忽略GEM，因为没有构建它的扩展

在我的工作电脑和家用电脑上，我最近使用Ruby -install将Ruby升级到2.3.1。我使用chruby作为Ruby切换器。

我开始在我的终端上看到这样的警告:

Ignoring bcrypt-3.1.11 because its extensions are not built.  Try: gem pristine bcrypt --version 3.1.11
Ignoring bcrypt-3.1.10 because its extensions are not built.  Try: gem pristine bcrypt --version 3.1.10
Ignoring binding_of_caller-0.7.2 because its extensions are not built.  Try: gem pristine binding_of_caller --version 0.7.2
Ignoring byebug-9.0.5 because its extensions are not built.  Try: gem pristine byebug --version 9.0.5
Ignoring byebug-5.0.0 because its extensions are not built.  Try: gem pristine byebug --version 5.0.0
Ignoring concurrent-ruby-ext-1.0.2 because its extensions are not built.  Try: gem pristine concurrent-ruby-ext --version 1.0.2
Ignoring debug_inspector-0.0.2 because its extensions are not built.  Try: gem pristine debug_inspector --version 0.0.2

在我的工作电脑上，清单要长得多，但很容易解决。当我尝试建议的gem原始gem时，它告诉我找不到宝石，所以我运行gem安装gem，这就解决了问题。

在家里，一切都不正常。

我从常识和其他Stack问题中尝试过的事情:

gem pristine GEM gem pristine --all uninstalling and reinstalling the gem gem update gem update --system bundle update uninstalling and reinstalling bundler uninstalling and reinstalling rails (Though, it's not a Rails specific problem.) deleting ~/.bundle/ opening XCode and letting it install some extensions (It did need to do it, but it didn't fix anything.) running brew doctor and solving all the minor issues, then brew update and brew upgrade gem install curb (I can't imagine what this gem has to do with this issue, but two different people listed it as the last step of their fix to the same warning.)

当前回答

就我而言，我试图保持原始状态——但我得到的是:

Ignoring ffi-1.11.1 because its extensions are not built.  Try: gem pristine ffi --version 1.11.1
Ignoring jaro_winkler-1.5.3 because its extensions are not built.  Try: gem pristine jaro_winkler --version 1.5.3
Ignoring psych-3.1.0 because its extensions are not built.  Try: gem pristine psych --version 3.1.0
/.rbenv/versions/2.3.1/lib/ruby/2.3.0/rubygems/core_ext/kernel_require.rb:55:in `require': incompatible library version - /.gem/gems/psych-3.1.0/lib/psych.bundle (fatal)

然后，我删除了Users/{{user.name}}} /⁨.gem上的内容，然后当我需要运行bundle install—force时，它重新安装了所有内容，然后命令原始—一切都按预期工作

在Ubuntu中，这对我来说很有效。

TL;DR - Ruby宝石不喜欢红宝石从符号链接中运行或从它们构建的地方移动(因为嵌入式shebangs)

如果Ruby目录被调用，或者环境变量指向一个符号链接的目录，或者被复制或重命名，就可能出现此消息。我使用chruby和符号链接/opt/rubies/ -> /usr/local/ Ruby /，但Ruby的动态库查找逻辑不能很好地发挥这一点。

在我的案例中，解决方案是将符号链接替换为/opt/ Ruby /中的实际红宝石，并运行gem质朴——所有这些都在每个Ruby中。对于其他使用RVM或Rbenv的用户，祝您好运，不必从头开始。

这可能不是你的问题，但希望它能有所帮助。

我遇到了这个问题，并执行了与上面相同的所有命令，甚至删除了之前安装的所有Ruby版本。然而，错误仍然存在。
