Pub build throws the following error
Resolving dependencies... Error on line 1, column 1 of https://pub.dartlang.org/api/packages/source_maps/versions/0.10.0%2B2: Invalid version constraint: Could not parse version
It seems pub tries to update https://pub.dartlang.org/packages/source_maps version to 0.10.0+2. The url contains version number and its encoded from + sign to %2B.
pub version 1.6.0,
OS Fedora 19, Any ways to overcome this?
Pub version 1.6.0 didn’t yet support the
+ in version constraints.
You need to update to a newer version.
