我正在尝试使用https://github.com/ddollar/heroku-buildpack-apt在heroku上安装phash。我想使用https://github.com/mgmtio/phash-image在我的node.js应用中使用它。
我目前有一个Aptfile：
cimg-dev
libphash0-dev
libmagickcore-dev
但是，我目前收到以下错误：

错误表示在pkg-config搜索路径中找不到包pHash。你应该添加包含`pHash.pc＆＃39;的目录。到PKG_CONFIG_PATH环境变量。 pHash的路径未设置。
尝试：
$ PKG_CONFIG_PATH=$PKG_CONFIG_PATH:/usr/local/lib/pkgconfig
$ export PKG_CONFIG_PATH
然后重建。
如果这不起作用
$ locate pHash.pc
这将为您提供pHash.pc的路径。使用路径（减去pHash.pc）并将其添加到PKG_CONFIG_PATH
$ export PKG_CONFIG_PATH= <path_here>
