如何在 CentOS 6.5 AMD64 上安装 Python 3.2.2 并保留其原始 Python 安装(2.6.6)?
答案1
安装 Python 3.2.2(CentOS 6.5 AMD64):
为了编译 Python,你必须先安装开发工具和一些额外的库。这些额外的库并不是编译 Python 所必需的,但如果没有它们,你的新 Python 解释器将毫无用处
sudo yum groupinstall "Development tools"
sudo yum install zlib-devel bzip2-devel openssl-devel ncurses-devel sqlite-devel readline-devel tk-devel gdbm-devel db4-devel libpcap-devel xz-devel
以下是下载、编译和安装 Python 的命令
cd /usr/local/src
sudo wget http://python.org/ftp/python/3.2.2/Python-3.2.2.tar.xz --no-check-certificate
sudo tar xf Python-3.2.2.tar.xz
cd Python-3.2.2
sudo ./configure --prefix=/usr/local --enable-shared LDFLAGS="-Wl,-rpath /usr/local/lib"
sudo make && sudo make altinstall
运行上述命令后,新安装的 Python 解释器将作为 /usr/local/bin/python3.2 使用
/usr/local/bin/python3.2
下载并安装 Setuptools + pip
cd /usr/local/src
sudo wget https://bitbucket.org/pypa/setuptools/raw/bootstrap/ez_setup.py
sudo /usr/local/bin/python3.2 ez_setup.py
sudo /usr/local/bin/easy_install-3.2 pip
创建独立的 Python 3.2 环境
sudo /usr/local/bin/pip3.2 install virtualenv
sudo /usr/local/bin/virtualenv /usr/local/virtenv3.2
cd /usr/local/virtenv3.2
source bin/activate
python --version # (To check version)
