🐍 Python Installation & Package Management (Windows)

This guide explains how to install Python correctly for all users on Windows and how to install packages online and offline using the python_pck repository.

---

1️⃣ Install Python (For All Users)

Download Python

Download Python from the official website:

https://www.python.org/downloads/windows/

Installation options (IMPORTANT)

During installation:

• ✅ Install for all users
• ✅ Add Python to PATH
• ❌ Do NOT install via Microsoft Store

This installs Python under:

C:\Program Files\Python311\

---

2️⃣ Verify Python Installation

Open Command Prompt and run:

where python

Expected output

C:\Program Files\Python311\python.exe

Check version:

python --version

Example:

Python 3.11.0

---

3️⃣ Understand Where Python Installs Packages

Python installs packages in different locations depending on how it is run.

System-wide installation path (CORRECT)

C:\Program Files\Python311\Lib\site-packages

User installation path

C:\Users\<username>\AppData\Roaming\Python\Python311\site-packages

To make packages available to all users, they must be installed in the system-wide path.

---

4️⃣ Install Packages ONLINE (Internet Access)

Open Command Prompt as Administrator

Always run package installs as Administrator.

Install a package

"C:\Program Files\Python311\python.exe" -m pip install requests

Install multiple packages

"C:\Program Files\Python311\python.exe" -m pip install requests pandas openpyxl numpy

---

5️⃣ Verify Online Installation

"C:\Program Files\Python311\python.exe" -c "import requests, pandas, openpyxl, numpy; print('ALL OK')"

Check install location:

"C:\Program Files\Python311\python.exe" -c "import pandas; print(pandas.__file__)"

Expected:

C:\Program Files\Python311\Lib\site-packages\pandas\__init__.py

---

6️⃣ Install Packages OFFLINE (Using python_pck Repo)

Clone or copy the repository

git clone https://github.com/shivamzoos/python_pck

Or copy the repository folder manually to the target machine.

7️⃣ Clean Old Package Installations (Recommended)

Before offline installation, remove any existing packages:

"C:\Program Files\Python311\python.exe" -m pip uninstall -y ^
requests pandas openpyxl numpy ^
pytz python-dateutil et-xmlfile urllib3 ^
charset-normalizer idna certifi six tzdata

Optionally remove leftover user packages:

rmdir /s /q "C:\Users\<username>\AppData\Roaming\Python\Python311"

---

8️⃣ Install Packages OFFLINE (System-Wide)

Navigate to the offline package directory:

cd python_pck\offline_packages

Run Command Prompt as Administrator and execute:

"C:\Program Files\Python311\python.exe" -m pip install ^
 --no-index ^
 --find-links=. ^
 --ignore-installed ^
 -r requirements.txt

What these flags do

Flag	Description
--no-index	Prevents internet usage
--find-links=.	Uses local wheel files
--ignore-installed	Forces clean installation

---

9️⃣ Verify Offline Installation

"C:\Program Files\Python311\python.exe" -c "import requests, pandas, openpyxl, numpy; print('ALL OK')"

Verify dependencies:

"C:\Program Files\Python311\python.exe" -c "import pytz, dateutil, et_xmlfile, urllib3; print('DEPS OK')"

---

🔍 Check Installed Package Paths

"C:\Program Files\Python311\python.exe" -c "import site; print(site.getsitepackages())"

Expected output:

['C:\\Program Files\\Python311',
 'C:\\Program Files\\Python311\\Lib\\site-packages']

---

🚫 Common Mistakes to Avoid

• ❌ Installing Python via Microsoft Store
• ❌ Running pip install without Administrator privileges
• ❌ Using pip install --user
• ❌ Mixing multiple Python installations
• ❌ Installing packages without verifying paths

---

🧠 Key Takeaway

Install Python for all users and install packages as Administrator. This ensures packages are available system-wide and usable by everyone.

---

✅ Status

Python installed correctly
Packages installed system-wide
Online and offline installs supported
