跟随 How do I Install GTK+ 3.0? - Ask Ubuntu 并将 Gtk 安装到 ubuntu
sudo apt-get install libgtk-3-dev
但是还是报同样的错误
如何解决我的问题？

您需要安装 gobject-introspection, python3-gi and gir1.2-gtk-3.0，这些软件包包括将 GTK+ 库公开给 python3 的文件。
sudo apt install python3-gi gobject-introspection gir1.2-gtk-3.0
对于 CENTOS (7)/OpenSUSE (15.1)，您必须分别在 dnf/yum/zypper 中将软件包 gir1.2-gtk-3.0 替换为 gtk3-devel - 谢谢 bgStack.

debian\ubuntu 中的 xyz-dev 包调用包含 C 头文件、pkg-config 文件和自动工具宏。仅当您打算使用 C 和 C++ 等编译语言构建软件时才需要这些。
这些都安装到：
/usr/include/../xyz/header1.h # headers
/usr/include/../xyz/header2.h
...
/usr/lib/x86_64-linux-gnu/pkgconfig/libxyz.pc # pkgconfig files
...
/usr/share/aclocal/xyz.m4 # autotools macros
使用dpkg -L libgtk-3-dev查看此软件包安装在您系统上的所有文件。
