Cài đặt `numpy` trong một virtualenv trong Ubuntu 11.10

Question

Tôi nhận được các ngoại lệ sau khi cài đặt numpy sử dụng easy_install numpy, ai đó có thể giúp bạn? Cho dù tôi đang sử dụng pip hoặc easy_install, tôi cũng gặp vấn đề tương tự. Thật khó để hiểu chuyện gì đang xảy ra.

Answer 1

Có lẽ GCC không được cập nhật. Tôi vừa thực hiện một thành công apt-get upgrade gcc và numpy.

Answer 2

Bạn chỉ cần sử dụng lệnh này thay vì easy_install. Đã làm việc cho tôi

sudo apt-get install python-numpy python-scipy
