安装pip之前需要先安装zlib,setuptools
安装zlib
#yum -y install zlib报错了,如下:
No module named yum
这个错误的原因是我升级了python,导致yum无法使用。
参考文档 :http:

解决办法:
# vi /usr/bin/yum
#!/usr/bin/python_old
/
/
文件第一行内容改为
#!/usr/bin/python_old,因为我把旧的python重命名为python_old了。而yum匹配的是旧的python。
# /sbin/service yum-updatesd restart
# yum -y install zlib zlib-devel
/
/
安装成功!但是安装setuptools依旧报错。需要重新编译python。

下面重新编译python
# cd /usr/local/Python-2.7.10
# ./configure --prefix=/usr/local/Python2.7
#make && make install
安装setuptools
# cd /usr/local
# curl -O https://pypi.python.org/packages/source/s/setuptools/setuptools-2.0.tar.gz
# tar zxvf setuptools-2.0.tar.gz
# cd setuptools-2.0
#python setup.py build
#python setup.py install//成功
安装PIP
PIP官网 https:
/
/
pypi.python.org
/
pypi
/
pip
#cd /usr/local
# curl -O https://pypi.python.org/packages/source/p/pip/pip-7.1.2.tar.gz#md5=3823d2343d9f3aaab21cf9c917
# curl -O https://pypi.python.org/packages/source/p/pip/pip-7.1.2.tar.gz
用wget下载时会报错,这里改用curl
-
O即可,这
2
个命令下载的包都是对的
# tar zxvf pip-7.1.2.tar.gz
# cd pip-7.1.2
# python setup.py install
# ln -s /usr/local/Python2.7/bin/pip /usr/bin/pip
/
/
pip默认安装到了
/
usr
/
local
/
Python2.

/
bin
/
下面
#pip //测试pip
报错啦:ImportError: cannot
import
name HTTPSHandler
原因在于openssl,openssl
-
devel两个文件包未正确安装
解决办法:
#yum install openssl openssl-devel -y
继续报错,然后我重新编译了python和pip。OK不再报错了。
备注:升级安装之前先用yum安装zlib、zlib-devel、openssl、openssl-devel。
然后在
进入python安装包,找到Setup文件,用 vi 打开
- cd Python-2.7.11/Modules
- vi Setup.dist
找到
- # Socket module helper for SSL support; you must comment out the other
- # socket line above, and possibly edit the SSL variable:
- #SSL=/usr/local/ssl#_ssl _ssl.c \
- # -DUSE_SSL -I$(SSL)/include -I$(SSL)/include/openssl \
- # -L$(SSL)/lib -lssl -lcrypto
把前面的 # 号去掉,修改为
- # Socket module helper for SSL support; you must comment out the other
- # socket line above, and possibly edit the SSL variable:
- SSL=/usr/local/ssl
- _ssl _ssl.c \
- -DUSE_SSL -I$(SSL)/include -I$(SSL)/include/openssl \ -L$(SSL)/lib -lssl -lcrypto
保存退出,
去掉ssl、zlib相关注释,使模块生效。
