2) 準(zhǔn)備基礎(chǔ)環(huán)境

2.1) 安裝setuptools

?

1234567891011121314151617181920212223242526

cd ~/Env/pythonwget http://pypi.douban.com/packages/source/s/setuptools/setuptools-3.3.tar.gz? # 豆瓣源tar zxvf setuptools-3.3.tar.gzcd setuptools-3.3python setup.py buildsudo python setup.py install# 或者用ez_setup.py，同樣改為豆瓣源# wget https://bitbucket.org/pypa/setuptools/raw/bootstrap/ez_setup.py# python ez_setup.py --download-base http://pypi.douban.com/packages/source/s/setuptools/# 缺少zlib，安裝setuptools時(shí)出錯(cuò)。# issue: RuntimeError: Compression requires the (missing) zlib moduleyum install zlib zlib-devel -y# 重make Python2.7再安裝cd ../Python-2.7.6make? # 這時(shí)才注意先前make時(shí)缺了好多模塊make install# 環(huán)境變量vi /etc/profile# 添加如下內(nèi)容：# PY_HOME=/usr/local/py-2.7.6# export PATH=$PY_HOME/bin:$PATHsource /etc/profile? # 當(dāng)前終端生效，reboot后才會(huì)完全生效echo $PATH

2.2) 安裝pip

?

1234567891011121314

easy_install -i http://pypi.douban.com/simple pip# 缺少ssl模塊，pip使用時(shí)出錯(cuò)# issue: ImportError: cannot import name HTTPSHandleryum install openssl openssl-devel -ymake? # Python-2.7.6目錄make install# 配置pip為豆瓣源mkdir ~/.pip? # ls或ll -a 查看隱藏內(nèi)容vi ~/.pip/pip.conf# 添加如下內(nèi)容：# [global]# index-url = http://pypi.douban.com/simple

2.3) 安裝virtualenv

?

123	supip install virtualenvpip install virtualenvwrapper

virtualenv用于創(chuàng)建隔離的Python運(yùn)行環(huán)境，依賴不同庫(kù)和版本時(shí)避免混亂。

virtualenvwrapper為virtualenv上的擴(kuò)展，提供更方便的命令。
