ubuntu上源码编译qt时报错 Project ERROR: Building QtQml requires Python.

make[1]: Leaving directory '/home/qt/qt-everywhere-src-5.12.8/qtsvg'
cd qtdeclarative/ && ( test -e Makefile || /home/qt/qt-everywhere-src-5.12.8/qtbase/bin/qmake -o Makefile /home/qt/qt-everywhere-src-5.12.8/qtdeclarative/qtdeclarative.pro ) && make -f Makefile install
sh: 1: python: not found
Project ERROR: Building QtQml requires Python.
Makefile:348: recipe for target 'module-qtdeclarative-install_subtargets' failed
make: *** [module-qtdeclarative-install_subtargets] Error 3

root@Linux:/home/qt/qt-everywhere-src-5.12.8# cat t.sh 
#!/bin/bash
./configure -prefix /usr/local/qt512 \
-confirm-license \
-opensource \
-release \
-no-opengl \
-v

解决方案：

添加配置选项：-skip qtdeclarative

root@Linux:/home/qt/qt-creator-opensource-src-4.11.2/build# cat ../../qt-everywhere-src-5.12.8/t.sh 
#!/bin/bash
./configure -prefix /usr/local/qt512 \
-confirm-license \
-opensource \
-release \
-no-opengl \
-skip qtdeclarative \
-v

此时./configure && make && make install，整个过程再无报错。。
