我在尝试使用 conda 安装 mayavi 时遇到了一些问题。首先它被困在“解决环境”步骤中，然后我得到了这个
(base) usr@pc:~$ conda install -c anaconda mayavi

UnsatisfiableError: The following specifications were found
to be incompatible with the existing python installation in your environment:
Specifications:
- mayavi -> python[version='>=2.7,<2.8.0a0|>=3.6,<3.7.0a0|>=3.7,<3.8.0a0']
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.
我对这条消息有点困惑，“如果python在链的最左边”是什么意思？我还修改了我的 PATH 并且我使用的是 python 3.8，安装不应该使用最新版本吗？
