Linux安装python3.6

AllenNLP requires Python 3.6.1 or later. and CUDA 9 only (or no GPU)

1. 安装依赖环境

# 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

1. 下载Python3

https://www.python.org/downloads/

# wget https://www.python.org/ftp/python/3.6.5/Python-3.6.5.tgz

3.安装python3

我个人习惯安装在/usr/local/python3（具体安装位置看个人喜好）

创建目录：

# mkdir -p /usr/local/python3

进入python3目录，解压下载好的Python-3.x.x.tgz包(具体包名因你下载的Python具体版本不不同⽽而不不同，如：我下载的是Python3.6.5.那我这里就是Python-3.6.5.tgz)

# tar -zxvf Python-3.6.5.tgz

4.进入解压后的目录，编译安装。

在安装python时 ./configure指定引入ssl, 否则使用pip３６ install xxx命令时报ssl缺失的错误

# cd Python-3.6.5
# ./configure --with-ssl --prefix=/usr/local/python3
# make && make install

5.建立python3的软链

# ln -s /usr/local/python3/bin/python3 /usr/bin/python36

6.并将/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
按ESC，输入:wq回车退出。

修改完记得执行行下面的命令，让上一步的修改生效：

# source ~/.bash_profile

检查Python3及pip3是否正常可用：

# python36 -V
Python 3.6.5
# pip36 -V
pip 9.0.1 from /usr/local/python3/lib/python3.6/site-packages (python 3.6)

7.不行的话在创建一下pip3的软链接

# ln -s /usr/local/python3/bin/pip3 /usr/bin/pip36

安装allennlp包

https://github.com/allenai/allennlp

1. Installing the library and dependencies is simple using pip.

# pip36 install allennlp

1. You can now test your installation with allennlp test-install .
