python - No module named serial

and I got a question when I run my Python code.

I installed Python 2.7 on Windows 7, bit 64. I got an error "No module named serial" when I compiled my code:

import serial

ser = serial.Serial("COM5", 9600)

ser.write("Hello world")

x = ser.readline()

print(x)

I tried many ways to crack this problem, such as installed Canopy to setup virtual environment, make sure 'pip' is there, no Python v 3.x installed. But still cannot get it out.

Any advice would be appreciated.

Serial is not included with Python. It is a package that you'll need to install separately.

Since you have pip installed you can install serial from the command line with:

pip install pyserial

Or, you can use a Windows installer from here. It looks like you're using Python 3 so click the installer for Python 3.

Then you should be able to import serial as you tried before.
