Install python reptile --- tesserocr library

Summer vacation the next day, opened the way of reptiles, later found to be much better with the environment, a relatively smooth start, but even today, it took more than four hours with tesserocr library, one of the frustrations, hardships and really hard to say, ado, directly on the hard goods.
Before installing tesserocr library of course, you must be installed tesseracr you, here it is a simple matter careful not to speak it.
The following error occurred during the initial installation:

Solution to: modify the source code pip

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

The first line 75, the return s.decode ( 'utf_8') to return s.decode ( 'cp936') can. Here you do not use Notepad can be used to modify editplus. After the deal is completed the above problems, there was the following questions (really make people very angry wailing)

I was following command to install:

pip3 install tesserocr pillow

But it has been stuck with, as follows:
that is stuck in this place, at first thought it was speed, and later the Internet to find a lot of tutorials, to no avail. And there was also the end of an error:
After Baidu, I installed a rpy2-2.9.5-cp36-cp36m-win_amd64.whl, file installation is successful a command will be solved. But it was so bad. Then I will continue to look for tutorials. It can be found using the following command:

pip install tesseract-ocr

Unfortunately, ah, but also wrong:

this happens, do not worry to install Microdoft Visual C ++ 14.0, we put it another way First, download the installation file corresponding .whl, must be paired with the tesseract version:
run the command: pip3 install tesserocr -2.2.2-cp36-cp36m-win_amd64.whl (this file I also spend money ....).
After running this command, suddenly successful hhhhhh. Figure:

I do not know why, we do not dare to ask.
