Python PyPy:无法使用pip安装sasl包

当我尝试使用安装

sasl

时

pypy -m pip install sasl

我得到以下错误

我在Centos 7上（Linux 3.10.0-693.17.1.el7.x86_64）。安装了以下软件包：cyrus sasl-devel、python-devel、openssl-devel、pypy-devel

> pypy --version
Python 2.7.10 (bbd45126bc691f669c4ebdfbd74456cd274c6b92, Jun 30 2016, 15:15:02) [PyPy 5.0.1 with GCC 4.8.5 20150623 (Red Hat 4.8.5-4)]

该功能仅从PyPy5.4开始得到支持。我建议您使用PyPy 6，这是PyPy项目下载页面

上的。它看起来像是给定的包C++扩展，我不确定它是否被PyPy支持（但我可能错了），如果你把它安装到CPython上会发生什么？你是指Cython？它已经安装（Centos包和pip包用于python和pypy）我的意思是带C实现的“传统”python，而不是pypy没有pypy的“pip安装sasl”，它解决了这个问题。我必须编译PyPy6才能在我的Centos版本上运行。
