ImportError: No module named serial in windows 7 python 2.7 and python 3.3

I am trying to install python serial driver. I have done some steps as follows:

I installed the pyserial-2.7.win32.exe on my pc;

I wrote this python file.

#coding=gb18030

import serial
import time
import random
class EMCTest: 
   def __init__(self, Port="COM25"): # Port =3: COM4(According To You PC Environment, It Needs to Be Changed Before Testing.)
       self.l_serial = None
       self.port = Port

When I run *.py file in python 2.7 I get the following output

Traceback (most recent call last):

File "C:\Users\davwang\Desktop\X100.py", line 4, in <module>
import serial
ImportError: No module named serial

A few things could be wrong. Is your Python x86 or x64? Did the installer actually install (look in site-packages).

Instead of doing complicated work finding what's wrong with your install, try installing with pip the easiest way to install libraries. Use pip install pyserial. This is widely considered the best way to install Python libraries. It automatically deals with dependencies, operating system and x86 versus x64.

EDIT: It looks to me that the python folder isn't in your system path. You can sys.path.append("/path/to/python/"), or you can run set PYTHONPATH=%PYTHONPATH%;<Path/to/python> in cmd.

I had a similar problem with nearly all imported modules. I couldn’t figure it out, because using pip install was what i have done all the time. I solches with a very nasty and unelegant way

import sys
sys.path.insert(0, u'/…/…/…/python2.7/site-packages')

I believe that there is another way, but i haven’t found one in weeks and this actually worked for me.
