Xây dựng OpenCV_Python trong Mac OS X 10.9 bằng homebrew

Question

Tôi đang cố gắng cập nhật OpenCV của mình từ phiên bản 2.4.5 lên phiên bản 2.4.6.1 bằng cách sử dụng homebrew. Khi tôi chạy brew upgrade opencv
tôi chạy vào báo lỗi sau:

Có vẻ như bị thất bại khi xây dựng bindings Python của OpenCV. Tôi đã cài đặt phiên bản Java 1.7.0_45-b18 trên máy Mac của mình và cài đặt Python 2.7.5 trên hệ thống cùng với Numpy 1.7.1. Tôi đã tự hỏi điều gì sẽ là vấn đề ở đây.

Tiếp tục gỡ rối cho thấy rằng vấn đề này là do khi xây dựng OpenCV_Python và đây là lỗi nơi xây dựng dừng:

thể ai vui lòng giúp đỡ xây dựng OpenCV?

Answer 1

Bạn có thể gặp phải lỗi trình biên dịch xung quanh các hàm Py * vì nó không thể tìm thấy python bao gồm trong các thư mục tìm kiếm của nó.

Tôi sẽ không dựa vào việc xây dựng python kho và đề xuất cài đặt phiên bản khác thông qua python. Cả hai bản xây dựng python đều có thể cùng tồn tại trên cùng một máy, nhưng tốt hơn là bạn nên dựa vào cài đặt của brew. Bạn có thể xác minh nó bằng cách kiểm tra xem "con trăn" nào trỏ tới/usr/local/bin/python hoặc từ phiên bản khi bạn khởi động trình thông dịch python. Nhận xét của GilberLee chỉ ra một số bước tốt để thiết lập điều này: Installing openCV 2.4.2 on Mac OS X 10.9 (Mavericks)

Sau khi cài đặt homebrew homebrew, hãy thử cài đặt lại opencv và xem bạn có vượt qua những lỗi biên dịch đó không.
