Installed pywin 32 -- still getting error -- "No module named win32com.client."

Discussion Category: Python

Additional Information: I'm trying to install pywin32 (32 bit 2.7) so that I can run python from ArcGIS 10.2.1 (32 bit), and have access to the pywin modules. But I am getting the error "No module named win32com.client." I have installed the pywin32 package using pip, but I still get this error when I try to import the win32com.client module in my Python script.

Understanding the Issue

The error "No module named win32com.client" typically occurs when the Python interpreter is unable to find the win32com.client module in the installed packages. This can happen even after installing the pywin32 package using pip. There are several reasons why this might happen, including:

Incorrect Installation: The pywin32 package might not have been installed correctly, or the installation might have failed.
Multiple Python Versions: If you have multiple versions of Python installed on your system, the pywin32 package might have been installed for a different version of Python.
Package Conflicts: There might be conflicts between different packages that are installed on your system, which can prevent the win32com.client module from being loaded.

Troubleshooting Steps

To troubleshoot this issue, you can try the following steps:

Step 1: Check the Installation

First, let's check if the pywin32 package has been installed correctly. You can do this by running the following command in your terminal or command prompt:

pip show pywin32

This will display information about the pywin32 package, including its version and installation location.

Step 2: Check the Python Version

Next, let's check which version of Python is being used by the ArcGIS 10.2.1 application. You can do this by running the following command in your terminal or command prompt:

python -c "import sys; print(sys.version)"

This will display the version of Python that is being used.

Step 3: Check the win32com.client Module

Now, let's check if the win32com.client module is available in the installed packages. You can do this by running the following command in your terminal or command prompt:

python -c "import win32com.client; print(win32com.client.__file__)"

This will display the location of the win32com.client module.

Step 4: Reinstall the pywin32 Package

If the above steps do not resolve the issue, you can try reinstalling the pywin32 package using pip. You can do this by running the following command in your terminal or command prompt:

pip uninstall pywin32
pip install pywin32

This will uninstall the pywin32 package and then reinstall it.

Step 5: Check for Package Conflicts

Finally, let's check for any package conflicts that might be preventing the win32com.client module from being loaded. You can do this by running the following command in your terminal or command prompt:

pip freeze

This will display a list of all the packages that are installed on your system.

Conclusion

In conclusion, the error "No module named win32com.client" can occur due to a variety of reasons, including incorrect installation, multiple Python versions, and package conflicts. By following the troubleshooting steps outlined above, you should be able to resolve this issue and get access to the pywin modules in your Python script.
