Error during installation

[Former user]

Hi, I'm trying to install MAGeCK-VISPR following the instruction. I got this error message:

UnsatisfiableError: The following specifications were found to be in conflict: - mageck-vispr -> cutadapt -> python 2.7 - python 3.6 Use "conda info <package>" to see the dependencies for each package.

The python version on my computer (MAC OS X) is 3.6.0, and conda version is 4.3.11. I'm not sure what might be the issue. Thanks!

Do you use the Python 2 version of Miniconda? MAGeCK-VISPR needs the Python 3 version. You don't necessarily need to reinstall. You can also install MAGeCK-VISPR into an isolated environment like that conda create mageck-vispr --name mageck-vispr. Then, activate that environment with source activate mageck-vispr and the mageck-vispr command becomes available.

Hi, I used Python 3 version of Miniconda but got exactly the same problem. I don't understand why there's a conflict of Python 2.7 and python 3.6

Can you try to install into the separate environment as shown above. If it fails, please provide full output.

I had the same problem-seems it's not because I used the Python 2 version of Miniconda. But install separate environment solve the problem, thanks!
