Hi there, 

Crosspost to the google group for ETE3: 

I'm trying to install etetoolkit (http://etetoolkit.org/) via conda on MacOS and keep getting the same error. Google has been of very little help unfortunately. I've also removed and reinstalled miniconda. 
As suggested on the website, I ran the following: 

    conda create -n ete3 python=3
    conda activate ete3
    conda install -c etetoolkit ete3 ete_toolchain

Then I get the following error indicating it cannot find python (weird):

    LinkError: pre-link script failed for package etetoolkit::ete3-3.0.0b35-py_0 
    location of failed script: /PATH/TO/miniconda3/pkgs/ete3-3.0.0b35-py_0/bin/.ete3-pre-link.sh

    ==> script messages <==
    <None>
    ==> script output <==
    stdout: 
    stderr: + /PATH/TO/miniconda3/envs/ete3/bin/python /PATH/TO/miniconda3/pkgs/ete3-3.0.0b35-py_0/link.py

    /PATH/TO/miniconda3/pkgs/ete3-3.0.0b35-py_0/bin/.ete3-pre-link.sh: line 2: /PATH/TO/miniconda3/envs/ete3/bin/python: No such file or directory
    return code: 127

I've tried putting python in the bin, but that did not solve the problem. 

Does anyone have any ideas on how to solve this? I've been using this tool for years with no problem, but it seems like something has gone awry with the latest versions. 

Thanks! Please let me know if I can provide more info.

EDIT -- SOLVED

Solved!! Try to install the two packages separately, this works!

    conda install -c etetoolkit ete3
    conda install -c etetoolkit ete_toolchain
