无法运行Unity8opencliPart作用域示例

Question

按照这页面的说明，我安装了Ubuntu并下载了教程源代码。

Opencli部件作用域构建正确，但我有一个运行时错误：

$ unity-scope-tool src/openclipart-scope.ini 
scoperegistry: no remote registry configured, only local scopes will be available
RegistryObject::ScopeProcess::exec(): Process for scope: "openclipart-scope" started
file:///usr/share/unity8/Dash/DashContent.qml:100: TypeError: Cannot read property 'loaded' of null

file:///usr/share/unity8/ScopeTool.qml:149:23: Unable to assign null to QString

file:///usr/share/unity8/Dash/DashContent.qml:100: TypeError: Cannot read property 'loaded' of null

有什么建议吗？

由于Unity8(以及扩展的unity-scope-tool )的设计使得它们可以在Mir和X11下运行，因此依赖关系中存在一些模糊性。您得到的错误表明它正在尝试使用Mir后端。

您应该能够通过安装unity8-fake-env包来解决这个问题，它提供了在X下运行该工具所需的一些API：

sudo apt-get install unity8-fake-env
