Virtual Environment Installation¶

Assuming you have virtualenv and virtualenvwrapper, the OpenEye Python Toolkits can be installed by the following steps:

First create a new virtual environment:
```
$ mkvirtualenv oepython35
```

Pip install OpenEye Python Toolkits into the new environment:

(oepython35) $ pip install -i https://pypi.anaconda.org/OpenEye/simple OpenEye-toolkits

Or you can also pip install from a tarball downloaded from http://www.eyesopen.com/downloads.

(oepython35) $ pip install OpenEye-toolkits-python3-linux-x64-2019.4.2.tar.gz

Run the OpenEye example oecheminfo.py to verify the OpenEye Python Toolkits have been successfully installed:

(oepython35) $ oecheminfo.py
Installed OEChem version: 2.2.0 platform: linux-g++4.x-x64 built: 20190501

Warning

Setting the environment variable PYTHONPATH will override the path to the Python modules installed in a virtual environment. Make sure PYTHONPATH is not set when using a virtual environment.
