将 OpenCV 与 PyInstaller 结合使用
Using OpenCV with PyInstaller
尝试使用 PyInstaller 创建 Python 程序的二进制可执行文件时出现错误。但是，config.py 文件似乎存在一些问题。如果我尝试导入 cv2，我会收到以下错误消息：
Traceback (most recent call last):
File "exec_test.py", line 1, in <module>
File "/Users/me/path/to/.env/lib/python3.7/site-packages/PyInstaller/loader/pyimod03_importers.py", line 627, in exec_module

ImportError: OpenCV loader: missing configuration file: ['config.py'].
Check OpenCV installation.
[10914] Failed to execute script exec_test
我正在使用以下代码：
import cv2
if __name__ == '__main__':
print("Hello, world!")
当我 运行 它与 Python 时完全没问题。
要编译可执行文件，我是运行ning:
pyinstaller --onefile local-processing/exec_test.py
当 PyInstaller 运行s 时，它有以下输出：

我在 macOS High Sierra 上使用 Python 3.7.2、OpenCV 4.0.1 版和 PyInstaller 3.4 版以及 virtualenv 16.3.0 版。如果有任何其他信息有帮助，请告诉我。
谢谢！
确保您的 OpenCV 和 Pyinstaller 版本是最新的：
pip install --upgrade opencv-python
pip install --upgrade pyinstaller
您也可以随时尝试全新安装。
获取python中cv2的路径，编译时添加：
import cv2
print(cv2.file) # /usr/local/lib/python3.6/dist-packages/cv2/python-3.6/cv2.so
/home:~$ pyinstaller --onefile --paths="/usr/local/lib/python3.6/dist-packages/cv2/python-3.6" main.py
不久前我遇到了同样的问题。
要在 Windows 上解决该问题，它非常相似。不同之处在于，您必须确保找到 pyinstaller 从中加载信息的正确文件夹，因为一旦您拥有 cv2 容器以外的其他实例，这就很棘手了。例如，在我的机器中，我只能在将路径传递为 --path=AppData\Local\pyinstaller\bincache00_py39_64bit\cv2 时解决它，在 pyinstaller 命令的末尾添加该标志，一切都应该正常工作。
