python爬虫---tesserocr库的安装

暑假放假第二天，打开了爬虫之路，后来发现要配的环境好多，一开始比较顺利，可是今天竟然花了四个多小时配tesserocr库，其中的坎坷、与艰辛真的是难以启齿，废话不多说了，直接上硬货。
当然啦安装tesserocr库之前，必须要安装tesseracr啦，这里就很简单啦不在仔细讲啦。
在最初的安装时出现了以下的错误：

Exception:

PermissionError: [WinError 32] 另一个程序正在使用此文件，进程无法访问。: 'C:\\Users\\upup\\AppData\\Local\\Temp\\pip-build-fixlbed7\\tesserocr'

解决方法为：修改pip源代码

在"C:\Users\upup\AppData\Local\conda\conda\envs\http\lib\site-packages\pip\compat_init_.py"

的第75行，把return s.decode(‘utf_8’)改为return s.decode(‘cp936’) 即可。在这里不要用记事本修改可以用editplus。处理完毕以上问题之后，又出现了下面的问题（真是让人很生气嗷）

我是通过以下命令安装：

pip3 install tesserocr pillow

但是一直卡着，如下：
在这里插入图片描述就是卡在这个地方，一开始以为是网速的问题，后来又在网上找了好多教程，无济于事。而且报错末尾还出现了：
百度之后，我就安装一个rpy2-2.9.5-cp36-cp36m-win_amd64.whl,文件安装很成功一个命令就解决了。但是呢还是不好使。然后我就继续找教程。发现可以使用以下命令:

pip install tesseract-ocr

很可惜啊，又出错了：

出现这种情况，先不要着急去安装Microdoft Visual C++ 14.0，我们换一种安装方式首先下载对应的.whl文件，一定要与tesseract版本配对：
运行命令：pip3 install tesserocr-2.2.2-cp36-cp36m-win_amd64.whl(这个文件我也是花钱买的。。。。)。
运行这个命令之后，忽然就成功了hhhhhh。如图：

咱也不知道为啥，咱也不敢问。
