ERROR: Could not install packages due to an OSError: [[Errno 22] Invalid argument: '/tmp/pip-req-build]

Question

I'm using the Win10 built-in linux system and type pip install -U . and then I got a terrible error:

ERROR: Could not install packages due to an OSError: [('/mnt/f/MyDownloads/Download/cactus-bin-v1.2.3/.git/branches', '/tmp/pip-req-build-luuzar9x/.git/branches', "[Errno 22] Invalid argument: '/tmp/pip-req-build-luuzar9x/.git/branches'"), ('/mnt/f/MyDownloads/Download/cactus-bin-v1.2.3/.git/hooks', '/tmp/pip-req-build-luuzar9x/.git/hooks', "[Errno 22] Invalid argument: '/tmp/pip-req-build-luuzar9x/.git/hooks'"), ('/mnt/f/MyDownloads/Download/cactus-bin-v1.2.3/.git/info', '/tmp/pip-req-build-luuzar9x/.git/info', "[Errno 22] Invalid argument: '/tmp/pip-req-build-luuzar9x/.git/info'"), ('/mnt/f/MyDownloads/Download/cactus-bin-v1.2.3/.git/logs/refs/heads', '/tmp/pip-req-build-luuzar9x/.git/logs/refs/heads', "[Errno 22] Invalid argument: '/tmp/pip-req-build-luuzar9x/.git/logs/refs/heads'"), ('/mnt/f/MyDownloads/Download/cactus-bin-v1.2.3/.git/logs/refs/remotes/origin', '/tmp/pip-req-build-luuzar9x/.git/logs/refs/remotes/origin', "[Errno 22] Invalid argument: '/tmp/pip-req-build-luuzar9x/.git/logs/refs/remotes/origin'"), ('/mnt/f/MyDownloads/Download/cactus-bin-v1.2.3/.git/logs/refs/remotes', '/tmp/pip-req-build-luuzar9x/.git/logs/refs/remotes', "[Errno 22] Invalid argument: '/tmp/pip-req-build-luuzar9x/.git/logs/refs/remotes'"), ('/mnt/f/MyDownloads/Download/cactus-bin-v1.2.3/.git/logs/refs', '/tmp/pip-req-build-luuzar9x/.git/logs/refs', "[Errno 22] Invalid argument: '/tmp/pip-req-build-luuzar9x/.git/logs/refs'"), ('/mnt/f/MyDownloads/Download/cactus-bin-v1.2.3/.git/logs', '/tmp/pip-req-build-luuzar9x/.git/logs', "[Errno 22] Invalid argument: '/tmp/pip-req-build-luuzar9x/.git/logs'"), 

I use python3.6 and the built-in linux system is just called out. I really don't know why I got such an error.

Answer 1

have you tried upgrading your python version? you can do that in windows from Add/remove programs or if you have chocolatey: from you powershell (open as admin) simply run:

choco upgrade python

In linux you can do so by running (depending on your distribution, you might need to use yum or dnf instead of apt):

apt update
apt upgrade python

You might want to add sudo in front of the command if you are not root(admin). I hope this solves your problem.
