项目错误：无法运行编译器“g++”。也许你忘了在 gitlab env 中设置环境

tra*_*eul 4 environment qmake g++ gitlab

我有一个奇怪的现象发生，我不知道如何调查。我希望有人已经遇到过这个并且可以提供提示

我正在使用 gitlab CI 来构建一些基于 Qt 的项目。gitlab runner 调用一个名为 build.sh 的脚本，当我在我的环境开发中以“我”的身份手动运行它时，它工作得很好。但是，runner 会引发一个错误，指出“项目错误：无法运行编译器‘g++’。也许您忘记设置环境”。所以我确保 g++ 可用（g++ -version 可以）并且在 g++ 中是在 PATH 但 pbm 仍然存在。

这是问题所在的脚本的一部分以及我进行的调查

echo ">>>>>> now generating makefiles for  ${PROJECT_FILE} <<<<<<"
export QTDIR=/usr/lib64/qt5
echo $QTDIR
echo QMAKESPEC is
qmake-qt5 -query QMAKE_SPEC
echo gcc version is
gcc --version
g++ --version

echo $PWD
whoami
$cmd_qMake -v
$cmd_qMake -makefile -o qMakefile ../src/${PROJECT_FILE}

echo PATH is $PATH
echo QMAKESPEC is
qmake-qt5 -query QMAKE_SPEC
echo gcc version is
gcc --version
g++ --version

这是输出（对不起；这是在调试模式下）

如您所见，g++ 似乎可以在跑步者的根路径下使用那么为什么 qMake 会失败？

谢谢你的帮助
