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 python.org, 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
Solution:
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 ez_setup.py from http://pypi.python.org/pypi/setuptools#downloads with PythonWin. And then I downloaded pip unpacked it and as Administrator I ran python setup.py install on the windows shell and after that pip install pyserial.
From http://www.instructables.com/id/The-Arduino-Internet-Gizmo/step19/Installing-the-software/
Install pySerial as follows:
Download pySerial from http://pypi.python.org/pypi/pyserial - 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:\Python27\Lib\site-packages\pyserial-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:\Python27\Lib\site-packages\pyserial-2.6
Install pySerial by typing this command (including the path): c:\Python27\python.exe setup.py 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
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.
please just go to http://www.lfd.uci.edu/~gohlke/pythonlibs/#pyserial and download the 64 bit installer and that's it!
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 comes now with a precomilied(?) Windows .exe installer: https://pypi.python.org/pypi/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).
I find the 2.7 installation files here
https://pypi.org/project/pyserial/2.7/#files

I've coded a game in Pygame using Pycharm, and I want to make it into a downloadable desktop application so that other people can download and use it even if they do not have python or the necessary files. The problem is I don't know how to. I've heard of py2exe and py2app before. I tried py2exe but then realized that .exe was for windows, and I was using a Mac. I read the py2app documentation, but it was very confusing and hard to understand, and none of the things they said worked. They said to use the pip command to install py2app inside the terminal, but I tried it and it said that it did not recognize the pip command. Can someone please help? Thanks!
Sorry if this question is long. I am trying to tell as much information as possible.
You can use pyinstaller if you package the application in Mac OS it will run on Mac.
Click here for instruction on how to install the package and use it.
Which installation of Python do you use? I had bad experience with Homebrew when it came to packaging, then I've removed it and switched to Python3.9 downloaded directly from python.org and everything works well now.
Depending on your Python installation, it is possible that you don't have pip installed on your computer. Via terminal, you can check it using
python -m pip --version
and you should get a response of this type:
pip X.Y.Z from .../site-packages/pip (python X.Y)
If you don't have pip, you can either re-install Python as mentioned above, or you can just install pip using these instructions.
As soon as you have pip installed, you can install py2app using
pip install py2app
I'm a little lost on how to get pyodbc installed in my computer.
I have python 3.6.1
The link
http://support.esri.com/en/technical-article/000011656
pointed me to another link
https://github.com/mkleehammer/pyodbc
Which is vague.
I'm used to downloading and running an exe for install.
This link is unclear and says all I have to do is:
"pip install pyodbc"
What exactly do I need to do to get this working?
Since you have not mentioned which OS you are using,
I will assume that you are on windows (as you have mentioned that you are used to install using .exe).
Firstly you need to know what a pip is:
pip is basically a package manager for python packages used to install 3 rd party packages which do not bundle along with the python distribution.
On linux pip comes pre installed also if you are using python version 3.4 onwards or python 2.7.9 you will be having pip pre installed on your system.
All you have to do it to open the command prompt issue the command
pip install package-name(pyobdc here)
it will do the job.
If you do not find pip in your distribution you can refer this link
How do I install pip on Windows?
open cmd in your computer and type
pip install pyobdc
Hello there and welcome to python programming. Basically python comes with its package installer so either you can go to any interpreter that you are using and type pip install pyobdc or use the command prompt in windows and type in pip install pyobdc. This would install your module and just remember to put import pyobdc at the top of the code if you want to use this package. Further information can be found on here
I have experiencing a problem when installing pywin32 for python 3.5 to my windows 7 PC. The problem is, installation wizard stating that I have no any python versioned as 3.5 in my registery.
My pywin32 file is downloaded from here => pywin32-220.win-amd64-py3.5.exe.
The thing is, when I run python -V code line, I am able to see that I've python 3.5.2 on my PC.
So I don't understand that is the real problem is. Did I get something wrong in logical way?
Any help will be greatly appreciated.
I strongly suggest you delete everything about python on your computer (do not forget to delete related PATH variables) and install Anaconda. You will be able to create several environments and much more.
