python - conda 4.9.2 是否报告假包冲突？

Question

自从更新了我的 Anaconda 基础架构，包括更新 conda到 v4.9.2，我发现安装了我的一个软件包:pybert ， 被打破。 而且，当我细读报告的冲突列表时，我看到如下内容:

Package six conflicts for:
chaco -> enable[version='>=4.8.0,<4.9'] -> six
scikit-rf -> six

这在我看来是假的。 (两条路径都通向six，没有版本限制；所以，怎么会有冲突？)

我是误读了这些冲突报告，还是 conda又坏了？

谢谢!

回复@merv(谢谢!)，这是我的 conda install ... 的完整输出命令:

下面是该输出中提到的每个“冲突”包的版本，我相信它们满足所有家属的要求:

<表类="s-表"> <头> 打包 版本 构建 <正文> 赛通 (任意) (任意) numpy 1.19.2 (任意) gdbm 1.18 (任意) 设置工具 18.5 (任意) ca 证书 (任意) (任意) matplotlib-base 2.1.2 (任意) libpng 1.6.35 (任意) libcxxabi 4.0.1 hcfea43d_1 六个 (任意) (任意) kiwisolver 1.0.1 (任意)

我很好奇:是否有人阅读本文不同意我在上面声明的任何工作版本？ (我还在想我是不是不太明白如何解释这个输出。)

根据我自己的经验，在这里，以及我在搜索该主题时发现的内容，似乎很可能 conda在这方面目前已被打破(即 - 识别真正的冲突)。 谁是合适的人来讨论帮助解决这个问题？

谢谢!

Answer 1

问题原来是 parsec 包被锁定到 Python 3.7，而其他所有东西都要求 3.8。 我不知道为什么 conda 没有在其“冲突”报告中以某种明显的方式报告这一点。
