pygobject-2.28.6 无法配置：找不到包“gobject-introspection-1.0”，如何解决？

Question

我正在尝试让 pygobject-2.28.6 在 cygwin 中编译（存储库中的版本是 2.28.4，有一些问题）。这是 ./configure 的尾部：

checking for GLIB - version >= 2.24.0... yes (version 2.34.3)
checking for ffi... checking for FFI... yes
checking for GIO... yes
checking for GIOUNIX... yes
checking for GI... no
configure: error: Package requirements (glib-2.0 >= 2.24.0
        gobject-introspection-1.0 >= 0.10.2
    ) were not met:

No package 'gobject-introspection-1.0' found

Consider adjusting the PKG_CONFIG_PATH environment variable if you
installed software in a non-standard prefix.

Alternatively, you may set the environment variables GI_CFLAGS
and GI_LIBS to avoid the need to call pkg-config.
See the pkg-config man page for more details.

我安装了 gobject-introspection 1.34.2-3。正如这里所见：

$ whereis gobject-introspection
gobject-introspection: /lib/gobject-introspection /usr/lib/gobject-introspection

还有这里

$ whereis gobject-introspection-1.0
gobject-introspection-1: /usr/share/gobject-introspection-1.0

我尝试将configure =中的GI_CFLAGS和GI_LIBS设置为/ lib /和/ usr / lib /（甚至/ usr / share /）但无济于事。我还能做什么来尝试解决这个问题？谢谢您的宝贵时间！

Answer 1

您可能缺少开发包。 软件包名称因发行版而异，但包含

/usr/lib/pkgconfig/gobject-introspection-1.0.pc

（对于某些 64 位发行版则包含

/usr/lib64/pkgconfig/gobject-introspection-1.0.pc

）：

• Fedora、CentOS、RHEL、等：gobject-introspection-devel
• Debian、Ubuntu、Mint、等：libgirepository1.0-dev
• Arch：g对象内省
• FreeBSD：g对象内省
• Cygwin：libgirepository1.0-devel
• msys2：mingw-w64-x86_64-gobject-introspection和/或mingw-w64-i686-gobject-introspection

Answer 2

我在 cygwin 上编译了这个。您需要的包裹是：

libgirepository1.0-devel

.

在 Ubuntu 中称为

libgirepository1.0-dev

Answer 3

对于 macOS {我的是（intel cpu）}：

 brew install pygobject3 gtk+3
 pip install --no-use-pep517 PyGObject

它在 python 2.7 虚拟环境中运行。

Answer 4

我没有足够的代表来发表评论，所以这实际上是 Nemequ 答案的附录：

• MSYS2：mingw-w64-x86_64-gobject-introspection和/或mingw-w64-i686-gobject-introspection

      Package gobject-introspection-1.0 was not found in the pkg-config search path.
      Perhaps you should add the directory containing `gobject-introspection-1.0.pc'
      to the PKG_CONFIG_PATH environment variable
      Package 'gobject-introspection-1.0', required by 'virtual:world', not found

  note: This error originates from a subprocess, and is likely not a problem with pip.
  ERROR: Failed building wheel for pygobject
Failed to build pygobject
ERROR: Could not build wheels for pygobject, which is required to install pyproject.toml-based projects

没有提到“gobject-introspection-1.0”，但是这个doc提到了命令设置

gobject-introspection

并顺利解决了我的问题。

sudo pacman -S --noconfirm python-wheel
sudo pacman -S --noconfirm base-devel openssl zlib git gobject-introspection

在 Ubuntu 中：

$> sudo apt install libgirepository1.0-dev
