Windows: google-colab-cli v0.6.0 crashes on startup due to unconditional termios import

[spinx66]

Environment

• OS: Windows 10 (also likely affects Windows 11)
• Python: 3.12
• google-colab-cli: 0.6.0
• Installed using: uv tool install google-colab-cli

Description

The CLI installs successfully, but every command immediately crashes before execution.

Example:

colab --help

Traceback ends with:

ModuleNotFoundError: No module named 'termios'

The import chain is:

colab_cli.cli
-> colab_cli.commands.execution
-> colab_cli.console
-> import termios

colab_cli/console.py imports the Unix-only modules termios and tty at module import time.

Because execution.py imports connect_console eagerly, the CLI crashes on startup on Windows, even for commands that do not require an interactive terminal (such as upload, download, or run).

Expected behavior

Commands that do not require a TTY should work on Windows.

The console implementation could either:

• lazily import connect_console only when needed, or
• conditionally import the POSIX-specific modules.

Reproduction

1. Install google-colab-cli v0.6.0
2. Run:

colab --help

3. Observe:

ModuleNotFoundError: No module named 'termios'
