Dart's pub get command can't find latest versions of some dependencies -


i've noticed on few occasions when setup dependencies in pubspec.yaml pointing latest version, aren't found when run pub get.

for instance, dependency source_gen. latest version of source_gen 0.5.0+1. i'll setup pubspec.yaml file follows:

dependencies:   source_gen: "^0.5.0+1"

then run pub get, , following error:

resolving dependencies... package source_gen has no versions match >=0.5.0+1 <0.6.0 derived from: - servererrors depends on version ^0.5.0+1

i tried several of recent versions, without luck. if following:

dependencies:   source_gen:

and run pub get, source_gen version 0.4.7 installed. i'm not sure understand why. i'm using dart sdk version 1.16.0. second dependency i've had issue , i'm little confused.

edit: requested gunter, full list of dependencies:

dependencies:   http: "^0.11.3+7"   dartson: "^0.2.5"   intl: "^0.12.7+1"   mailer: "^1.0.0"

that's known issue of pub. means pub wasn't able resolve compatible set of dependencies. unfortunately error message misleading. pub prints same error when 1 of dependencies isn't compatible used dart sdk version.

scala - 'wrong top statement declaration' when using slick in IntelliJ -

Image
i'm porting project scala 2.9 2.10, therefore have use slick instead of scalaquery. i'm using slick 2.1.0 since supports ms access. according this tutorial , upgrade guide changed robs object class , added val robs : why error message wrong top statement declaration , how rid of it? edit: i'm new scala... according this question seems can't put val outside of methods or classes, right? code above directly in packge. right approach slick then? should move code in class or trait? according this changed val robs = tablequery[robs] to object robs extends tablequery(new robs(_)) {} . no warnings or errors anymore. :)
