[转载]Error: invalid option: --with-training-tools

导语：

这个错误相信是不少人安装tesseract的时候要开始训练ocr识别的时候会报的一个错误。你想安装训练工具就会提示告诉你没有--with-training-tools这个参数。找了好久，最后在网上找到一篇博客说要编译安装才行。这篇博客的内容就是把我找到的那边博客的内容复制了一遍，之因此这样作是为了其余人遇到该问题的时候能更容易找到这个解决方式，毕竟多一篇blog答案就更容易找到，若是这篇文章对你有帮助的话，仍是请移步到原做者那边查看吧。原文地址git

解决方式：
1.安装依赖github

# Packages which are always needed.
brew install automake autoconf libtool
brew install pkgconfig
brew install icu4c
brew install leptonica

# Packages required for training tools.
brew install pango

# Optional packages for extra features.
brew install libarchive

# Optional package for builds using g++.
brew install gcc
复制代码

2.下载解压tesseract-4.1.1.tar.gz github.com/tesseract-o…markdown

3.编译安装工具

cd tesseract-4.1.1
./autogen.sh
mkdir build
cd build

# Optionally add CXX=g++-8 to the configure command if you really want to use a different compiler.
../configure PKG_CONFIG_PATH=/usr/local/opt/icu4c/lib/pkgconfig:/usr/local/opt/libarchive/lib/pkgconfig:/usr/local/opt/libffi/lib/pkgconfig
make -j

# Optionally install Tesseract.
sudo make install

# Optionally build and install training tools.
make training
sudo make training-install
复制代码

4.下载eng.traineddata github.com/tesseract-o…oop

5.测试测试
