Common Issues
Build Failed When Installing Dependencies
Section titled “Build Failed When Installing Dependencies”If the deployment workflow correctly finds your dependency file (e.g. pyproject.toml) but you encounter “Build Failed” errors because some dependencies cannot be built from source, this typically means a package doesn’t have the necessary pre-built wheels for the Python version you are using.
Solution: Pin your Python version to one that has pre-built wheels available for all your dependencies. See the Older Python for Older Packages section for more details on how to do this.
