After creating a test environment with annaconda: conda create -n test python=3.8, install conan: pip3 install conan==1.41.0, enter conan to test whether it is available, and report an error: ImportError: cannot import name 'soft_unicode' from 'markupsafe'
Conda list shows that the previous version of markuosafe is 1.1.1
Solution: pip install markupsafe==2.0.1
Conan shows normal again
