树莓派3安装Google Assistant时遇“google-oauthlib-tool: command not found”报错

Hey there, let's work through these problems step by step—no stress, even with rusty coding skills we'll get this sorted out!

First: Fix the google-oauthlib-tool: command not found error #

This usually happens because the tool isn't in your system's executable path, or it got installed to the wrong Python environment. Try these options:

Option 1: Call the tool via Python module (bypasses path issues) #

Instead of running google-oauthlib-tool directly, use Python's module runner to launch it—this avoids path problems entirely. Run this command (replace the path to your client secret file with the actual one):

python3 -m google.oauth2.tools.run_flow --client-secrets /path/to/your/client_secret.json --scope https://www.googleapis.com/auth/assistant-sdk-prototype --save --headless

Option 2: Reinstall the dependency to the correct Python 3 environment #

It's possible the tool was installed to Python 2 instead of 3. Reinstall it explicitly for Python 3 with:

sudo pip3 install google-auth-oauthlib[tool]

After this, try running google-oauthlib-tool again, or stick with the Python module method above if that's easier.

Next: Fix the original No module named googlesamples.assistant.auth_helpers error #

This module is part of the Google Assistant SDK's sample helper package. You just need to install the full SDK with sample dependencies. Run this:

sudo pip3 install google-assistant-sdk[samples]

Once this finishes, your original authentication script should be able to find that missing module.

How to check your Google Assistant SDK version #

No problem—checking the version is straightforward. Run this in the terminal:

pip3 show google-assistant-sdk

Look for the Version line in the output—that's your installed SDK version.

Quick Raspberry Pi-specific tip #

Since Raspbian often has both Python 2 and 3 installed, always use pip3 and python3 (not pip/python) to make sure packages go to the right environment. If you run into permission issues, try installing without sudo using the --user flag:

pip3 install --user google-assistant-sdk[samples] google-auth-oauthlib[tool]

If you do this, the google-oauthlib-tool will be in ~/.local/bin—you can either run it directly with that full path, or add ~/.local/bin to your system's PATH variable for easier access.
