You are in 'detached HEAD' state. You can look around, make experimental
changes and commit them, and you can discard any commits you make in this
state without impacting any branches by performing another checkout.

If you want to create a new branch to retain commits you create, you may
do so (now or later) by using -b with the checkout command again. Example:

git checkout -b

hi , what is your version of pip? Upgrade your version to 21.1.1 and it will be ok.

@zhouzaida, this error still there, and I have found the solution: update the versions of Click library:

mim/setup.py

Line 32 in faf51cb

'Click==7.1.2',

and this version is not work, it should be remove from setup.py
