问题
I cannot add the package mdl https://pub.dartlang.org/packages/mdl to pub cache using either the
command pub cache add mdl
or using the dependency
dependencies:
mdl: "^1.1.2"
in my pubspec.yaml file.
The author says it is a Windows issue as it works as designed on Linux and iOS.
I am using the current WebStorm on Windows 8.1 x64. This is the first time I am having such an issue.
Using the command line
pub --trace cache add mdl
I receive the following trace
J:\workspace\epimss\dart\epimss_app>pub --trace cache add mdl
Downloading mdl 1.1.2...
Timed out after 30.0s while downloading https://pub.dartlang.org/packages/mdl/versions/1.1.2.tar.gz.
This is likely a transient error. Please try again later.
