own local mirror, for example. Package mirror URLs are constructed by joining

this variable with the SHA2 checksum of the package file.
|

If the mirror being used does not have the same checksum (*e.g.* with a

pull-through cache like Artifactory), you can set the

`PYTHON_BUILD_MIRROR_URL_SKIP_CHECKSUM` environment variable.

If you don't have an SHA2 program installed, python-build will skip the download

mirror and use official URLs instead. You can force python-build to bypass the

mirror by setting the `PYTHON_BUILD_SKIP_MIRROR` environment variable.
