我在使用 os x 和 heroku 上的 opencv 编译节点添加时遇到问题。但是，在 ubuntu 上它工作正常。
我正在使用流浪文件：
Vagrant.configure("2") do |config|
config.vm.box = "ubuntu/trusty64"
config.vm.provision :shell, :inline => $BOOTSTRAP_SCRIPT # see below
end
$BOOTSTRAP_SCRIPT = <<EOF
set -e # Stop on any error
# Make vagrant automatically go to /vagrant when we ssh in.
echo "cd /vagrant" | sudo tee -a ~vagrant/.profile
sudo apt-get update -y
sudo apt-get install -y build-essential python g++ make curl git
sudo apt-get install -y libopencv-dev libeigen3-dev
curl http://nodejs.org/dist/v0.10.35/node-v0.10.35-linux-x64.tar.gz | \
tar -C /usr/local/ --strip-components=1 -xvz; \
npm update -g npm
echo VAGRANT IS READY.
EOF
我有一个binding.gyp文件：
{
"targets": [{
"target_name": "module",
"sources": [
"node_src/module.cc",
"src/Candidate.cpp",
"src/Image.cpp",
"src/LearnerEngine.cpp",
"src/ShaheenTracker.cpp"
],
'libraries': [
'<!@(pkg-config --libs opencv)'
],
'include_dirs': [
'include/',
"<!(node -e \"require('nan')\")"
],
'cflags': [
'<!@(pkg-config --cflags "opencv <= 3.0.0" )', '-std=c++11', '-Wall', '-fPIC'
],
'cflags!': ['-fno-exceptions'],
'cflags_cc!': ['-fPIC', '-fno-rtti', '-fno-exceptions', '--enable-auto-import'],
"conditions": [
['OS=="mac"', {
'xcode_settings': {
'OTHER_CFLAGS': [
"-mmacosx-version-min=10.7",
"-std=c++11",
"-stdlib=libc++",
'<!@(pkg-config --cflags opencv)'
],
"GCC_ENABLE_CPP_RTTI": "YES",
"GCC_ENABLE_CPP_EXCEPTIONS": "YES"
}
}]
]
}]
}
在 OS X 上，我可以npm i正常编译。但是，我无法运行它，因为我收到以下错误：
1): Symbol not found: __ZNK2cv11_InputArray12getMatVectorERNSt3__16vectorINS_3MatENS1_9allocatorIS3_EEEE
在 Heroku 上，我使用https://github.com/ddollar/heroku-buildpack-apt来获取软件包并具有以下 Aptfile：
libeigen3-dev
libopencv-dev
但是，我收到以下错误：

我认为这是一个pkg-config问题。
我究竟做错了什么？
