1.1 首先安装gcc编译器gcc有些系统版本已经默认安装通过 gcc --version 查看没安装的先安装gcc
yum -y install gcc glibc make1.2 安装其它依赖包注不要缺少否则有可能安装python出错python3.7.0以下的版本可不装 libffi-devel
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 libffi-devel1.3 下载python源码包此处我选择安装 python:3.7.4
wget https://www.python.org/ftp/python/3.7.4/Python-3.7.4.tgz1.4 解压源码包
tar zxvf Python-3.7.4.tgz 1.5 编译python
# 新建一个目录用来存放并安装python3 程序
mkdir /opt/app/python3.7.4# 切换到解压包之后的Python3.7.4目录
cd Python-3.7.4# ./configure 用来生成编译参数--prefix 用来指定安装目录此处填写刚刚创建的绝对路径/opt/app/python3.7.4
./configure --prefix/opt/app/python3.7.4# make 为生成二进制安装文件make install 用来进行执行安装。
make make install 当看到如下文时证明安装成功。 Looking in links: /tmp/tmpf2__yj7o

二、 安装模块
pip3.7 install requests更新 pip3.7 install --upgrade pippip3.7 install pymysql
pip3.7 install pillow
安装图形识别模块 pip3.7 install tesserocr 注此时会有报错 gcc -pthread -Wno-unused-result -Wsign-compare -DNDEBUG -g -fwrapv -O3 -Wall -fPIC -I/opt/app/python3.7.4/include/python3.7m -c tesserocr.cpp -o build/temp.linux-x86_64-3.7/tesserocr.ogcc: error trying to exec cc1plus: execvp: No such file or directoryerror: command gcc failed with exit status 1----------------------------------------

解决方法
yum -y install tesseract-devel
yum -y install gcc-c
再次安装无问题 pip3.7 install tesserocr
