dart - 在新的Dart项目中未看到的Dart模板

Question

由于推荐，我试图将Webstorm用于我的Dart项目。我已经安装了它，并将其指向Dart sdk和dartium路径。在创建新的Dart项目时，我只会看到Dart Web应用程序和Dart命令行应用程序。没有聚合物模板或任何其他模板。我该怎么做才能看到那些模板。
Dart 发售的相关版本:
Dart 1.11.0(ref 65704b3)DEV(SDK)
Dart 1.11.0(ref 65704b3)(稳定)DARTIUM

我删除并尝试重新安装stagehand，但出现以下错误

多次尝试只会导致相同的错误。
我做了一个酒吧缓存修复，但是结果是一样的。

Stagehand提供以下模板；聚合物不是其中之一。

$ stagehand
Stagehand will generate the given application type into the current directory.

usage: stagehand <generator-name>
    --[no-]analytics    Opt out of anonymous usage and crash reporting.
-h, --help              Help!
    --version           Display the version for stagehand.
    --author            The author name to use for file headers.
                        (defaults to "<your name>")

Available generators:
  console-full   - A command-line application sample.
  package-simple - A starting point for Dart libraries or applications.
  server-shelf   - A web server built using the shelf package.
  web-angular    - A web app with material design components.
  web-simple     - A web app that uses only core Dart libraries.
  web-stagexl    - A starting point for 2D animation and games.
