我正在尝试使用 npm 中的 node-gphoto2，但在 libgphoto2-2-dev 依赖项方面遇到了问题。我已经安装了它，但 pkg-config 说它不存在。
$ sudo aptitude search gphoto
p gphoto2 - The gphoto2 digital camera command-line c
p gphotofs - filesystem to mount digital cameras
i A libgphoto2-2 - gphoto2 digital camera library
i libgphoto2-2-dev - gphoto2 digital camera library (developme
p libgphoto2-dev-doc - gphoto2 digital camera library (developme
i A libgphoto2-l10n - gphoto2 digital camera library - localize
i A libgphoto2-port0 - gphoto2 digital camera port library
v libgphoto2port -
因此是的，报告 libgphoto2-2-dev 已安装，但是：
$ pkg-config --list-all | grep photo
libgphoto2_port libgphoto2_port - Device-independent access to serial, USB, and other ports
libgphoto2 libgphoto2 - Library for easy access to digital cameras
pkg-config 说不是。我需要做什么来诊断这个问题？我查看了相关问题，$PKG_CONFIG_PATH 是空白的。
编辑：这是构建中失败的行：
(pkg-config libgphoto2 || dpkg -s libgphoto2-2-dev || (echo 'ERROR: libgphoto2 seems not to be installed.' 1>&2; exit 1)) && node-gyp rebuild
