法推送到Heroku
