Setup requirements error

[dbcraig]

Had an issue (from within a fresh conda environment) running:

pip install -r requirements.txt

After successfully compiling packages installation ultimately failed with:

...
Installing collected packages: monty, regex, urllib3, requests, unidecode, ruamel.yaml, pydispatcher, tabulate, spglib, palettable, pymatgen, pycryptodome, pdfminer.six, python-crfsuite, cssselect, appdirs, DAWG, chemdataextractor, jmespath, botocore, s3transfer, boto3, smart-open, gensim, tqdm
  Found existing installation: urllib3 1.12
ERROR: Cannot remove entries from nonexistent file /xxx/.conda/envs/tshitoyan/lib/python3.6/site-packages/easy-install.pth

The solution was to re-run pip with the --ignore-installed option:

pip install --ignore-installed -r requirements.txt

Beyond that, everything installed and ran as expected.
Hope this saves some headaches for others.

Great work!

same issue as yours

solved by downgrade to python 3.6

solved by downgrade to python 3.6

plus, you need a vpn if you are in china, otherwise it will be very slow downloading process

I've added checking for Python 3.6 in #8. @vtshitoyan could you please review and merge?

@jdagdelen I am not sure this fixes the issue since it happens during the pip install -r requirements.txt?

I'm adding the --ignore-installed flag to the recommended setup steps so new users should hopefully avoid running into this. I'm closing this now since discussion seems to have resolved but feel free to reopen if you want to continue discussing this issue.
