Question

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

原始项目没有显示任何错误。我清理并重建了所有东西，但没有解决。该项目可以编译并完美运行，因此QtCreator愚蠢地认为存在一些问题。

这可能是什么原因？我正在使用Qt 5.11，QtCreator 4.7.1

# The following define makes your compiler emit warnings if you use

# depend on your compiler). Please consult the documentation of the

# 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。该警告消息的大致含义是：“请将/usr/lib64/qt/qml添加到您的QML_IMPORT_PATH变量中。”

在我的项目中进行的快速搜索在项目的.pro文件中仅发现QML_IMPORT_PATH的一个实例。我将建议的路径添加到.pro文件中的该行，问题已解决。

YMMV

找不到QML模块
