I really spent a lot of time on it and I need to finish installing it ASAP, so please help me out! I really appreciate you guys help!!!

I'm also having installation errors, but my errors are more similar to those in #16 .

In your error logs, it looks like your version of OpenCV 2 is installed as a subdirectory in an installation of OpenCV 4, which could be causing the errors. In #16 and in my error logs, I have no references to OpenCV 4. It could help to try a clean install of OpenCV 2 without Open CV 4. I used Conda to install OpenCV 2 with $ conda install -c conda-forge opencv=2.4 .

Then again, I'm still having errors, so I may not be the best person to help 🐙
