@arthur657834 thank you for the report and sorry for the inconvenience!
Can you tell how you installed scancode?
Did you use a release tarball? Or a pip install? did you had already a previous version installed? Any special reason why you used a sudo system install?

[arthur657834]

how:
sudo pip install scancode-toolkit

python --version
Python 2.7.5

uname -a
Linux 3.10.0-957.5.1.el7.x86_64 #1 SMP Fri Feb 1 14:54:57 UTC 2019 x86_64 x86_64 x86_64 GNU/Linux

i had not install scancode-toolkit before

@arthur657834 which exact version of which Linux distro do you run such that this can be reproduced in a VM? I feel like this is not directly a ScanCode issue per se, but rather a Linux issue in some other system package that installed six too.

Otherwise, can you try instead to use a release tarball at https://github.com/nexB/scancode-toolkit/releases/tag/v3.0.2 ?

Fetch https://github.com/nexB/scancode-toolkit/releases/download/v3.0.2/scancode-toolkit-3.0.2.tar.bz2 and extract. Then run your scancode command from within this extracted directory.

cat /etc/redhat-release
CentOS Linux release 7.6.1810 (Core)

use a release tarball, there did not occur the problem,thank you for you help!

At this stage we no longer depend on six directly... I assume this is no longer an issue. Closing.
