按照这个说明：http://npmjs.org/package/canvas
我已经安装了 cairo 和 pixman，但是 cairo 找不到 pixman。
Package pixman-1 was not found in the pkg-config search path.
Perhaps you should add the directory containing `pixman-1.pc'
to the PKG_CONFIG_PATH environment variable
No package 'pixman-1' found
gyp: Call to 'pkg-config pixman-1 --libs' returned exit status 1. while trying to load binding.gyp
我的 cairo.pc 看起来像这样：
prefix=/usr
exec_prefix=${prefix}
libdir=${exec_prefix}/lib
includedir=${prefix}/include
Name: cairo
Description: Multi-platform 2D graphics library
Version: 1.12.14
Requires.private: gobject-2.0 glib-2.0 pixman-1 >= 0.30.0 fontconfig >= 2.2.95 freetype2 >= 9.7.3 libpng xrender >= 0.6 x11
xext
Libs: -L${libdir} -lcairo
Libs.private: -lz -lz
Cflags: -I${includedir}/cairo
现在看看当我编辑 PKG_CONFIG_PATH 时发生了什么……
和：
PKG_CONFIG_PATH=/opt/X11/lib/pkgconfig
[root@vps ~]# npm install canvas
npm http GET https://registry.npmjs.org/canvas
npm http 304 https://registry.npmjs.org/canvas
> [email protected] install /lib/node_modules/canvas
> node-gyp rebuild
Package pixman-1 was not found in the pkg-config search path.
Perhaps you should add the directory containing `pixman-1.pc'
to the PKG_CONFIG_PATH environment variable
No package 'pixman-1' found

答案1
感谢您的提问，我找到了解决方案。
[server]$ ./configure --prefix=$HOME/test
[server]$ make
[server]$ make install
[server]$ ls -R ~/test/
~/test/:
include lib
~/test/include:
pixman-1
~/test/include/pixman-1:
pixman-version.h pixman.h
~/test/lib:
libpixman-1.a libpixman-1.so libpixman-1.so.0.32.4
libpixman-1.la libpixman-1.so.0 pkgconfig
~/test/lib/pkgconfig:
pixman-1.pc
我所需要的是
$ export PKG_CONFIG_PATH="$HOME/lib/pkgconfig/"
然后pkg-config pixman-1 --libs返回了正确的库并且我可以让 cairo 进行编译。
也许 pkg-config 找不到 pixman：您可以尝试设置环境变量来覆盖 pkg-config
pixman_CFLAGS - pixman 的 C 编译器标志，覆盖 pkg-config
pixman_LIBS - pixman 的链接器标志，覆盖 pkg-config
$ export pixman_CFLAGS="-I$HOME/include/pixman-1"
$ export pixman_LIBS="-L$HOME/lib/ -lpixman-1"
答案2
简单复制pixman.h和pixman-版本.h从pixman-1文件夹放入上层文件夹中包括。
现在你可以运行制作命令，它就像魔法一样起作用。
答案3
您需要安装 pixman dev 库 - 这些说明似乎遗漏了这一点。
# apt-get install libpixman-1-dev
答案4
我在 Debian 上遇到了这个错误，安装所需的软件包（build-essential libcairo2-dev libpango1.0-dev libjpeg-dev libgif-dev librsvg2-dev）并没有修复它。最后我发现切换我正在运行的 python 和 node 版本可以修复它。它与 Python 3.9 或 Node 15 配合不好。这是工作配置：
> python --version
Python 3.8.6
> node -v
v14.15.4
> npm -v
6.14.11
