Question

QtCreator不想创建我的ui头文件。当我在终端输入uic时，它会告诉我：

louis@Krusty:~$ uic
uic: could not exec '/usr/lib/x86_64-linux-gnu/qt4/bin/uic': No such file or directory

我在我的主文件夹中安装了Qt5，Qt认出它没有问题。在设置中，它位于好文件夹中。 Normaly它不应该有任何问题！但它有，所以我必须手工创建我的表格：

./.Qt/5.5/gcc_64/bin/uic Documents/lab/Qt/OpenPlane/AirplaneEditor.ui  -o ui_AirplaneEditor.h

这是我的QMake：

QT += widgets

SOURCES += \
    main.cpp \
    Airplane.cpp \
    AirplaneOverview.cpp \
    AirplaneManager.cpp \
    AirplaneEditor.cpp

HEADERS += \
    Airplane.h \
    AirplaneOverview.h \
    AirplaneManager.h \
    AirplaneEditor.h \
    ui_AirplaneEditor.h # By hand

FORMS += \
    AirplaneEditor.ui

如果您需要更多信息，请问我！

来自@bibi的有用评论：

您的PATH看起来不包含~/.Qt/5.5/gcc_64/bin/，和/或不在常规路径之前。正如bibi所说，“which qmake uic”的输出是什么？

在终端上输入：

export PATH=$HOME/.Qt/5.5/gcc_64/bin/:$PATH

（可能需要其他一些路径）然后从此终端运行agin。如果确实如此，请将此PATH添加添加到~/.bashrc以使其永久化。

但我看到的根本问题是为什么你手动安装了Qt5 ??? （以及隐藏目录中的原因？）我确实需要一个自定义版本的Qt，它不会安装在您的系统文件中，更好的安装位置可能是/opt。加上上面解释的匹配PATH设置。

如果您不需要自定义Qt，每个Linux发行版都可以愉快地安装Qt4和Qt5，然后您可以选择在.pro文件中使用哪个版本，如下所示：

How to check the selected version of Qt in a .pro file?

编辑：

“我是用Qt的官方安装程序安装的。我该怎么办？在Ubuntu 15.10上安装它？“

常规方式绝对不是从某些Qt的档案中安装它。你有一个包装商/维护者的分销，你应该信任他们。所以对于Qt4安装，sudo apt-get install qt-sdk。对于Qt5，我不知道，但有点apt-cache search qt5和/或谷歌搜索应该做的伎俩。

对于Qt5安装，至少在我的虚拟机Ubuntu 14-04（我运行Debian）上，基本包就像qtbase5-dev：

查看它将安装的依赖项列表：qt5-qmake，qtbase5-dev-tools，libs等。

所以apt-get install，根据你想要开发的Qt5应用程序的类型，加上后者可能还有几个包（例如Qt5与dbus或者这个或那个）。

Answer 2

我遇到了同样的问题。我的所有Qt5软件包都已安装，但我的linux（CentOS）系统上找不到uic，但uic-qt5是！

因此执行以下操作对我有用：

$ uic-qt5 AirplaneEditor.ui -o ui_airplaneeditor.h

没有使用uic生成的标头
