qt - 未找到 QML 模块

Question

我将一个项目复制到另一个目录( fork )，现在我总是得到 QML module not found (QtQuick.Controls). , 和类似的。

原始项目没有显示任何错误。我清理并重建了所有东西，但这并没有解决它。该项目编译并运行完美，因此 QtCreator 不知何故被愚弄了，认为存在一些问题。

这可能是什么原因？我正在使用 Qt 5.11、QtCreator 4.7.1

见附图



项目文件:

QT += quick network
QT += quickcontrols2
QT += widgets
CONFIG += c++11

# The following define makes your compiler emit warnings if you use
# any feature of Qt which as been marked deprecated (the exact warnings
# depend on your compiler). Please consult the documentation of the
# deprecated API in order to know how to port your code away from it.
DEFINES += QT_DEPRECATED_WARNINGS

# You can also make your code fail to compile if you use deprecated APIs.
# In order to do so, uncomment the following line.
# You can also select to disable deprecated APIs only up to a certain version of Qt.
#DEFINES += QT_DISABLE_DEPRECATED_BEFORE=0x060000    # disables all the APIs deprecated before Qt 6.0.0

Answer 1

我也遇到了这个问题并且能够解决它，主要是按照警告消息中的说明进行操作。该警告消息的粗略近似表示:“请将 /usr/lib64/qt/qml 添加到您的 QML_IMPORT_PATH 变量中。”

在我的项目中快速搜索发现只有一个 QML_IMPORT_PATH 的实例在项目的 .pro 文件中。我在 .pro 文件中添加了该行的建议路径，问题得到解决。
