pycharm 打开摄像头失败

环境 pycharm2019.2，python3.7 ，Mac OS X10.14

import cv2

cap = cv2.VideoCapture(0)

while True:
    ret, frame = cap.read()
    cv2.imshow("Video", frame)
    if cv2.waitKey(1) == 27:
        break

cap.release()
cv2.destroyAllWindows()

报错
/usr/local/bin/python3.7 "/Users/pig/学习/编程练习/Pycharm/Python 2.7/cv_test/test11.py"

Process finished with exit code 134 (interrupted by signal 6: SIGABRT)

代码是ok的。我打开摄像头正常！ 你确定你cv环境ok?

同样的问题，目前可以确定是pycharm没有请求摄像头权限，直接在终端用python调脚本是可以正常打开的
