Bundler无法为Rails 4.0.0找到gem"railties"的兼容版本

Question

我想升级到Rails的4.0.0,和我换的宝石版本sass-rails和coffee-rails.我需要在升级到Rails 4之前rails和coffee-rails之前解决这个gem冲突.

当我运行时,bundle update这是我得到的输出:

$ bundle update
Updating git://github.com/pilu/web-app-theme.git
Fetching source index from https://rubygems.org/
Resolving dependencies..............
Bundler could not find compatible versions for gem "railties":
  In Gemfile:
    rails (= 4.0.0) ruby depends on
      railties (= 4.0.0) ruby

    coffee-rails (= 4.0.0) ruby depends on
      railties (4.0.0.rc2)

Answer 1

此外,bundle update只允许您一次更新一个宝石,如果您要更新,这很难,并且必须同时更新Rails 4大量宝石.

我通过删除Gemfile.lock和执行来解决这个问题bundle install.

这当然是假设您在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.

Answer 2

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

Answer 3

你有一个过时的Devise版本,使用Rails 4兼容

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

也coffee-rails改为

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

并尝试做

bundle update coffee-rails

Answer 4

先跑gem update rails,然后bundle update

Answer 5

你有Rails不支持的宝石4.注释掉除了Rails 4之外的所有宝石,并在运行bundle install之后一次取消注释它们以找到罪魁祸首.您可能需要撤消某些版本锁定.
