尝试Qt5.12在travis-cilinux 上安装时看到以下错误。有人请帮忙
$ ./qt-opensource-linux-x64-5.12.10.run
QFactoryLoader::QFactoryLoader() ignoring "org.qt-project.Qt.QPA.QPlatformIntegrationFactoryInterface.5.3" since plugins are disabled in static builds
qt.qpa.xcb: could not connect to display
qt.qpa.plugin: Could not load the Qt platform plugin "xcb" in "" even though it was found.
This application failed to start because no Qt platform plugin could be initialized. Reinstalling the application may fix this problem.
Available platform plugins are: minimal, xcb.
