解决conda报错：Error while loading conda entry point: conda-libmamba-solver (No module named 'libmambapy.bindings')

最近使用conda 突然出现了这个问题：

Error while loading conda entry point: conda-libmamba-solver (No module named 'libmambapy.bindings')

网上看了很多方法，尝试后都没有解决。

 

最后，在执行以下命令时， conda config --set solver classic，出现了以下报错信息：
Error while loading conda entry point: conda-libmamba-solver (No module named 'libmambapy.bindings')
Error while loading conda entry point: conda-libmamba-solver (No module named 'libmambapy.bindings')
/home/XXX/software/pymol3.1.3/pymol/lib/python3.10/site-packages/conda_package_streaming/package_streaming.py:25: UserWarning: zstandard could not be imported. Running without .conda support.
  warnings.warn("zstandard could not be imported. Running without .conda support.")

？？怎么会有pymol呢，于是突然想起来前一段时间我将 PyMOL 的模块路径添加到 PYTHONPATH中去了，见 https://www.cnblogs.com/jszd/p/18882244

于是，赶快将环境变量中的

export PYTHONPATH=$PYTHONPATH:/home/username/software/pymol3.1.3/pymol/lib/python3.10/site-packages

隐藏掉，

问题解决！
