在windows 10上安装ruby on rails时出错
我想要在Windows10上安装ruby on rails，按照这个视频中的相同说明：https://www.youtube.com/watch?v=G-B_KUFNkQQ
当它完成ruby的安装后，我返回到控制台，在gem安装rails之后，我得到了这个错误：
C:\Users\Usuario>gem install rails --no-document

Ensure you have either installed the shared-mime-info package for your distribution, or
obtain a version of freedesktop.org.xml and set FREEDESKTOP_MIME_TYPES_PATH to the location
of that file.

Ruby安装程序是Ruby2.7.2-1 (x64)，我的ruby版本是Ruby2.7.2p137 (2020-10-01修订版5445e04352) x64-mingw32

Windows10 ruby 2.6.2安装rails 6.0.0.rc1
- 从https://gitlab.freedesktop.org/xdg/shared-mime-info/uploads/0440063a2e6823a4b1a6fb2f2af8350f/shared-mime-info-2.0.tar.xz
- Extract下载共享mime信息，下载的包使用7Zip或WinRAR。
- 将其放置在您选择的位置，例如共享一个新的环境变量，名称为："C:\package".
- Set，浏览值为C:\shared-mime-info终端或CMD，例如FREEDESKTOP_MIME_TYPES_PATH 2.0\data\freedesktop.org.xml.in
- Refresh
刷新
- ，最后是gem install rails -v rails

- windows 10 ruby : 2.5.8
我从https://gitlab.freedesktop.org/xdg/shared-mime-info/下载了软件包，然后将环境变量(Windows) FREEDESKTOP_MIME_TYPES_PATH设置为该路径("c:....\data\freedesktop.org.xml.in")。
我还安装了mime-types-data > gem install mime-types-data
起初，在关闭并再次打开终端后，它无法正常工作。
提示:如果您使用vscode，则需要重新打开vscode
- Mac
如果您使用的是macOS，请尝试以下操作
brew install shared-mime-info
bundle update mimemagic

问题是，模拟团队昨天修改了很多版本，现在你必须在你的发行版中安装https://rubygems.org/gems/mimemagic/versions -mime-info包。
我建议在windows中使用WSL进行rails开发，这将在未来省去很多问题。
