安装etetoolkit时出错。 使用anaconda进行安装时

Question

I followed the directions to install etetoolkit for mac.

# Install Minconda  (you can ignore this step if you already have Anaconda/Miniconda)
curl -L 'http://repo.continuum.io/miniconda/Miniconda3-latest-MacOSX-x86_64.sh' -o Miniconda3-latest-MacOSX-x86_64.sh
bash Miniconda3-latest-MacOSX-x86_64.sh -b -p ~/anaconda_ete/
export PATH=~/anaconda_ete/bin:$PATH;

# Install ETE and external tools 
conda install -c etetoolkit ete3 ete_toolchain

# Check installation
ete3 build check

I get an error when I run conda install -c etetoolkit ete3 ete_toolchain

Error:

UnsatisfiableError: The following specifications were found to be incompatible with the existing python installation in your environment:

• ete3 -> python[version='>=2.7,<2.8.0a0,>=3.5,<3.6.0a0,>=3.6,<3.7.0a0']
• ete_toolchain -> python[version='>=2.7,<2.8.0a0,>=3.5,<3.6.0a0,>=3.6,<3.7.0a0'

Answer 1

1. I ran the [package installer][2] for anaconda 3.7. (I don't think I actually had to do this.)
2. From terminal run: conda install python=2.7
3. Then conda install -c etetoolkit ete3 ete_toolchain

Then I verified this worked by running ete3 build check . In the results clustalo: MISSING displayed, but that's a new problem to solve.

UPDATE

The final problem was solved by running conda install -c etetoolkit ete3_external_apps

There is a type-o in the instructions given by ete3. Use this instead.
