"module QtQuick is not installed" 使用 windeployqt 发布版本时出错

Question

我有一个简单的 Qt 5.11 x64 项目，MSVC 2017 编译器，默认构建设置由 Qt Creator 4.7 创建。

它工作正常，但是当我添加 windeployqt 以复制发布版本中的所有 Qt dll 时，我收到错误消息（来自 Qt Creator 的运行）

QQmlApplicationEngine failed to load component
qrc:/qml/main.qml:1 module "QtQuick" is not installed

QML 文件有

import QtQuick 2.7

.pro

QT += quick widgets xml
CONFIG += c++11

CONFIG += precompile_header
PRECOMPILED_HEADER = stdafx.h

CONFIG -=  embed_manifest_exe
RC_FILE = app-uac.rc


DEFINES += QT_DEPRECATED_WARNINGS

DESTDIR=bin

SOURCES += main.cpp \
    ..........

RESOURCES += qml.qrc \
    img.qrc \
    font.qrc

# Default rules for deployment.
qnx: target.path = /tmp/$${TARGET}/bin
else: unix:!android: target.path = /opt/$${TARGET}/bin
!isEmpty(target.path): INSTALLS += target

HEADERS += \
    .........
    stdafx.h

OTHER_FILES += \
    app-uac.exe.manifest \
    app-uac.rc \
    app_info.xml

LIBS += -L"C:/Program Files (x86)/Windows Kits/10/Lib/10.0.17134.0/um/x64/" -lUser32 -lAdvAPI32

TARGET_CUSTOM_EXT = .exe

CONFIG(release, debug|release) {
    DEPLOY_COMMAND = $$[QT_INSTALL_BINS]/windeployqt --release --compiler-runtime

    DEPLOY_TARGET = $$shell_quote($$shell_path($${OUT_PWD}/$${DESTDIR}/$${TARGET}$${TARGET_CUSTOM_EXT}))

    QMAKE_POST_LINK += $${DEPLOY_COMMAND} $${DEPLOY_TARGET}
}

windeployqt输出

Answer 1

看起来它适用于 --qmldir 参数。

$$[QT_INSTALL_BINS]/windeployqt --release --compiler-runtime  --qmldir $$shell_quote($$shell_path($$PWD/qml))
