Cannot install on python2.7. "Command "python setup.py egg_info" failed with error code 1"

[nehagupta93]

I ran pip install formulas[all]
And got the following output:
`Traceback (most recent call last):
File "", line 1, in
File "/tmp/pip-install-G63Y__/formulas/setup.py", line 62, in
proj_ver = read_project_version()

File "", line 0
SyntaxError: encoding declaration in Unicode string

Command "python setup.py egg_info" failed with error code 1 in /tmp/pip-install-G63Y__/formulas/`

Things that I have tried which did not work (with and without sudo access, in and outside the virtual environment):

• sudo pip install --upgrade setuptools
• sudo apt-get install libmysqlclient-dev
• pip install --upgrade pip
• pip install formulas

I also tried installing it by cloning the repository and running the setup.py file.

The error does not occur with python3. My project only runs on 2.7. Does this repository only support python3?

I'm sorry but this library supports for the moment support the following python versions:

formulas/setup.py
