Not able to build language-check using setuptools in python2.7.

[sjose1x]

from setuptools import setup, find_packages setup( name='name', version='0.0.1', description=' TA', long_description=DESCRIPTION, license='Proprietary License', author='', author_email='', packages=find_packages(), install_requires=[ "language-check==0.7.1", "3to2==1.1.1", ],

python setup.py install #Fails

I don't use Python 2, but as far as I know, 3to2 must be installed beforehand. Only then can you install language-check. Otherwise, setup.py won't have access to 3to2.

$ pip install 3to2
$ pip install language-check

As far as I know, this is just how 3to2 works. Below is an example from another (unrelated) project.

(python2.7)
$ pip install git+https://github.com/JelteF/PyLaTeX

I suggest you report this upstream in the 3to2 issue tracker.

On a related note, I would be willing to merge a pull request that converts this code to be Python 2 compatible in addition to Python 3. This would remove the need for 3to2.
