CentOS解决pip 安装M2Crypto失败

请1我的

1	pip install M2Crypto

报错信息：

1 2 3 4 5 6

swig -python -I/usr/local/include/python2.7 -I/usr/include -includeall -o SWIG/_m2crypto_wrap.c SWIG/_m2crypto.i     /usr/include/openssl/opensslconf.h:31: Error: CPP #error ""This openssl-devel package does not work your architecture?"". Use the -cpperraswarn option to continue swig processing.     error: command 'swig' failed with exit status 1     ----------------------------------------     Command "/usr/local/bin/python -c "import setuptools, tokenize;__file__='/tmp/pip-build-_WW9OZ/M2Crypto/setup.py';exec(compile(getattr(tokenize, 'open', open)(__file__).read().replace('\r\n', '\n'), __file__, 'exec'))" install --r

或者报错：

1 2 3 4 5

swigging SWIG/_m2crypto.i to SWIG/_m2crypto_wrap.c swig -python -I/usr/include/python2.6 -I/usr/include -includeall -modern -builtin -outdir build/lib.linux-i686-2.6/M2Crypto -D__i386__ -o SWIG/_m2crypto_wrap.c SWIG/_m2crypto.i swig error : Unrecognized option -builtin Use 'swig -help' for available options. error: command 'swig' failed with exit status 1

以上都是swig的报错，原因是swig的版本过低导致的。
查看swig版本1.3.已经比较老旧了,swig -python -help 也未找到相关options：

1 2	[iyunv@localhost ~]# rpm -qa | grep swig swig-1.3.40-6.el6.x86_64

解决办法有两个：

• 升级swig版本
  
  

1 2 3 4 5

wget -O swig-3.0.7.tar.gz http://prdownloads.sourceforge.net/swig/swig-3.0.7.tar.gz tar zxf swig-3.0.7.tar.gz cd swig-3.0.7 ./configure --prefix=/usr make && make install

2.手动安装M2Crypto

1 2 3 4

[iyunv@localhost ~]#wget [iyunv@localhost ~]#unzip master.zip [iyunv@localhost ~]#cd M2Crypto-master [iyunv@localhost ~]#python setup.py install

success!
