build - Dart:执行 “pub get”和 “pub build”时出错

Question

我们通过运行脚本来实现DART自动化，该脚本导航到项目文件夹(.yaml文件所在的位置)并运行“pub get”和“pub build”。它工作了一段时间，但现在(两种情况下)我们都得到了:

Unhandled exception:
Illegal argument(s): join(null, "Pub", "Cache"): part 0 was null, but part 1 was not.
#0      _validateArgList (package:path/src/context.dart:497)
#1      Context.join (package:path/src/context.dart:187)
#2      join (package:path/path.dart:235)
#3      main (file:///e:/b/build/slave/dart-editor-win-stable/build/dart/sdk/lib/_internal/pub/bin/pub.dart:69)
#4      _startIsolate.isolateStartHandler (dart:isolate-patch/isolate_patch.dart:214)
#5      _RawReceivePortImpl._handleMessage (dart:isolate-patch/isolate_patch.dart:124)

这可能是什么原因？我们使用SDK 1.4.0。

谢谢，

您应该在AppData\Roaming上具有环境变量“APPDATA”

并将PUB_CACHE设置到您要保存酒吧发布的文件夹
