I changed the rails line in my app's Gemfile from:
我更改了我的应用程序的Gemfile中的rails行：
gem 'rails', '4.2.3'
To:
至：
gem 'rails', '5.0.0'
Per the rails documentation on the upgrade process. I then ran bundle update rails. I then hit a roadblock:
根据升级过程中的rails文档。然后我运行了bundle update rails。然后我遇到了障碍：
Bundler could not find compatible versions for gem "railties":
In Gemfile:
dotenv-rails (= 2.0.2) was resolved to 2.0.2, which depends on
railties (~> 4.0)
rails (= 5.0.0) was resolved to 5.0.0, which depends on
railties (= 5.0.0)
As I understand, railties is part of rails? So that seemed weird. To humor the error, I added:
据我所知，铁路是轨道的一部分？所以这看起来很怪异。为了幽默这个错误，我补充道：
gem 'railties', '5.0.0'
Then bundle update railties yields:
然后捆绑更新铁路产量：
Bundler could not find compatible versions for gem "activerecord":
In snapshot (Gemfile.lock):
activerecord (= 4.2.3)
In Gemfile:
annotate was resolved to 2.7.2, which depends on
activerecord (< 6.0, >= 3.2)
rails (= 5.0.0) was resolved to 5.0.0, which depends on
activerecord (= 5.0.0)
I follow the rabbithole and add:
我跟着rabbithole并添加：
gem 'activerecord', '5.0.0'
bundle update activerecord yields...
捆绑更新activerecord产量...
You have requested:
railties = 5.0.0
The bundle currently has railties locked at 4.2.3.
Try running `bundle update railties`
The whole reason I am even updating active record is so that I can update railties... it's running me in circles.
我甚至更新活动记录的全部原因是我可以更新铁路......它让我圈起来了。
If I run bundle update with my full Gemfile now (activerecord and railties added):
如果我现在用我的完整Gemfile运行bundle update（添加了activerecord和railties）：
Bundler could not find compatible versions for gem "railties":
In Gemfile:
devise (~> 3.5.6) was resolved to 3.5.6, which depends on
railties (< 5, >= 3.2.6)
rails (= 5.0.0) was resolved to 5.0.0, which depends on
railties (= 5.0.0)
rails (= 5.0.0) was resolved to 5.0.0, which depends on
railties (= 5.0.0)
I'll admit I'm not a total pro at this process. Is there anything I am missing? Has anyone experienced something like this during their upgrade process?
我承认我不是这个过程的全职员工。有什么我想念的吗？在升级过程中有没有人经历过这样的事情？

First error means bundle update dotenv-rails, if you are restricting the version make sure it's to one that supports railties 5. Based on your updates, it seems you are in a older devise too. So try to update both at the same time:
第一个错误意味着捆绑更新dotenv-rails，如果您要限制版本，请确保它是支持railties的版本5.根据您的更新，您似乎也处于较旧的设计中。因此，请尝试同时更新两者：
bundle update dotenv-rails devise, make sure you read the update notes in dotenv-rails and devise and change anything that needs to be change in your code.
捆绑更新dotenv-rails设计，确保您阅读dotenv-rails中的更新说明，并设计和更改代码中需要更改的任何内容。
My advise: go to the closest version that supports rails 5 first, so for devise that's 4.0.3 and dotenv-rails 2.1.2. Set this restrictions in your Gemfile before you bundle update. Only after you update this gems successfully attempt to update rails. Add any other gem that comes up to this same process.
我的建议：首先转到支持rails 5的最近版本，所以设计为4.0.3和dotenv-rails 2.1.2。在捆绑更新之前，在Gemfile中设置此限制。只有在您更新此gems后才能成功尝试更新rails。添加出现在同一进程中的任何其他gem。
