今天遇到了这个问题。发生这种情况是因为我们缺少这些库

libleptonica-dev 和 libtesseract-dev

解决方案是使用您的包管理器安装它们。

  • Ubuntu
    • apt-get install libleptonica-dev libtesseract-dev
  • 苹果电脑
    • pip install tesserocr
      • 将自动安装tesserocr及其依赖库leptonica

解决了这个问题

我的错误是这样的:

我通过额外安装pkg-config库解决了这个问题。

apt-get install libleptonica-dev libtesseract-dev \
    tesseract-ocr tesseract-ocr-eng \
    pkg-config

如果您使用的是 linux(基于 Debian,例如 Ubuntu 14.04)系统,您想升级您的 Tesseract 版本。显然,在 Ubuntu 14.04 中,默认 Tesseract 版本是 3.03,tesserocr 不支持该版本。您必须使用一些较新的 Tesseract 版本(如 4.00 或 3.05)从源代码构建。但在较新的操作系统版本中,这应该不是问题。

只需按照
安装链接使用 Tesseract 3.04+ 安装 Tesserocr
