Managing dependencies

Cloud Functions can automatically install dependencies necessary for a function to run. To do this, when creating a new function version, it executes the pip install command in the project root (folder with the function).

To specify the necessary function libraries, list them in the requirements.txt file. For more information about the requirements.txt file format, see the pip documentation.

Sample requirements.txt file:

```
boto3==1.13.15
attrs=19.3.0
```

The dependency installation process has some restrictions. For more information, see Quotas and limits. You can view the dependency installation log using the link that appears in the list of operations.
