我在启动一个新的 RAILS 项目时遇到了一些问题，我收到了一个错误，即缺少文件/usr/local/share/mime/packages/freedesktop.org.xml。与 mimemagic 依赖项有联系，我在 GitHub 上发现了这个关于 mimemagic 版本和许可的问题 - https://github.com/rails/rails/issues/41750

想知道是否有其他人遇到过这个问题，并可以解释发生了什么。

我正在使用带有 ruby​​ 版本的 rbenv：3.0.0p0（2020-12-25 修订版 95aff21468）[x86_64-darwin19] 和 rails 6.1.3

这是命令行中的错误消息：

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

Tasks: TOP => default
(See full trace by running task with --trace)

rake failed, exit code 1

谢谢，尼科

Found some links to shared-mime-info on the GitHub link I posted, and I solved the issue by running the command below and starting a new project:

brew install shared-mime-info

如果您使用的是 ubuntu 操作系统，则可以运行以下命令

sudo apt-get install shared-mime-info

如果将数据从 Intel Mac（或运行 Rosetta 2 的 M1 Mac）迁移到 M1，请注意 mimemagic 将缓存旧目录，因此除了brew install shared-mime-info，您还需要运行：

gem uninstall mimemagic
gem install mimemagic
