python buildpack - fatal error: sasl/sasl.h: No such file or directory

Question

我在我的 Bluemix 应用程序中安装 sasl 时遇到以下错误：

我正在使用构建包：python 1.5.5

我的 runtime.txt 包含：python-3.5.0

如何在 buildpack 中安装必要的头文件？

更新：

最新的 cloud foundry 堆栈似乎有 sasl 库：https://github.com/cloudfoundry/cflinuxfs2/blob/1.119.0/cflinuxfs2/build/install-packages.sh#L98。

我如何在 Bluemix 上使用这个堆栈？

我的解决方案是使用 pure-sasl 并从应用程序代码安装 imypla 和 thrift_sasl 而不是我的 requirements.txt:

try:
    import impyla 
except ImportError:
    print("Installing missing impyla")
    import pip
    pip.main(['install', '--no-deps', 'impyla'])

try:
    import thrift_sasl
except ImportError:
    print("Installing missing thrift_sasl")
    import pip
    # need a patched version of thrift_sasl.  see https://github.com/cloudera/impyla/issues/238
    pip.main(['install', '--no-deps',  'git+https://github.com/snowch/thrift_sasl'])

我将此代码添加到我的烧瓶应用程序的视图中：https://github.com/snowch/movie-recommender-demo/blob/master/web_app/app/main/views.py

也许你应该安装一些系统库才能安装sasl参考https://pypi.python.org/pypi/sasl/0.1.3

This library contains C++ code, and will require some additional system libraries installed.

Debian/Ubuntu

apt-get install python-dev libsasl2-dev gcc

CentOS/RHEL

yum install gcc-c++ python-devel.x86_64 cyrus-sasl-devel.x86_64

我遇到了类似的错误 -

In file included from sasl/saslwrapper.cpp:254:0:
sasl/saslwrapper.h:22:23: fatal error: sasl/sasl.h: No such file or directory
#include <sasl/sasl.h>
                       ^
compilation terminated.
error: command 'gcc' failed with exit status 1

试试这个帖子，它对我很有帮助 I can't install python-ldap
