heroku - 在 heroku 上的 node.js 应用程序中使用 Magick++

Question

我正在尝试将 Node 应用程序推送到 heroku，但我正在使用 imagemagick-native似乎 Heroku 在使用 Magick++ 时遇到了问题——我尝试使用自定义构建包，但似乎找不到支持 Magick++ 的构建包。 (1) 这是问题吗 (2) 有没有办法在 Heorku 上运行 Magick++？

Answer 1

我在这方面取得了一些进展:

使用 multi buildpack :

heroku config:set BUILDPACK_URL=https://github.com/ddollar/heroku-buildpack-multi.git

以便它可以加载 apt-buildpack除了nodejs之一。在 .buildpacks 中列出您的 builpacks :

https://github.com/ddollar/heroku-buildpack-apt.git
https://github.com/heroku/heroku-buildpack-nodejs.git

现在安装 libmagick++-dev通过 apt 将其列在名为 Aptfile 的文件中.

现在，如果您在 package.json 中包含 imagemagick-native :

"dependencies": {
    "imagemagick-native": "1.7.0"
}

它将开始编译。虽然 $CPATH由 APT 包正确设置， node-gyp不知何故似乎没有将它转发给gcc。

这会导致以下错误:

remote:        > imagemagick-native@1.7.0 install /tmp/build_720834c3a32b65d69ae603d7c618e20f/node_modules/imagemagick-native
remote:        > node-gyp rebuild
remote:        
remote:        make: Entering directory `/tmp/build_720834c3a32b65d69ae603d7c618e20f/node_modules/imagemagick-native/build'
remote:          CXX(target) Release/obj.target/imagemagick/src/imagemagick.o
remote:        In file included from ../src/imagemagick.cc:9:
remote:        ../src/imagemagick.h:1:22: warning: Magick++.h: No such file or directory

所以它还没有解决问题，但我认为它在正确的轨道上。仍在试图弄清楚 node-gyp 是怎么回事。

更新

要解决该问题，请派生 nodejs buildpack 并将以下几行添加到 bin/compile 的顶部:

path=`echo "$INCLUDE_PATH" | cut -d : -f 1`
export CXX="`which g++` -I$path/ImageMagick"

适用于 cedar-14 .对于已弃用的 cedar您需要使用 imagemagick-native v1.22。
