If you're getting those errors when running yarn directly, that implies
there's something wrong with your yarn installation. What is the full

If you're using QT 5.0+, then it'll default to QtWebEngine, which I guess
you don't have installed. QtWebKit is generally preferred for performance

qmake "DEFINES += PGADMIN4_USE_WEBKIT"
