Linux下安裝python3.6
1. 安裝依賴環(huán)境
yum -y install zlib-devel bzip2-devel openssl-devel ncurses-devel sqlite-devel readline-devel tk-devel gdbm-devel db4-devel libpcap-devel xz-devel
2.下載Python3
https://www.python.org/downloads/
wget https://www.python.org/ftp/python/3.6.1/Python-3.6.1.tgz
3.安裝python3
我個(gè)人習(xí)慣安裝在/usr/local/python3（具體安裝位置看個(gè)人喜好）
創(chuàng)建目錄：
mkdir -p /usr/local/python3
解壓下載好的Python-3.x.x.tgz包(具體包名因你下載的Python具體版本不不同?而不不同，如：我下載的是Python3.6.1.那我這里就是Python-3.6.1.tgz)
tar -zxvf Python-3.6.1.tgz
4.進(jìn)入解壓后的目錄，編譯安裝。
cd Python-3.6.1
./configure --prefix=/usr/local/python3
make && make install
5.建立python3的軟鏈
ln -s /usr/local/python3/bin/python3 /usr/bin/python3
6.并將/usr/local/python3/bin加入PATH
vim ~/.bash_profile
.bash_profile
# Get the aliases and functions
if [ -f ~/.bashrc ]; then
. ~/.bashrc
fi
# User specific environment and startup programs
PATH=$PATH:$HOME/bin:/usr/local/python3/bin
export PATH
source ~/.bash_profile
檢查Python3及pip3是否正?？捎茫?/p>
# python3 -V
Python 3.6.1
# pip3 -V
pip 9.0.1 from /usr/local/python3/lib/python3.6/site-packages (python 3.6)
7.不行的話在創(chuàng)建一下pip3的軟鏈接(我也不清楚這一步有什么用)
ln -s /usr/local/python3/bin/pip3 /usr/bin/pip3
安裝pip前需要前置安裝setuptools
命令如下：
wget --no-check-certificate https://pypi.python.org/packages/source/p/pip/pip-8.0.2.tar.gz#md5=3a73c4188f8dbad6a1e6f6d44d117eeb
tar -zxvf pip-8.0.2.tar.gz
cd pip-8.0.2
python3 setup.py build
python3 setup.py install
如果前面沒(méi)布置好環(huán)境的話，就要苦逼一下了：
報(bào)錯(cuò)： RuntimeError: Compression requires the (missing) zlib module
我們需要在linux中安裝zlib-devel包，進(jìn)行支持。
yum install zlib-devel
需要對(duì)python3.5進(jìn)行重新編譯安裝。
cd python3.6.1
make && make install
又是漫長(zhǎng)的編譯安裝過(guò)程。
重新安裝setuptools
python3 setup.py build
python3 setup.py install
2、安裝pip
命令如下：
wget --no-check-certificate https://pypi.python.org/packages/source/p/pip/pip-8.0.2.tar.gz#md5=3a73c4188f8dbad6a1e6f6d44d117eeb
tar -zxvf pip-8.0.2.tar.gz
cd pip-8.0.2
python3 setup.py build
python3 setup.py install
