#Python #爬虫 #安装库

在Mac上安装tesseract和tesserocr库时遇到错误，通过Google搜索和Github上的解决方案，最终使用特定的CC、XCC和CPPFLAGS环境变量成功安装tesserocr。然而，即使安装成功，在Python环境中导入tesserocr时仍然会报错。通过设置locale为'C'，可以避免运行时错误并正常运行代码。

问题描述

学习Python爬虫首先要配置环境安装tesseract和tesserocr两个库，但是在Mac上按照书中的指导会出现无法解决的安装错误，经过一天时间的试错，总算把这两个库安装完毕可以使用。

解决方法

tesseract&tesserocr安装指南

1.安装tesseract

终端输入指令brew install tesseract

在安装全语言支持版本的时候，指令为brew install tesseract-lang

验证所支持的语言，指令为tesseract --list-langs

2.安装tesserocr

终端输入指令

采用指令：

pip3 install tesserocr pilow
