Question

我尝试使用命令gem uninstall dm-core卸载datamapper。

但似乎还需要卸载一大堆依赖宝石。

C:\>gem uninstall dm-core

You have requested to uninstall the gem:
        dm-core-0.9.11
dm-migrations-0.9.11 depends on [dm-core (= 0.9.11)]
dm-cli-0.9.11 depends on [dm-core (= 0.9.11)]
dm-serializer-0.9.11 depends on [dm-core (= 0.9.11)]
dm-timestamps-0.9.11 depends on [dm-core (= 0.9.11)]
dm-aggregates-0.9.11 depends on [dm-core (= 0.9.11)]
dm-types-0.9.11 depends on [dm-core (= 0.9.11)]
dm-is-tree-0.9.11 depends on [dm-core (= 0.9.11)]
dm-observer-0.9.11 depends on [dm-core (= 0.9.11)]
dm-validations-0.9.11 depends on [dm-core (= 0.9.11)]
If you remove this gems, one or more dependencies will not be met.

我尝试查找“gem uninstall”的文档，但似乎没有办法自动卸载依赖项：

我错过了什么吗？

Answer 1

gem list | cut -d" " -f1 | xargs gem uninstall -aIx删除所有已安装的红宝石宝石！

Answer 2

据我所知你是对的，没有一种简单的方法可以内置到gem命令来执行此操作。

但是，您可以查看gem-prune，它可以在您删除dm-core后帮助清理您的gem存储库。

Answer 3

我最终做了一个简单的command line tool to gem uninstall dependencies recursively。

我还向gem uninstall dependencies recursively提交了一个rubygems问题。

该rubygems问题已经关闭，在有人提供包含测试的补丁之前不会考虑。

Answer 4

for gem in `gem list --no-version`; do
  gem uninstall -aIx $gem
done

最适合我，不知道为什么，但

gem list | cut -d" " -f1 | xargs gem uninstall -aIx

对我的系统不起作用，因为它仍然抱怨......

ERROR:  While executing gem ... (Gem::InstallError)
    cannot uninstall, check `gem list -d some-gem-here`

Answer 5

运行这些卸载时的问题是它们按顺序排列在宝石列表中，因此如果可以卸载口音，那么最终会卡住。运行以下几次，它应该删除允许的所有宝石。

gem list | cut -d" " -f1 | sort -R | xargs -n1 gem uninstall -aIx

Answer 6

gem cleanup应该做到这一点。有关详细信息，请参阅here。

Answer 7

这段代码为我做了：

def gem_deps(name)
  if `gem dependency #{name}` =~ /(Gem #{name}-.*?)(Gem|\z)/m
    $1.split("\n").grep(/runtime\s*\)/).map do |line|
      line[/[\w-]+/]
    end.compact
  else
    []
  end
end

def gem_recursive_uninstall(name)
  deps = gem_deps(name)
  if deps.empty?
    system('sudo','gem','uninstall',name)
  else
    puts("Uninstall #{name} with dependencies: #{deps.join(', ')}? [y/n]")
    if gets.chomp[/y/]
      system(*(%w{sudo gem uninstall} + [name] + deps))
    end
  end
end

Answer 8

如果您想使用一些通配符来删除某些宝石（例如从特定供应商中删除一些宝石），那么您可以将gem list的输出传输到grep，如下所示

gem list --no-version | grep "opener-" | cut -d " " -f1  | xargs gem uninstall -aIx

上面的命令会删除名称以＆＃34; opener - ＆＃34;开头的所有宝石。

Answer 9

只需列出您要卸载的所有宝石，例如gem uninstall dm-migrations dm-cli dm-observer。并尝试尽可能使用Bundler管理您的宝石。

我是否必须手动卸载所有依赖宝石？
