安装系统后python版本低 需要更新更高版本
wget https://www.python.org/ftp/python/2.7.9/Python-2.7.9.tgz
tar zxvf Python-2.7.9.tgz ./configure make install make mv /usr/bin/python /usr/bin/python_old ln -s /usr/local/bin/python2.7 usr/bin/
修改yum配置文件以保证yum可用
vim /usr/bin/yum #!/usr/bin/python #修改此处为/usr/bin/python_old
PYPY:http://pkgs.org/search/?keyword=pypy
wget http://dl.fedoraproject.org/pub/epel/6/x86_64/pypy-libs-2.0.2-1.el6.x86_64.rpm wget http://dl.fedoraproject.org/pub/epel/6/x86_64/pypy-2.0.2-1.el6.x86_64.rpm wget http://dl.fedoraproject.org/pub/epel/6/x86_64/pypy-devel-2.0.2-1.el6.x86_64.rpm
注意安装顺序 先安装libs 再安装pypy 最后安装devel
经测试 pypy的效率要比cpython高大约三到四倍
实现Python的交互模式下tab自动补全和vim下python tab自动补全:
下面是.pythonrc.py的内容
try: import readline except ImportError: print("Module readline not available.") else: import rlcompleter readline.parse_and_bind("tab: complete")
vim ~/.bashrc export PYTHONSTARTUP=~/.pythonrc.py #加入此行
vim下:
wget unzip -q master mv pydiction-master pydiction mkdir -p ~/.vim/tools/pydiction cp -r pydiction/after ~/.vim cp pydiction/complete-dict ~/.vim/tools/pydiction
