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

也bundle update只允许您一次更新一个 gem，如果您要更新Rails 4并且必须同时更新大量 gem ，这会很困难。

I solved this by deleting the Gemfile.lockand doing bundle install.

我通过删除Gemfile.lock和做来解决这个问题bundle install。

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

这当然是假设您开始时没有冲突的显式 gem 版本Gemfile。因此，如果失败，请从 Gemfile 中删除版本号。

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

只需从 Gemfile 中删除 gem 版本（coffee-rails 和 sass-rails）并运行bundle update

回答by andreofthecape

Run gem update railsfirst, then bundle update

运行gem update rails，然后再bundle update

You have an outdated version of Devise, use Rails 4 compatible

你有一个过时的 Devise 版本，使用 Rails 4 兼容

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

Also change coffee-railsto

也coffee-rails改为

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

and try doing

并尝试做

bundle update coffee-rails

回答by penner

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 Rails 4 不支持的 gem。在运行 bundle install 以找到罪魁祸首后，注释掉除 Rails 4 之外的所有 gem，并一次取消注释它们。您可能需要撤消某些版本锁定。
