几年前，我一直在 Windows 上使用 Netbeans，甚至在它成为 Apache Netbeans 之前。我仍然很乐意在 Apache Netbeans IDE 11.0 中使用Ruby2.4 + MSYS2和 Ruby 插件（Netbeans 8.2 插件门户可以在 Netbeans 11.0 IDE 中顺利使用），它可以帮助我在安装了 Fast Debugger 的情况下很好地调试 Ruby 代码（ruby-debug-ide gem) . 但是，由于一些限制，我必须迁移到 Ruby2.6.3。因此，我将我在 Ruby 2.4 中看到的所有 gem 都安装到了 Ruby 2.6 环境中，并期望它能够工作。

工具 >> Ruby 平台 >>（选择平台）Ruby 2.4.1-p111 >> Gem Manager >>（完美显示所有已安装）Ruby Gems

相似地

工具 >> Ruby 平台 >> （选择平台）Ruby 2.6.3-p62 >> Gem Manager >> Gems Fetching failed。

选择 Ruby 2.6.3 平台

宝石获取失败消息

在查看 Rubygems 的 Netbeans wiki 页面上的一些旧文档后，我发现Ruby Gems Fetching Failed它说，NetBeans 只是在后台使用gem工具。如果 gems 获取失败，请务必从命令行检查它是否有效，特别是以下命令：

宝石列表 --local --details

gem list --remote --details （我没有任何远程 gem，所以这个没有结果）

PS C:\Tools> gem list --local --details

我想知道为什么它可以与 Ruby 2.4 包一起使用并且无法为 Ruby 2.6.3 包获取 gem。Netbeans Ruby 论坛和邮件列表似乎已经退出历史，#netbeans IRC 似乎闲置，没有人回应。我提前感谢您提出的任何建议。

PS 除非 Gem Manager 正常工作，否则我无法调试任何程序 - 因为调试器不起作用。

问题

失败发生在Gem::Util.glob_files_in_dirRubyGems 3 中定义为：

def self.glob_files_in_dir(glob, base_path)
  if RUBY_VERSION >= "2.5"
    Dir.glob(glob, base: base_path).map! {|f| File.expand_path(f, base_path) }
  else
    Dir.glob(File.expand_path(glob, base_path))
  end
end

传递给该方法的参数是：

glob = "did_you_mean-*.gemspec"
base_path = "C:/Users/myuser/.gem/ruby/2.6.0:C:/Ruby26/lib/ruby/gems/2.6.0/specifications"

在较旧的 Ruby 版本中，此 base_path 参数将导致glob_files_in_dir返回[]. 较新的版本会引发参数错误。

解决方案

您可以通过手动设置 NetBean 的 gem 路径来解决此问题：

  1. 从菜单中，选择工具 > Ruby 平台
  2. 选择您的 Ruby 2.6 平台
  3. 在 Gem Path 列表中，选择现有值 - 例如“C:\Users\myuser.gem\ruby\2.6.0:C:\Ruby26\lib\ruby\gems\2.6.0”
  4. 单击删除
  5. 单击添加...
  6. 输入文件名“C:\Ruby26\lib\ruby\gems\2.6.0”
  7. 单击打开以选择文件夹
  8. 单击关闭关闭对话框

最后，平台应如下所示：