You can find it in the link below;
https://www.continuum.io/downloads
Export in regedit HKLM\SOFTWARE\Python\PythonCore\3.5-32 and subkeys Replace in an editor "3.5-32" by "3.5" Import the resulting registry file again (by doubleclicking on it).
use "py -m pip install pypiwin32" instead of "py -m pip install pywin32"/"pip install pywin32".
However, I found that pypiwin32 installs version 219. Pywin32's lates version is 221.
I have Python 2.7.11 installed on my machine which to my understanding should come with pip, however when I check the C:\Python27\Tools\Scripts\ directory there is no pip.exe present.
I have tried completely removing and reinstalling Python 2.7.11 without success. Running the installer pip is set to be installed, but after the install pip is nowhere to be found.
I also have Python 3.4 installed which has pip as expected. Any thoughts?
I encountered the same problem - pip not installed - with python-2.7.16, Win10, installing for 'all users'. It was resolved when I allowed the MSI installer to target the default location (C:\Python27) rather than changing it to under Program Files (x86). I've no clue why this changed anything.
python2.7.11 should install pip into c:\python27\scripts, you can take a look here
I used https://pip.pypa.io/en/stable/installing/ to make it install. Odd that an outside body has to make a tool to get pip to install. There is no mention of pip.pypa.io on the Python web site.
Although I got error messages, it did install, so check carefully.
You also may see a message suggesting that you upgrade to pip 9.0 with the command 'pip install --upgrade.' I highly recommend that.
Also, make sure you are in the directory where pip.exe is located when you run the commands. They don't tell you that, because they assume you know that, but we're not all geeks.
For people who are running into this issue, I have a Windows 10 x86 dev box that I use for exploit development, Python 2.7 was installed due to Immunity Debugger, this install did not include the new SSL package and did not include "pip".
There was no "C:\Python27\Scripts" folder which included pip. I did have a "C:\Python27\Tools\Scripts" folder which did not have pip installed.
I tired to install pip as suggested but did not work. Best way is to uninstall Python and install newest version, currently mine is 2.7.15 which came with pip as an option. This is what solved my issue, any older version of Python will need upgraded to support the SSL packages. You will receive the same errors when you try to install pip on an older version.
If you have reinstalled Python which included the SSL package and it still does not have pip, trying installing pip this way:
1. curl https://bootstrap.pypa.io/get-pip.py -o get-pip.py
2. python get-pip.py
https://pip.pypa.io/en/stable/installing/
This should work if you have a newer version of Python.
Once you have installed pip or newer version of python, go to "C:\Python27\Scripts" and you should see pip.exe.
I have installed "python-2.7.16" in my windows 10 PC. PIP is installed under "C:\Python27\Scripts". One can add the "C:\Python27\Scripts" path to environment variable and then access pip command from command prompt.
To add the path in environment variable:
Control Panel\System and Security\System --> Advanced System Settings --> Advanced --> enviroment variables --> under system variable --> Path(variable name)
Had the issue where no matter which version of python 2.7 I installed on windows 10 there was no pip.exe generated in the "Scripts" folder.
I solved it by ensuring that that MSI Installer file had Admin privileges before installing
if pip is not installed you can use easy_install.exe to install pip and other modules
you can find easy install in
python -m easy_install pip
I had the same issue:
Installed Python 27
Tried to use pip, but failed with unrecognized command error
Checked installation: no "C:\Python27\Scripts", only "C:\Python27\Tools\Scripts"
This issue happens only on some versions of Windows.
HOW TO FIX IT:
Uninstall Python 27
Reinstall Python 27, but unselect "pip" feature
Check installation: no "C:\Python27\Scripts" as expected
Start the installer again and use "Change Python"
Set "pip" and "Add Python.exe to Path" features to be installed
Check installation: "C:\Python27\Scripts" is now correctly present
So for some unknown reason, pip is not correctly installed on some versions of Windows if it is installed during default Python 27 setup. To fix this issue, pip must be installed afterwards using the "Change Python" setup.
I meet the same issue when install Python 2.7.9. The installer does not come with pip.
Solution:
Install newer python2 x86 version: https://www.python.org/downloads/release/python-2718/
Then pip is located at C:\Python27\Scripts\pip.exe
It happens on windows as you should have admin rights to install anything on disk C.
