CentOS7 安装使用pypy5

1 安装系统环境及及pypy

rpm -ivh http://dl.fedoraproject.org/pub/epel/7/x86_64/e/epel-release-7-6.noarch.rpm

rpm –import /etc/pki/rpm-gpg/RPM-GPG-KEY-EPEL-7

yum -y install nginx mysql-libs mysql-devel python-setuptools

yum -y install pypy-libs pypy pypy-devel

2、安装pip

wget –no-check-certificate https://bootstrap.pypa.io/ez_setup.py -O - | python

wget –no-check-certificate https://bootstrap.pypa.io/ez_setup.py -O - | pypy

wget https://pypi.python.org/packages/e7/a8/7556133689add8d1a54c0b14aeff0acb03c64707ce100ecd53934da1aa13/pip-8.1.2.tar.gz#md5=87083c0b9867963b29f7aba3613e8f4a

tar -zxvf pip-8.1.2.tar.gz

cd pip-8.1.2

python setup.py install

pypy setup.py install

3、使用pypy及模块安装：

执行： pypy pythonfile.py （跟python用法一样）

模块安装： pypy -m pip install modulename

numpy安装略有不同：

详见：http://pypy.org/download.html#installing

到2016/06/07，numpy对pypy3的支持还没有很好：

For now, NumPyPy does not work with PyPy3*, and is not complete. You may get warnings or NotImplemented errors. Please let us know if you get crashes or wrong results.

附：关于哪些模块能在pypy里正常安装，哪些不能，官方给了列表，蓝的表示可以，红的表示失败。
