Question

我在Mac上安装了Python和Anaconda两个版本，分别是3.5和3.7。有没有办法知道我在3.5中安装了哪些软件包而不是3.7中的软件包，例如可以使用pip安装的软件包（纸浆，wordcloud等）。

到目前为止，我一直在尝试使用命令行：

DB::connection('database_name')->query

这显示了目录之间的差异，但显示了许多重复包和核心模块的信息。如何找到两个Anaconda版本之间的软件包差异？

Answer 1

您可以使用conda list列出在特定环境下安装的所有软件包。另外，您可以将列表导出到带有标志--export的文件。例如，如果您的环境分别命名为python3和pytorch_p36，则可以执行以下操作：

conda list -n python3 --export > python3-packages.txt
conda list -n pytorch_p36 --export > pytorch_p36-packages.txt
diff python3-packages.txt pytorch_p36-packages.txt

该命令还接受标志--json，该标志将以json格式导出数据，适用于自动处理。

Answer 2

感谢dataista为您的Linux解决方案。对于Windows差异无法正常工作，但是在 Windows 中，可以使用 FC ：

conda list -n python3 --export > python3-packages.txt
conda list -n pytorch_p36 --export > pytorch_p36-packages.txt
FC python3-packages.txt pytorch_p36-packages.txt

Answer 3

现在，最近的一项开发提供了将conda环境与需求文件进行比较的功能。到目前为止，我发现的唯一提及内容是在2020年7月16日合并的pull request中。我可以验证compare命令在conda版本4.8.4中有效。应该注意的是，输出中仅列出了差异。

用法：
