导入错误：dlopen（/Users/Desktop/myapp/target/myapp_mac/cv2/cv2.cpython-36m-darwin.so，2）

我在MacOS中使用Pyinstaller和OpenCV。在构建独立应用程序之后，我得到以下错误。我尝试过不同版本的模块，但都不管用

我正在使用

• MacOs版本：10.14.5
• python:3.6
• pyinstaller:3.4
• opencv python:3.4.5

错误：

简而言之，根据您的项目，尝试使用包

opencv-python-headless

而不是

opencv-python

我只是让它为我自己工作。问题似乎在于包

opencvpython

链接到了Qt4，py安装程序从PySide2复制了Qt5二进制文件，因此无法找到符号

您使用的是哪个版本的qt，以及哪个绑定，PySide2或PyQT5？我有一个确切的错误，我正在努力找出它。应用程序运行，但被PyInstaller冻结时不会运行。您使用的是哪个版本的Qt，以及哪些绑定，PySide2或PyQT5？我有一个确切的错误，我正在努力找出它。应用程序运行，但在PyInstaller冻结时不运行
