pips cài đặt tesserocr thất bại với lỗi "bánh xe xây dựng Không cho tesserocr"

Question

Tôi đã có xây dựng mới nhất cho leptonica và Tesseract

tesseract 4.00.00alpha-365-gcf0b378 
leptonica-1.74.1 
    libjpeg 8d (libjpeg-turbo 1.3.0) : libpng 1.2.50 : libtiff 4.0.3 : zlib 1.2.8 

tôi cũng đã cài đặt tất cả phụ thuộc như python-dev

Lỗi này tôi nhận được khi tôi cài đặt pip tesserocr trong số virtualenv

Answer 1

Cuối cùng cố định vấn đề này

Tesseract loại bỏ hoàn toàn và leptonica từ hệ thống và xây dựng mọi thứ từ nguồn

sự gói debian leptonica-dev cho ubuntu 14.04 là vấn đề

đây là những bản dựng hiện tại tôi đã biên soạn

$ tesseract -v 
tesseract 3.04.01 
leptonica-1.74.1 
    libjpeg 8d (libjpeg-turbo 1.3.0) : libpng 1.2.50 : libtiff 4.0.3 : zlib 1.2.8
