我正在尝试在 Ubuntu 上安装 python3.6 的 tesserocr 包。当我运行pip3 install tesserocr时，我收到此错误:

Answer 1

谢谢大家，我已经解决了。我从 git 下载 tesserocr 源文件并运行:

henry@PC:~/tesserocr$ pip3 install .
Processing /home/henry/tesserocr
Installing collected packages: tesserocr
  Running setup.py install for tesserocr ... done
Successfully installed tesserocr-2.2.2

花了很多时间，但终于成功了。看来tesserocr的pip源与最新的tesseract-ocr不匹配，需要手动安装。
