Hi, I faced the problem exactly the same as yours. I tried to install PyYAML 5.1 but failed.

ERROR: Cannot uninstall 'PyYAML'. It is a distutils installed project and thus we cannot accurately determine which files belong to it which would lead to only a partial uninstall.

Could you give some insight? Thanks!

I‘ve installed ruamel.yaml and updated PyYAML v5.1. And it works.

pip install PyYAML==5.1

or you can try ’wget‘ to update.

Hi, @danieasv @DorisHX

I also faced this problem. I think its sth about the yaml lib which may relate to pip install ruamel.yaml. I also tried pip install PyYAML ==5.1 but it said ERROR: Invalid requirement: '==5.1'. Personally i have both py2 and py3. Though i pip installed the above lib, it still didnt work.

Looking forward to your help. THANKS

pip install PyYAML ==5.1 ,it seems there should not a space betwwen 'PyYaml' and '==‘.
