【问题讨论】：
【参考方案1】：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
解决方案是使用包管理器安装它们。
Ubuntuapt-get install libleptonica-dev libtesseract-dev
Mac
pip install tesserocr
将自动安装tesserocr 及其依赖库leptonica
解决了问题
【讨论】：
按照我的建议，您遇到了什么问题/错误，您的平台是什么？ 我在 cloud9 上使用 ubuntu。请参阅上面的更新错误。 尝试安装 python-dev 包，也许你缺少标题 如果安装上述库没有帮助，请同时安装 pkg-config - 它对我有用。 这对我也有帮助，谢谢！【参考方案2】：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
【讨论】：
【参考方案3】：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。
