Automating Python Pip Dependencies (requirements.txt) for Cloud Telegram Bots

The most frequent reason a Telegram bot works on your local laptop but immediately crashes in the cloud is a missing dependency or incompatible package version.

Best Practices for requirements.txt

Avoid dumping your entire computer's global Python environment into your project. Instead, create an isolated virtual environment:

# Create and activate a fresh virtual environment
python -m venv venv
source venv/bin/activate  # On Windows: venv\Scripts\activate

# Install only what your bot needs
pip install pyrogram tgcrypto aiohttp
pip freeze > requirements.txt

Handling Binary C-Extensions on Linux

Libraries like cryptography, tgcrypto, or pillow compile C-code during installation. On unmanaged VPS servers, you must manually run sudo apt-get install python3-dev build-essential libffi-dev. On BotifyHost, all required native C build toolchains and libraries come pre-installed in the container environment.

Automated Dependency Detection

When you upload your bot project to BotifyHost, our build engine automatically detects your requirements.txt, creates a sandboxed virtual environment, and installs all packages with persistent caching for instant subsequent deploys.
