Workaround memo when Segmentation fault: 11 appears in import of opencv that was brew installed with virtualenv of python

Reference: Using OpenCV with Python @Mac --Qiita

According to the above, under site-packages of my virtualenv, cv.py and cv2.so I put a symbolic link, but when I ʻimport cv`, ** "Segmentation fault: 11" ** came out and fell. UU….

In virtualenv,

After doing brew uninstall opencv I did brew install opencv

Traceback (most recent call last):
  File "<string>", line 1, in <module>
AttributeError: 'module' object has no attribute 'getusersitepackages'

The error is.

I didn't feel like I could go straight, so I went to ~ / .bashrc.

# python
export PYTHONPATH=/usr/local/lib/python2.7/site-packages:~/.virtualenvs/my_venv/lib/python2.7/site-packages:$PYTHONPATH

After adding and doing brew install opencv again, this time the above error did not appear.

Launch python with source ~ / .bashrc

import cv
import cv2

After that, there was no segfault. It was a memo. .. ..

(For the time being, anyenv → talk under the environment of pyenv)

If it still doesn't work

ʻEcho'import site; site.addsitedir ("/ usr / local / lib / python2.7 / site-packages ")' >> ~ / .pyenv / versions / {virtualenv_name} /lib/python2.7/site-packages Try /homebrew.pth` (No, maybe you should do it from the beginning).
