I cannot install the pywin32 package on Domino using pip install

Issue:

A user wants to install package 'pywin32' via pip install and it fails with error: 

ERROR: Could not find a version that satisfies the requirement pywin32 (from versions: none) 
ERROR: No matching distribution found for pywin32 
Note: you may need to restart the kernel to use updated packages.

Why does this occur:

The short answer, because it relies on the Windows operating system's architecture, libraries, and APIs, which are fundamentally different from those in Linux, pywin32 does not run on Linux-based workspaces like those at Domino Data Lab, the long answer:

1. pywin32 offers python bindings for only the Windows API, allowing python programmes to interface with many Windows-specific features such as system calls, GUI manipulation, registry operations, and more. The Windows API is only available on Windows and is not available on Linux.
2. The package is dependent on system-level interaction with the Windows operating system. It makes use of Windows-specific components and services such as COM (Component Object Model) objects, Active Directory services, Windows Management Instrumentation (WMI), and others. These components do not exist or are not compatible with Linux. 
3. pywin32 is designed for and optimised for the Windows operating system. It makes use of Windows-specific programming methods, data structures, and libraries that may or may not be compatible with or have counterparts in linux.
4. The package relies on Windows-specific DLLs (Dynamic Link Libraries) and system resources that are not accessible on Linux. These dependencies ensure that pywin32 can only run on a Windows platform.

As a result, using pywin32 on Linux will almost certainly result in import problems, missed function calls, and other compatibility difficulties. To accomplish comparable functionality on Linux, you'd need to find other libraries or frameworks that are especially intended for Linux and offer comparable features and capabilities.

Resolution:

Ultimately you would have to look to your applications team for support, however there are some Python libraries that can provide similar functionality on Linux as pywin32 does on Windows:

1. The python-xlib package allows you to interface with the Linux X Window System. It includes features for interacting with windows, events, input devices, and more. You may use python-xlib to automate GUI interactions, get window information, and conduct window management operations.
2. Python's standard library subprocess module allows you to run external commands and interact with the command-line environment. It allows you to run Linux-specific command-line tools and utilities from within your Python script, giving you access to the vast possibilities of the Linux command-line environment.
3. psutil is a cross-platform library that offers an interface for retrieving and monitoring system information and resources such as CPU, memory, disk use, and network data. It enables you to acquire system measurements, manage processes, and conduct system-related tasks programmatically.
4. The python database api (DB-API) provides a standardised interface for Python to connect with databases. For Linux, there are various database-specific Python libraries available, including psycopg2 for PostgreSQL, mysql-connector-python for MySQL, and cx_Oracle for Oracle Database.
