PIP安装tesseract-ocr：失败，退出状态2

Question

我一直试图安装Tesseract-ocr库很长一段时间。阅读许多与其他软件包相关的问题并给出解决方案，但都没有成功。

我认为问题是关于我的Microsoft Visual Studio。有下面给出代码中的错误：

错误：命令 'C：\ Program Files文件（x86）的\微软的Visual Studio 10.0 \ VC \ BIN \ x86_amd64 \ cl.exe时' 失败，退出状态2

我卸载，重新安装，更新和尝试了很多东西，但仍然没有工作:(

由于现在已经

考虑使用pytesseract，为我工作在Python的3.6：PIP安装pytesseract

如果遇到运行上面的命令直接安装它的问题，试试这个链接： http://www.lfd.uci.edu/~gohlke/pythonlibs/

使用“查找”工具来查找pytesseract和在目录中的下载，按住shift键并点击右键，你会得到一个选项，有打开命令窗口并运行：

PIP安装“文件名”

你也可以尝试下载的Tesseract-OCR从上面的链接就像我刚才解释执行安装离线。 从来没有完全弄清楚为什么，但一些安装失败时工作下载。希望有所帮助。
