CENTOS7 Python3.7.1 安装 pyzmq（centos7安装python3.6）

直接安装出现错误，缺少库文件

    gcc -pthread build/temp.linux-aarch64-3.7/scratch/tmp/timer_createv3ufssd_.o -o build/temp.linux-aarch64-3.7/scratch/a.out
    build/temp.linux-aarch64-3.7/scratch/tmp/timer_createv3ufssd_.o: In function `main'':

    collect2: error: ld returned 1 exit status

     #include "zmq.h"
                     ^
    compilation terminated.
    
    error: command ''gcc'' failed with exit status 1
    
    Failed with default libzmq, trying again with /usr/local
    {''libraries'': [''zmq''], ''include_dirs'': [''/usr/local/include''], ''library_dirs'': [''/usr/local/lib''], ''runtime_library_dirs'': [''/usr/local/lib''], ''extra_link_args'': []}

解决

sudo yum -y install zeromq-devel zeromq
sudo yum -y install czmq-devel czmq

pip3.7 install pyzmq

() centos7 安装 python36

 centos7 默认安装 python2.7

1. 先安装 python36 和对应 pip

yum install python-pip #安装python2的pip
yum install python36
yum install python36-pip

2. 修改软链接

（1）软链接由 python2 变成 python3

ln -snf python3 python

（2）pip 默认成 python3 的

mv pip pip.bak
ln -snf pip3 pip

3. 修改 #！文件

yum 和 urlgrabber-ext-down 需要依赖 Python2

vim /usr/bin/yum
vim /usr/libexec/urlgrabber-ext-down

都改成 #! /usr/bin/python2.7

手动安装的软件一般在此目录下

/usr/local

centos7 - 安装 python3.7

说明

全部操作都在 root 用户下执行

1. 安装编译相关工具

yum -y groupinstall "Development tools"
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
yum install libffi-devel -y

2. 下载安装包解压

cd #回到用户目录
wget https://www.python.org/ftp/python/3.7.0/Python-3.7.0.tar.xz
tar -xvJf  Python-3.7.0.tar.xz

3. 编译安装

mkdir /usr/local/python3 #创建编译安装目录
cd Python-3.7.0
./configure --prefix=/usr/local/python3
make && make install

4. 创建软连接

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

5. 验证是否成功

python3 -V
pip3 -V
