Rails错误找不到freedesktop.org.xml

Question

我在开始一个新的RAILS项目时遇到了一些问题，我得到了一个错误，说缺少文件/usr/local/share/mime/packages/freedesktop.org.xml。这与模仿依赖有关，我在GitHub上发现了这个关于模仿版本和许可的问题-- https://github.com/rails/rails/issues/41750

想知道是否有其他人遇到了这个问题，并可以解释发生了什么。

我使用的是rbenv和ruby版本: 3.0.0p0 (2020-12-25修订版95aff21468) x86_64-darwin19和rails 6.1.3

以下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.

在我发布的GitHub链接上找到了一些指向shared-mime-info的链接，我通过运行以下命令并启动一个新项目解决了这个问题：

brew install shared-mime-info

如果你在ubuntu操作系统上，你可以运行下面的命令

sudo apt-get install shared-mime-info
