【中文标题】pip install tesserocr 失败并出现错误“tesserocr 构建***失败”【英文标题】：pip install tesserocr fails with error " Failed building wheel for tesserocr" 【发布时间】：2017-09-05 02:10:05 【问题描述】：我已经有了 leptonica 和 tesseract 的最新版本
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
我还安装了所有依赖项，例如 python-dev
这是我在我的中执行 pip install tesserocr 时遇到的错误 虚拟环境

【问题讨论】：
您找到解决方案了吗？ 如果您运行的是 ubuntu 14.04，请尝试从源代码构建 tesseract 3.04，它对我有用 试过了，但是没用。 【参考方案1】：终于解决了问题
从系统中完全移除 tesseract 和 leptonica 并从源代码构建所有内容
ubuntu 14.04 的 debian 包 leptonica-dev 是问题
这些是我编译的当前版本
$ 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
