Python 如何修复使用conda后依赖关系不一致的环境；更新；命令？

我正在尝试更新Spyder以修复Spyder 3.2.3中的一些错误

但是当我调用（）中提到的

conda update spyder

时，Anaconda提示符显示如下：

Spyder也没有更新到最新版本（3.3.3）。 我猜我不能更新Spyder的原因是因为我的Conda不是最新版本，所以我跑了

conda update-n base-c默认值conda

但是在那之后（将conda更新到最新版本4.6.11），我发现我的Spyder和Anaconda Navigator都无法打开。看起来这些命令不仅更新了Conda，还将其他一些包更新为py3.7

当我再次调用

conda update spyder

时，提示如下：

我想可能是python版本冲突（我的python版本是3.6.2）导致了Spyder和Navigator的异常。因此，我尝试通过调用

conda install python=3.6

将这些包恢复到py3.6版本，但它不起作用

这是

conda list-version

（最后2版）的结果

这是康达信息的结果

解决此问题的最佳方法是什么

如何使Spyder重新工作？

幸运的是，我使用命令“conda install--revision 2”修复了Spyder，并在Anaconda Navigator中将Spyder更新为3.3.4版

conda列表--version

可以显示之前的每个版本，因此我使用命令

conda install--version 2

将环境恢复到更新conda之前的状态。之后，我的Spyder和Anaconda Navigator就可以正常使用了。然后我将Anaconda Navigator中的Spyder更新为3.3.4版

这是

的链接。我重新安装了导致不一致的软件包，然后问题就消失了

我的不一致错误：

我所做的：

conda install -c conda-forge mkl-service

---

这适用于python3.8和spyder4.1.5：

conda install pyqt --force-reinstall

你真的需要优先考虑你的大学频道吗？看起来它为您提供了很多旧包，因为它具有优先权，所以您正在解决您的依赖关系。我建议将其移动到频道顺序中的最低优先级。感谢您的建议，这是我唯一的频道选择，除了使用VPN。幸运的是，我已经使用命令“conda install--revision 2”修复了Spyder，并在Anaconda Navigator中更新了Spyder。
