Question

我正在努力改变Heroku上的Ruby版本。我使用带有rails 4的Ruby 2.0.0。

我的Gemfile有：

source 'https://rubygems.org'
ruby '2.0.0'
...

Heroku中的路径指向：

$ heroku config -s | grep PATH
PATH=bin:vendor/bundle/ruby/1.9.1/bin:/usr/local/bin:/usr/bin:/bin

当我推送我的应用时，我可以看到：

Fetching repository, done.
Counting objects: 7, done.
Delta compression using up to 4 threads.
Compressing objects: 100% (4/4), done.
Writing objects: 100% (4/4), 431 bytes | 0 bytes/s, done.
Total 4 (delta 3), reused 0 (delta 0)

由于Heroku说Using Ruby version: ruby-2.0.0，它检测到了我的Ruby版本。但是，当我运行$ heroku run rake db:migrate或heroku run 'ruby -v'时它回来了：

Your Ruby version is 1.9.2, but your Gemfile specified 2.0.0

如何在Heroku上将Ruby版本更改为2.0.0？

结论：我注意到我的rails应用程序有.bash_profile文件，但它有一个错误的路径。路径扰乱了我的heroku路径为ruby版本。

感谢大家的帮助:)

Answer 1

您是否在本地执行了bundle update，然后提交了文件Gemfile.lock？

服务器正在使用Ruby 2，但如果未推送新的锁定文件，应用程序仍配置为使用旧版本。

查看正在运行的版本：

$ heroku run console
> RUBY_VERSION

如果版本是正确的，您指定的版本，那么您有捆绑问题。只需重新安装即可。

gem install bundler

我推荐一个完整而干净的版本：

bundle clean --force
gem install bundler
bundle install

Answer 2

您正在使用Bundler版本1.3.2

确保升级到版本Bundler 2.0 +

然后最后一次捆绑并将您的更改推送到Heroku

我希望有帮助..

Answer 3

这是一个充满希望的远景，但也许尝试运行heroku ps：restart并希望它能够获得新的Ruby版本。

Heroku Ruby版本不升级？
