当我构建其他人的代码时，它显示“在 pkg-config 搜索路径中找不到软件包 Qt5Gui”，但我安装了它
我已经安装了Qt 5.1.4，但是当我“make install”时，它显示
Package Qt5Gui was not found in the pkg-config search path.
Perhaps you should add the directory containing `Qt5Gui.pc'
to the PKG_CONFIG_PATH environment variable
No package 'Qt5Gui' found
Package Qt5Widgets was not found in the pkg-config search path.
Perhaps you should add the directory containing `Qt5Widgets.pc'
to the PKG_CONFIG_PATH environment variable
No package 'Qt5Widgets' found
Package Qt5Multimedia was not found in the pkg-config search path.
Perhaps you should add the directory containing `Qt5Multimedia.pc'
to the PKG_CONFIG_PATH environment variable
No package 'Qt5Multimedia' found
但是我安装了这个软件qt-opensource-linux-x64-5.14.0.run，之后我试图找到它们，我运行了 locate Qt5Gui 但没有返回 Qt5Gui.pc，那么我如何在我的设备上获取 Qt5*.pc ubuntu 20.04 ？
I have installed Qt 5.1.4 but when I 'make install' it shows

But I installed this software qt-opensource-linux-x64-5.14.0.run, after I tried to find them I ran locate Qt5Gui but no Qt5Gui.pc returned,so how can i get Qt5*.pc on my ubuntu 20.04 ?

我开始的安装还少了几个包
完整的安装应该是这样的
qt编译环境的搭建需要的不仅仅是从官网下载的安装包
它对我有用！
现在我可以找到
Qt5*.pc！The installation I started was missing a few more packages
The complete installation should look like this
The construction of the qt compilation environment requires more than the installation package downloaded from the official website
It worked for me !
Now i can find the
Qt5*.pc!您需要安装 qtbase5-dev 它是 qt5-default
参见：https://packages.ubuntu.com/bionic/amd64/qtbase5-dev/filelist< /a>
编辑：您可能还需要安装包 qtmultimedia5-dev。
You need to install qtbase5-dev which is part of qt5-default
see: https://packages.ubuntu.com/bionic/amd64/qtbase5-dev/filelist
EDIT: you may also have to install the package qtmultimedia5-dev.
