I am trying to create an environment for an installation (https://github.com/linzhi2013/MitoZ/), but I get the following error. Any suggestions what I need to install/uninstall to make it work?

:~$ conda create  -n mitozEnv libgd=2.2.4 python=3.6.0 biopython=1.69 ete3=3.0.0b35 perl-list-moreutils perl-params-validate perl-clone circos=0.69 perl-bioperl blast=2.2.31  hmmer=3.1b2  bwa=0.7.12 samtools=1.3.1 infernal=1.1.1 tbl2asn openjdk

Take it one step at a time.

  1. Why are you specifying a fixlevel 3.6.0 for Python? Unless you have a very good reason, relax this to python=3.6. Newer fixlevels might work with different versions of tk, which could resolve some of your problems.
  2. blast 2.2.31 drags in a dependency on Python 3.5 via boost 1.60. Relax the version of blast, so you can pull in a version of boost that works with the Python 3.6 you want.

With those changes, try again and see what problems remain.
