func (*Supplier) InstallCommonBuildDependencies ¶ added in v1.8.26

func (s *Supplier) InstallCommonBuildDependencies() error

sdist packages have 2 kinds of dependencies: build-time deps and runtime-deps. Before PEP-517, there was no standard to specify a package's build-time deps, but with PEP-517, a package defines its build-time deps in its pyproject.toml. In an online install, pip reads it and downloads build-time deps and builds the sdist. In a vendored (offline) install, this is not possible because "pip download" is not smart enough to download build-time deps during vendoring (pypa/pip issue#8302). Before pip 23.1, when build-time deps were missing, pip fell back to using the legacy 'setup.py install' method. pip 23.1 started enforcing PEP 517. Therefore, for vendored apps with sdists, we install the 2 most common build-time dependencies - wheel and setuptools. These are packaged by the dependency pipeline within the "pip" dependency.
