模块"；Qt3D.Core“；未安装

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

编辑：我将

QML\u导入跟踪

环境变量设置为

1

。现在，我在尝试运行应用程序时看到以下内容：

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，我尝试导入所需的三维库：

import Qt3D.Core 2.0
import Qt3D.Render 2.0

但是，当我尝试运行我的应用程序时，会出现以下错误：

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

---

我想这就是我所需要做的。我在这里遗漏了什么？

我通过从qt中查看最新的源代码并构建它，在我的qt应用程序中获得了3D效果。然后，当我遇到缺少模块的问题时，我构建了相应的模块。就3D而言，我就是这么做的：

cd qt3d
../qtbase/bin/qmake ../../qt5/qt3d
make -j5

---

这是假设一个源代码外目录生成。源代码位于

qt5

目录中。希望这有助于某人。

“我已经在QT安装中设置了包含$MQL2IXIPRONEPATH的路径”，这肯定是错误的——QML导入路径与C++包含的内容无关。此外，您不应该为了查找Qt附带的QML导入而设置env变量it。这是一个环境变量，所以在启动可执行文件时设置它。如果您使用的是Creator，请在项目窗格（左侧）中运行给定工具包的设置（顶部），并更改其中的环境。但关键是，您不需要为Qt本身附带的模块设置它。如果这些模块已安装但未找到，请将环境变量

QML\u IMPORT\u TRACE

设置为1，并检查是否确实找到了它们。您的Qt版本安装在哪里？您解决了这个问题吗？如果是..怎么做？Jiloc:我在我的解决方案中添加了一个答案
