Question

有人可以帮助我了解应该如何阅读吗？每当我收到Conda的依赖关系解决错误时，我都会不得不做一些基本的调查，因为错误消息（尽管看起来确实是在尝试提供帮助）基本上感觉毫无用处。

很乐意更好地了解我应该如何阅读。

Answer 1

Package libffi conflicts for:
python=3.7 -> libffi[version='>=3.2.1,<3.3.0a0|']

我认为这意味着您正在尝试安装python 3.7，它要求libffi版本为> = 3.2.1和<3.3.0a0（或> = 3.2.1和< 4.0a0）。但是，您过去安装的libffi版本必须在此兼容版本范围之外（例如，您要求版本<3.2）。

也许发布生成错误的命令和conda list的输出（假设您正在尝试在当前环境中安装/升级）。
