从4.2升级后捆绑w/Rails 5.0.6时出现Bundler错误

Question

尝试将Ruby 2.2/Rays 4.2升级到Rails 5.0.6(在5.0.7.2上已经放弃了，因为它似乎需要Zeitwerk，而Zeitwer需要Ruby>=2.4.4(

Bundler could not find compatible versions for gem "actionmailer":
In Gemfile:
premailer-rails was resolved to 1.11.1, which depends on
actionmailer (>= 3)
rails (= 5.0.6) was resolved to 5.0.6, which depends on
actionmailer (= 5.0.6)

现在，我的gem文件中有gem "rails", '5.0.6'，没有actionmailer的列表。actionmailer 5.0.6似乎可以满足这两个要求，那么bundler为什么会抱怨(我确实在bundle update命令中列出了actionmailer(呢？更重要的是，我能做些什么来克服这个问题？

在之前的Rails升级中，我删除了gemfile.lock并进行了bundle install，最终使其正常工作。所以我在这次升级中尝试了一下，结果却出现了同样的错误。我也尝试了bundle update --all，但也出现了同样的错误。

这是Gemfile:

Answer 1

以下是我解决此问题的方法。

1. 从Gemfile中删除所有gem的版本(Ruby和Rails除外(
2. 删除Gemfile.lock
3. 捆绑安装

在我的案例中，我在带有本机扩展的gem上遇到了许多构建错误。大多数都与CLANG(Mac OS X C编译器(的更改有关，要求我在gem安装中添加-- --with-cflags="-Wno-error=implicit-function-declaration"。
