问题描述

我有一个用Python2编写的旧程序需要使用，但它与Ubuntu Xenial的依赖项相处不好。

我必须手动获取这些才能使其运行：

libwebp6_0.6.1-2ubuntu0.18.04.1_amd64.deb
libwebpdemux2_0.6.1-2ubuntu0.18.04.1_amd64.deb
libwebpmux3_0.6.1-2ubuntu0.18.04.1_amd64.deb
python-pil_5.1.0-1ubuntu0.7_amd64.deb
python-gtk2_2.24.0-5.1ubuntu2_amd64.deb

当我运行它时，我得到这样的结果：

myprog.py:12: PyGIWarning: Gtk was imported without specifying a version first. Use gi.require_version('Gtk', '3.0') before import to ensure that the right version gets loaded.

后跟

GLib.Error: ... Required gtk+ version 3.20, current version is 3.18 (7)

使用gi.require_version('Gtk', '3.20')会导致ValueError: Namespace Gtk not available for version 3.20。

我认为Xenial上没有针对Python2的GTK3。

我能找到的最新python-gtk2是从Bionic安装的。所以我在安装了一堆依赖项后，编译了pybgobject3.20：

export GI_LIBS="-L/usr/lib/x86_64-linux-gnu -lglib-2.0"
export GI_CFLAGS="-I/usr/include/glib-2.0 -I/usr/include/glib-2.0/include"
export PYCAIRO_CFLAGS="-I/usr/include/pycairo"
export CPPFLAGS="-I/usr/include/gobject-introspection-1.0"
./configure --prefix=${MY_BASE}/build --enable-static --enable-shared --with-python=python2

并尝试使用LD_LIBRARY_PATH=${MY_BASE}/build python2 myprog.py运行它，但遇到了相同的问题。我尝试了各种变化，直到LD_LIBRARY_PATH=${MY_BASE}/build/lib/python2.7/site-packages，结果相同。

我是不是编译错了包？我错过了什么？

这些是我目前安装的包：

$ apt list --installed|grep python|grep -v python3

推荐答案

我后来让它在Xenial上运行，但这个应用程序不能正常工作：文件、编辑、...例如，菜单选项不起作用。

根据我不断增长的笔记，我通过编译pygobject-3.20.1.tar.xz使其工作，

export GI_LIBS="-L/usr/lib/x86_64-linux-gnu -lglib-2.0"
export GI_CFLAGS="-I/usr/include/glib-2.0 -I/usr/include/glib-2.0/include"
export PYCAIRO_CFLAGS="-I/usr/include/pycairo"
export CPPFLAGS="-I/usr/include/gobject-introspection-1.0"
./configure --prefix=${PWD}/build/linux/x86_64 --enable-static --enable-shared --with-python=python2  

但我不确定这是我所遵循的路径，并且我在一个临时目录中。

不管怎样，现在我在Windows VM中遇到了同样的问题。
