Question

我正在尝试将3D功能添加到现有的Qt应用程序中。在我的project.pro文件中，我设置了QT变量：

TEMPLATE = subdirs
QT += 3dcore 3drender 3dinput 3dquick qml quick 3dquickextras
SUBDIRS = plugins/datasource \
          plugins/screenManager

qml.files = apps modules sysui i18n am-config.yaml Main*.qml
INSTALLS += qml

修改：我将QML_IMPORT_TRACE环境变量设置为1。现在，当我尝试运行应用程序时，我会看到以下内容：

Qt安装在/usr/local/Qt-5.7.0：

中

$ which qml
/usr/local/Qt-5.7.0/bin//qml
aras@aras-T900:~$ which qmake
/usr/local/Qt-5.7.0/bin//qmake

在我的.qml文件中，我尝试导入我需要的3D库：

import Qt3D.Core 2.0
import Qt3D.Render 2.0

然而，当我尝试运行我的应用程序时，我收到了这些错误：

...module "Qt3D.Render" is not installed
...module "Qt3D.Core" is not installed

我认为这就是我需要做的一切。我在这里缺少什么？

模块＆＃34; Qt3D.Core＆＃34;没有安装
