Question

我一直在尝试将我的Rails应用程序从5.1.0rc1迁移到5.1.0。

这是我的宝石文件：

Exception in thread "main" java.io.IOException: can't find class file
MyClass.class in 
java.net.URLClassLoader{urls=[file:/usr/lib/jvm/java-1.5.0-gcj-4.8-amd64/jre/lib/rt.jar], 
parent=gnu.gcj.runtime.SystemClassLoader{urls=[file:./], parent=gnu.gcj.runtime.ExtensionClassLoader{urls=[], parent=null}}}
               at gnu.classpath.tools.javah.Main.getClass(libgcj-tools.so.14)
               at gnu.classpath.tools.javah.Main.parseClasses(libgcj-tools.so.14)
               at gnu.classpath.tools.javah.Main.run(libgcj-tools.so.14)
               at gnu.classpath.tools.javah.Main.main(libgcj-tools.so.14)

这是我从捆绑安装中获得的：

gem 'rails', '~> 5.1.0'
gem 'mysql2', '>= 0.3.18', '< 0.5'
gem 'puma', '~> 3.0'
gem 'sass-rails', '~> 5.0'
gem 'turbolinks', '~> 5'
gem 'uglifier', '>= 1.3.0'
gem 'redis', '~> 3.3.3'
gem 'redis-rails', '~> 5.0.1'
gem 'jbuilder', '~> 2.5'
gem 'sidekiq', '~> 4.2.10'
gem 'active_model_serializers', '~> 0.10.5'
gem 'jwt', '~> 1.5.6'
gem "mini_magick", '~> 4.7.0'
gem 'rack-cors', "~> 0.4.1"
gem 'mandrill-api', "~> 1.0.53"
gem 'curb', "~> 0.9.3"
gem 'inherited_resources', '~> 1.7'
gem 'activeadmin', '~> 1.0.0'
gem 'coffee-rails', '~> 4.2.1'
gem 'therubyracer', git: 'https://github.com/cowboyd/therubyracer.git'
gem 'meta-tags', '~> 2.4.0'
gem 'slim', '~> 3.0.7'

可能出现什么问题？

如果它有帮助（但我怀疑），我在Docker容器上工作。我删除了Bundler could not find compatible versions for gem "actionpack": In Gemfile: active_model_serializers (~> 0.10.5) was resolved to 0.10.5, which depends on actionpack (< 6, >= 4.1) activeadmin (~> 1.0.0) was resolved to 1.0.0, which depends on formtastic (~> 3.1) was resolved to 3.1.5, which depends on actionpack (>= 3.2.13) activeadmin (~> 1.0.0) was resolved to 1.0.0, which depends on inherited_resources (~> 1.7) was resolved to 1.7.0, which depends on actionpack (< 5.1, >= 3.2) rails (~> 5.1.0) was resolved to 5.1.0, which depends on actionpack (= 5.1.0) rails (~> 5.1.0) was resolved to 5.1.0, which depends on actionpack (= 5.1.0) rails (~> 5.1.0) was resolved to 5.1.0, which depends on actionpack (= 5.1.0) activeadmin (~> 1.0.0) was resolved to 1.0.0, which depends on ransack (~> 1.3) was resolved to 1.8.2, which depends on actionpack (>= 3.0)以避免冲突。

此处有问题的宝石是inherited_resources的{{1}}，当您提出问题时，其最新版本指定为actionpack (< 5.1, >= 3.2)。

也许令人惊讶的是，您之前的候选版本的actionpack 5.1.0.rc1满足< 5.1约束，因此您无法阻止升级到候选版本，但是已被阻止从最终版本中删除。

新版本的inherited_resources已于5月3日被删除，这将有固定的内容，但请注意，当前gemspec表示当Rails转到5.2时，您将遇到相同的问题。

Rails 5.1.0rc1到5.1.0迁移缺少兼容的actionpack
