Question

我正在尝试更新Spyder，以修复Spyder 3.2.3中的某些错误。

但是当我打电话给https://github.com/spyder-ide/spyder/issues/9019#event-2225858161中提到的conda update spyder时，Anaconda提示符显示如下：

enter image description here

，并且Spyder尚未更新为最新版本（3.3.3）。我猜我无法更新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 defaults conda

但是在那之后（将conda更新到最新版本4.6.11），我发现无法打开我的所有Spyder和Anaconda Navigator。看来，这些命令不仅更新了Conda，而且还将其他一些软件包更新到py3.7。

当我再次致电conda update spyder时，提示如下：

我想也许python版本冲突（我的python版本是3.6.2）导致Spyder和Navigator异常。因此，我尝试通过调用conda install python = 3.6将这些软件包恢复到py3.6版本，但是它不起作用。

这是conda list -version（最近的2转）的结果

解决此问题的最佳方法是什么？

如何让Spyder重新工作？

Answer 1

幸运的是，我已经使用命令'conda install --revision 2'修复了Spyder，并在Anaconda Navigator中将Spyder更新到了3.3.4版本。

conda install --revision 2可以显示以前的每个修订版，因此我使用命令{{1}}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，在Anaconda Navigator中将我的Spyder更新到版本3.3.4。

这是conda install

的链接

Answer 2

这适用于python3.8和spyder4.1.5：

conda install pyqt --force-reinstall

Answer 3

我重新安装了导致不一致的软件包，然后问题消失了。

我的不一致错误：

我做了什么：

conda install -c conda-forge mkl-service

使用conda“ update”命令后，如何使用不一致的依赖项修复环境？
