Errors when installing qiime2-2019.10

Hi, I tried to install the QIIME2-2019.10 within a miniconda2 environment in the Linux centos x64 system. I have updated conda. however, I got the following errors when I run qiime --help,

It seems an environment-related issue, [Qiime2- 2018.11 doesn't work on](http://Qiime2- 2018.11 doesn’t work on). So I checked the env. I didn’t set the PYTHONPATH before, how can fix it ?

Hey there @Hank_Leo! Looks like the smoking gun is right here:

Python 2.7 shouldn’t be showing up in your QIIME 2 env at all, and is likely leaking in from somewhere else (as you mentioned, this seems to be an environment-related issue - I agree).

The $PYTHONPATH that is currently set appears to be full of QIIME 1 related stuff… does that bring back any memories?

Fixing it will likely require you to update the PYTHONPATH env var (and maybe others, too). This is moving outside of our ability to help though - is there a sysadmin for this machine that you can work with? The environment seems to be very heavily customized (and some of those customizations don’t look like they will play well with other tools) - I am worried that if you start changing things you might bring this whole thing crashing down.

Keep us posted…

I am not sure for qiime1 memories, cause I use this server for the first time.
Can I delete the file /opt/qiime to fix ?

I would check with whoever administers this server, first.
