Missing "module named req"

[kmdowney12]

I'm installing Blobtool v1.0 and I keep getting this error thrown back at me following the ./install command.

[+] Checking dependencies... [+] [wget] /usr/local/bin/wget [+] [tar] /usr/bin/tar [+] [pip] pip [+] [python2.7] /Users/kdowney/anaconda3/envs/blob_tools/bin/python [+] Installing python dependencies... Traceback (most recent call last): File "setup.py", line 4, in from pip.req import parse_requirements ImportError: No module named req FAIL.

What can I do to fix this? There are some tips online, but when I modify your code as they recommend, other pieces start failing.

Also, I'm doing this on a Mac if that matters.

Hi,

sorry for not answering earlier ...

I guess you already noticed that this was caused by your python being python3 instead of python2...

cheers,

Hi Dom,

Nope, my python was fine. We just switched it over to our Linux machine instead. Works fine there. Thanks though!

Ahso, ... I thought the anaconda3 in your python path meant it was a python3 environment.

let me know if you run into any other problems.

cheers,

Hallo @DRL, I also had this issue using pip 18.0 with python 2.7.15 on Debian 9.5 (stretch)

~/blobtools> which pip
/usr/local/bin/pip
~/blobtools> /usr/local/bin/pip --version
pip 18.0 from /usr/local/lib/python2.7/site-packages/pip (python 2.7)
~/blobtools> which python
/usr/local/bin/python
~/blobtools> /usr/local/bin/python --version
Python 2.7.15

It looks like from pip.req import parse_requirements doesn't work with pip > 10, see: https://stackoverflow.com/a/49867265

Workaround is to downgrade to pip 9 e.g.

python -m pip install pip==9.0.3

Cheers!
