Pip install tesseract-ocr：失败，退出状态为 2

Question

我一直在尝试安装 Tesseract-ocr 库。阅读许多与其他包相关的类似问题和给定的解决方案，none 有效。

我认为问题出在我的 Microsoft Visual Studio 上。以下代码出现错误：

error: command 'c:\Program Files (x86)\Microsoft Visual Studio 10.0\VC\Bin\x86_amd64\cl.exe' failed with exit status 2

我卸载、重新安装、更新并尝试了很多东西，但仍然无法正常工作:(

谢谢了！

Answer 1

考虑使用 pytesseract，在 python 3.6 上为我工作：pip install pytesseract

如果您通过运行ning 上述命令直接安装它时遇到问题，请尝试此 link： http://www.lfd.uci.edu/~gohlke/pythonlibs/

使用 "find" 工具找到 pytesseract 并在其下载的目录中，按住 shift 键并单击鼠标右键，您将看到一个选项可以打开命令 window 和运行 :

pip 安装"filename"

您也可以尝试从上面的 link 下载 tesseract-ocr 并像我刚才解释的那样离线执行安装。从来没有完全弄清楚为什么，但是一些失败的安装在下载时有效。希望有所帮助。
