pyserial for Python 2.7.2


I’m new to Python. According to the internets I was looking for the module pyserial after receiving this error:

ImportError: No module named serial

I first tried to install pywin32, it went well. But it seems not to contain pyserial. 🙁

Then I found a single module installer for pyserial, I was not able to install it, it says it did not found the path to python in the registry. 🙁

After that I found this module on, but I don’t know what to do, it does not come with an installer. 🙁

How can I add pyserial to Python (64) 2.7 on Windows 7 64?

You could try it with pip. (Here a question/answer about installing it)

Then type in your shell:

pip install pyserial

The installation of pip on Windows 7 64 is a little tricky:
I added my Python and Python/Scripts path to the PATH env.
Then I opened PythonWin as Administrator, ran from with PythonWin. And then I downloaded pip unpacked it and as Administrator I ran python install on the windows shell and after that pip install pyserial.

Install pySerial as follows:

Download pySerial from – click on pyserial-2.6.tar.gz to download the library.

Run 7-Zip (Start -> All Programs -> 7-Zip -> 7-Zip File Manager).

Open the pyserial-2.6.tar.gz file with 7-Zip (File -> Open).

Double click the “dist” folder.

Single click on the “pyserial-2.6.tar” file and click the “Extract” button at the top of the window. When asked where to put the file, specify c:Python27Libsite-packagespyserial-2.6

Exit from 7-Zip

Now that you have downloaded pySerial, install it:

Open a command window (Start -> All Programs -> Accessories -> Command Prompt) and type into the command line: cd c:Python27Libsite-packagespyserial-2.6

Install pySerial by typing this command (including the path): c:Python27python.exe install

understood that this question is for Windows, but since it comes up first in a Google search let me add an alternative (to pip) for Debian:

sudo apt-get install python-serial

please just go to and download the 64 bit installer and that’s it!

Answered By: argaus

As a slight update there is still the problem that python 64bit for Windows is not compatible with the pyserial installer.

What is not mentioned in other answers but I found very useful to know is that Python 32 bit installs and works fine on Win7 64bit and that means the pyserial installer also works fine.

Obviously if you need 64bit python this is no use to you, but I suspect most of us do not.

pyserial comes now with a precomilied(?) Windows .exe installer:

reviving an old thread but pyserial v3.4 is now available for windows/mac/linux via the conda package manager on the conda-forge channel
(the base conda channel has v2.7)

To install this package with conda run:
conda install -c conda-forge pyserial

pySerial can be installed from PyPI:

python -m pip install pyserial

NOTE : Using the python/python3 executable of the desired version (2.7/3.x).
