确定 Anaconda XZ 包装内容

Question

我目前正在尝试找出 anaconda package called XZ 的内容。

据我了解，该包为XZ Utils (data compression tool) 提供绑定。

我试图找出包中存在的 XZ Utils 的组件，它是否只有 liblzma 库，或者它也有命令行工具和 shell 脚本。有人可以帮我解决这个问题吗？

非常感谢您抽出宝贵时间:)

尝试的方法

我尝试从环境的 conda-meta 文件夹中查看 XZ 包 json 文件。我相信 conda-meta 文件夹包含每个安装包的元数据。

json文件内容如下。

}

从“文件”部分，我相信它告诉了包提供的文件。它确实声明它有 liblzma 库。它还显示“xz.exe”，我认为它可能是命令行工具，但我不能保证。

动机

就上下文而言，我实际上是在尝试避免使用 gpl 许可软件。从文档中，它指出different licenses are applied to different parts of xz utils。稍微研究了一下，python其实已经有了buildin binding to liblzma，所以我有点想知道这个包提供了什么。

Answer 1

是的，files: 部分列出了将安装到环境中的文件。 bin/ 下的那些是可执行程序，lib/ 是共享库，include/ 是用于编译的头文件。

Answer 2

我找到了与我的问题相对应的issue on XZ conda-forge package's repo。

我在my question on the open source stack exchange 上发布了更多相关信息。

总之，包中不存在“grep、diff、查看压缩文件的脚本”组件。

不过，命令行组件的问题仍然存在。
