Issue

pelican command send Error:

pkg_resources.DistributionNotFound: The **'pygments<2.7.0,>=2.6.1'** distribution was not found and is required by pelican

My installed version is effectively pygments==2.7.2; I think that a dependency on a specific (old) version of a package is a bug.

Thanks!

No, it's not a bug to have limitations on the versions of a dependency. Using virtual environments is recommended to avoid clashes between dependencies for different applications, precisely for this reason.

OK, thank you!

@avaris is right. Pygments is pinned to a specific version because otherwise it causes things to break unexpectedly. Case in point: tests currently fail on Pygments v2.7.2. Pull requests to address that would be welcome! 😁