I have the same issue Scripts folder was not installed. I would sugest to instal it on disk D.
I'm using Python 3.4 on Windows. When I run a script, it complains
ImportError: No Module named 'PyQt4'
So I tried to install it, but pip install PyQt4 gives
Could not find any downloads that satisfy the requirement PyQt4
although it does show up when I run pip search PyQt4. I tried to pip install python-qt, which installed successfully but that didn't solve the problem.
What am I doing wrong?
Here are Windows wheel packages built by Chris Golke - Python Windows Binary packages - PyQt
In the filenames cp27 means C-python version 2.7, cp35 means python 3.5, etc.
Since Qt is a more complicated system with a compiled C++ codebase underlying the python interface it provides you, it can be more complex to build than just a pure python code package, which means it can be hard to install it from source.
Make sure you grab the correct Windows wheel file (python version, 32/64 bit), and then use pip to install it - e.g:
C:\path\where\wheel\is\> pip install PyQt4-4.11.4-cp35-none-win_amd64.whl
Should properly install if you are running an x64 build of Python 3.5.
QT no longer supports PyQt4, but you can install PyQt5 with pip:
pip install PyQt5
You can't use pip. You have to download from the Riverbank website and run the installer for your version of python. If there is no install for your version, you will have to install Python for one of the available installers, or build from source (which is rather involved). Other answers and comments have the links.
If you install PyQt4 on Windows, files wind up here by default:
C:\Python27\Lib\site-packages\PyQt4*.*
but it also leaves a file here:
C:\Python27\Lib\site-packages\sip.pyd
If you copy the both the sip.pyd and PyQt4 folder into your virtualenv things will work fine.
For example:
mkdir c:\code
cd c:\code
virtualenv BACKUP
cd c:\code\BACKUP\scripts
activate
Then with windows explorer copy from C:\Python27\Lib\site-packages the file (sip.pyd) and folder (PyQt4) mentioned above to C:\code\BACKUP\Lib\site-packages\
Then back at CLI:
cd ..
(c:\code\BACKUP)
python backup.py
The problem with trying to launch a script which calls PyQt4 from within virtualenv is that the virtualenv does not have PyQt4 installed and it doesn't know how to reference the default installation described above. But follow these steps to copy PyQt4 into your virtualenv and things should work great.
Earlier PyQt .exe installers were available directly from the website download page. Now with the release of PyQt4.12 , installers have been deprecated. You can make the libraries work somehow by compiling them but that would mean going to great lengths of trouble.
Otherwise you can use the previous distributions to solve your purpose. The .exe windows installers can be downloaded from :
https://sourceforge.net/projects/pyqt/files/PyQt4/PyQt-4.11.4/
It looks like you may have to do a bit of manual installation for PyQt4.

With current latest python 3.6.5
pip3 install PyQt5
works fine
For Windows:
download the appropriate version of the PyQt4 from here:
https://www.lfd.uci.edu/~gohlke/pythonlibs/#pyqt4
and install it using pip (example for Python3.6 - 64bit)
pip install PyQt4‑4.11.4‑cp36‑cp36m‑win_amd64.whl
Try this for PyQt5:
pip install PyQt5
Use the operating system on this link for PyQt4.
Or download the supported wheel for your platform on this link.
Else use this link for the windows executable installer.
Hopefully this helps you to install either PyQt4 or PyQt5.
install PyQt5 for Windows 10 and python 3.5+.
pip install PyQt5
If you have error while installing PyQt4.
Error: PyQt4-4.11.4-cp27-cp27m-win_amd64.whl is not a supported wheel on this
platform.
My system type is 64 bit, But to solve this error I have installed PyQt4 of 32 bit windows system, i.e PyQt4-4.11.4-cp27-cp27m-win32.whl - click here to see more versions.
Kindly select appropriate version of PyQt4 according to your installed python version.
You can also use this command to install PyQt5.
pip3 install PyQt5
I am using PyCharm, and was able to install PyQt5.
PyQt4, as well as PyQt4Enhanced and windows_whl both failed to install, I'm guessing that's because Qt4 is no longer supported.
Try using python 3.6,
then install sip
pip install sip
then follow the steps mentioned by #Jay https://stackoverflow.com/a/48078369/8352081
