CentOS7安装Python3.5

 

2. 安装Python的依赖包

1 2	yum -y groupinstall "Development tools" yum -y install openssl-devel sqlite-devel bzip2-devel ncurses-devel gdbm-devel readline-devel tcl-devel tk-devel xz-devel zlib-devel db4-devel libpcap-devel

2. 下载Python3.5的源码包并编译

1 2 3 4 5 6 7 8

cd /usr/local/src wget https://www.python.org/ftp/python/3.5.1/Python-3.5.1.tgz tar -zxf /usr/local/src/Python-3.5.1.tgz && cd Python-3.5.1 ./configure --prefix=/opt/python3.5 --enable-shared make && make install ln -s /opt/python3.5/bin/python3 /usr/bin/python3 echo "/opt/python3.5/lib" > /etc/ld.so.conf.d/python3.5.conf ldconfig

检测python3.5是否安装成功

1	python3 --version

3. 升级pip

因为python3.5自带pip，setuptools

1 2	/opt/python3.5/bin/pip3 install --upgrade pip ln -s /opt/python3.5/bin/pip /usr/bin/pip3

3. 升级setuptools

1 2	wget https://bootstrap.pypa.io/ez_setup.py -O - | python3 ln -s /opt/python3.5/bin/easy_install /usr/bin/easy_install
