Question

我正在尝试在heroku上安装自定义版本，因此我使用各种方法尝试使用buildpack安装第三部分。在我的.buildpacks文件中，我有：

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

并在我的Aptfile我有以下内容：libgeoip-dev这是geoip的先决条件，它与requirements.txt（GeoIP==1.3.2）一起安装

以下是我的环境变量：

remote: C_INCLUDE_PATH is /app/.heroku/vendor/include:/app/.heroku/vendor/include:/app/.heroku/python/include
remote: CPATH is /tmp/build_xxxxx/.apt/usr/include:
remote: LD_LIBRARY_PATH is /app/.heroku/vendor/lib:/app/.heroku/vendor/lib:/app/.heroku/python/lib

我收到的错误消息是：

remote:        building 'GeoIP' extension
remote:        creating build
remote:        creating build/temp.linux-x86_64-2.7
remote:        gcc -pthread -fno-strict-aliasing -g -O2 -DNDEBUG -g -fwrapv -O3 -Wall -Wstrict-prototypes -fPIC -I/app/.heroku/python/include/python2.7 -c py_GeoIP.c -o build/temp.linux-x86_64-2.7/py_GeoIP.o -fno-strict-aliasing
remote:        creating build/lib.linux-x86_64-2.7
remote:        gcc -pthread -shared build/temp.linux-x86_64-2.7/py_GeoIP.o -lGeoIP -o build/lib.linux-x86_64-2.7/GeoIP.so
remote:        /usr/bin/ld: cannot find -lGeoIP
remote:        collect2: error: ld returned 1 exit status
remote:        error: command 'gcc' failed with exit status 1

解决这个问题最聪明的方法是什么？即我想我无法改变软件包管理器的安装位置。有办法解决这个问题吗？

# Prepend proper path buildpack use.
export PATH=$BUILD_DIR/.heroku/python/bin:$BUILD_DIR/.heroku/vendor/bin:$PATH

heroku-buildpack-python buildpack与heroku-buildpack-apt buildpack的搭配不是很好，因为它会将gcc的重要变量用于链接你的python扩展名与geoip lib。在问题跟踪器上提交错误。

我天真地通过修改heroku-buildpack-python的编译脚本来解决类似的问题，以便不设置LD_LIBRARY_PATH和INCLUDE_PATH，以及在导出期间附加当前的LD_LIBRARY_PATH和INCLUDE_PATH变量，以便不覆盖它们。
