Bundler无法为Rails 4.0.0的gem“railties”找到兼容的版本。

I am trying to upgrade to Rails 4.0.0, and I changed the gem versions of sass-rails and coffee-rails. I need to resolve this gem conflict between rails and coffee-rails before I can upgrade to Rails 4.

我正在尝试升级到Rails 4.0.0，并更改了sassrails和咖啡Rails的gem版本。在升级到rails 4之前，我需要解决rails和咖啡rails之间的这个gem冲突。

When I ran bundle update this is the output I got:

当我运行bundle update时，这是我得到的输出:

Also bundle update only allows you to update one gem at a time, which is hard if you are updating to Rails 4 and a whole lot of gems have to be updated at the same time.

另外，捆绑更新只允许您一次更新一个gem，如果您要更新到Rails 4，那么您将很难同时更新所有的gem。

I solved this by deleting the Gemfile.lock and doing bundle install.

我通过删除Gemfile解决了这个问题。锁定并执行bundle安装。

This is of course assuming you have no conflicting explicit gem version in your Gemfile to start with. So if this fails, remove version numbers from the Gemfile.

这当然是假设您的Gemfile中没有明确的gem版本。因此，如果失败，请从Gemfile中删除版本号。

#2

Just remove gem versions (coffee-rails and sass-rails) from Gemfile and run bundle update

只需从Gemfile中移除gem版本(咖啡-rails和sassrails)，并运行bundle update。

#3

You have an outdated version of Devise, use Rails 4 compatible

您有一个过时的设计版本，使用Rails 4兼容。

gem 'devise', '~> 3.0.0.rc'

Also change coffee-rails to

也改变coffee-rails

gem 'coffee-rails', '~> 4.0.0'

and try doing

试着做

bundle update coffee-rails

#4

Run gem update rails first, then bundle update

先运行gem更新rails，然后捆绑更新。

#5

You have gems that aren't supported by Rails 4. Comment out all the gems except for Rails 4 and uncomment them one at a time after running bundle install to find the culprits. You might need to undo some of your version locks.

您有不受Rails 4支持的gem。注释掉除了Rails 4之外的所有gems，并在运行bundle安装之后对它们取消注释，以查找原因。您可能需要撤销一些版本锁。

#6

Delete the Gemfile.lock file
