[QtTester]

Hi guys.
I found this:
https://bugreports.qt.io/browse/QTBUG-77387
and this:
https://forum.qt.io/topic/136650/python2-error-during-webengine-build-qt-5-12-5
But i can still not build the module, in config.log it said:

Found flex from path: D:/qt-everywhere-src-5.15.9/gnuwin32/bin/flex.exe
test config.qtwebengine_buildtools.tests.webengine-flex succeeded
executing config test webengine-python2
test config.qtwebengine_buildtools.tests.webengine-python2 gave result C:/Python27/python2.exe
executing config test webengine-nodejs
'nodejs.exe' not found in PATH. Checking for 'node.exe'.
'node.exe' not found in PATH. Giving up.

but python or python2 is fine:
