为什么Qt Creator无法识别Qt安装目录？

Question

我刚刚构建了Qt 5.15和Qt Creator (在Mac OS上)。在第一次启动时，Qt Creator会提示您“选择Qt安装”。

默认情况下(在Mac上)，Qt安装到/usr/local/Qt-(版本)。但是，此对话框似乎无法将此目录或任何子目录识别为安装目录。

qmake -query返回以下内容，其中任何一个似乎都不能作为“安装”目录。qmake所在的目录也不存在。

QT_SYSROOT:
QT_INSTALL_PREFIX:/usr/local/Qt-5.15.0
QT_INSTALL_ARCHDATA:/usr/local/Qt-5.15.0
QT_INSTALL_DATA:/usr/local/Qt-5.15.0
QT_INSTALL_DOCS:/usr/local/Qt-5.15.0/doc
QT_INSTALL_HEADERS:/usr/local/Qt-5.15.0/include
QT_INSTALL_LIBS:/usr/local/Qt-5.15.0/lib
QT_INSTALL_LIBEXECS:/usr/local/Qt-5.15.0/libexec
QT_INSTALL_BINS:/usr/local/Qt-5.15.0/bin
QT_INSTALL_TESTS:/usr/local/Qt-5.15.0/tests
QT_INSTALL_PLUGINS:/usr/local/Qt-5.15.0/plugins
QT_INSTALL_IMPORTS:/usr/local/Qt-5.15.0/imports
QT_INSTALL_QML:/usr/local/Qt-5.15.0/qml
QT_INSTALL_TRANSLATIONS:/usr/local/Qt-5.15.0/translations
QT_INSTALL_CONFIGURATION:/Library/Preferences/Qt
QT_INSTALL_EXAMPLES:/usr/local/Qt-5.15.0/examples
QT_INSTALL_DEMOS:/usr/local/Qt-5.15.0/examples
QT_HOST_PREFIX:/usr/local/Qt-5.15.0
QT_HOST_DATA:/usr/local/Qt-5.15.0
QT_HOST_BINS:/usr/local/Qt-5.15.0/bin
QT_HOST_LIBS:/usr/local/Qt-5.15.0/lib
QMAKE_SPEC:macx-clang
QMAKE_XSPEC:macx-clang
QMAKE_VERSION:3.1
QT_VERSION:5.15.0

有人知道这东西在找什么吗？谢谢!

此对话框对此任务似乎不可用。文档也不正确或不完整。

要将Qt Creator指向自建Qt安装，您必须转到它的Preferences / Kits页面并按Add；然后导航到Qt安装目录，进入bin子目录，并选择qmake可执行文件，正如Frank指出的那样。
