无法在项目环境中安装spyder

Question

我成功地在anaconda安装了fenicsproject。但是，我无法在此环境中安装spyder

我在fenicsproject环境中运行了conda install spyder，从终端收到了这条很长的消息。我真的不知道如何着手修理它

UnsatisfiableError: The following specifications were found

Your python: python=3.8

If python is on the left-most side of the chain, that’s the version you’ve asked for.
When python appears to the right, that indicates that the thing on the left is somehow
not available for the python version you are constrained to. Note that conda will not
change your python version to a different minor version unless you explicitly specify
that.

The following specifications were found to be incompatible with each other:
