原因

因?yàn)樾枰趙indows上調(diào)試板子的串口，用到了python的serial方法。

在pycharm中雖然安裝了pip和serial，但是執(zhí)行py的時候一直在報錯，提示

            
              AttributeError: module 'serial' has no attribute 'Serial'
            
          

于是準(zhǔn)備直接安裝windows下的serial。

安裝

?

環(huán)境前提：Python2.7已經(jīng)安裝完畢

?

1.下載ez_setup-0.9，地址

https://pypi.python.org/packages/ba/2c/743df41bd6b3298706dfe91b0c7ecdc47f2dc1a3104abeb6e9aa4a45fa5d/ez_setup-0.9.tar.gz

2.解壓后，運(yùn)行ez_setup.py

3.在python的安裝目錄下的S會生成一個Scripts文件夾，使用管理員權(quán)限打開cmd或者powerShell，然后執(zhí)行?.\easy_install.exe pip

4.查看pip版本，證明安裝成功?
?

            
              .\pip.exe --version

pip 19.1.1 from C:\Program Files (x86)\Python\2.7\lib\site-packages\pip (python 2.7)
            
          

5.安裝pyserial

            
              .\pip.exe install pyserial


DEPRECATION: Python 2.7 will reach the end of its life on January 1st, 2020. Please upgrade your Python as Python 2.7 won't be maintained after that date. A future version of pip will drop support for Python 2.7.

6.完畢

此時再次打開pycharm，運(yùn)行py程序，發(fā)現(xiàn)成功執(zhí)行，可以通過serial正常調(diào)用串口
