1.本机centos6.6安装python3的方式：
python3.6.5的源码编译安装

# 准备编译环境
yum groupinstall 'Development Tools'
yum install zlib-devel bzip2-devel  openssl-devel ncurses-devel
# 创建安装目录
mkdir /usr/local/python3
# 解压
tar -xvJf Python-3.6.5.tar.xz
# 编译安装
cd Python-3.6.5
./configure --prefix=/usr/local/python3 --enable-optimizations
make
make install

# 是以优化的方式安装python3
--enable-optimizations

2.pyinstaller包的安装及异常处理

# 安装pyinstaller包
pip install pyinstaller

pyinstaller打包的demo示例:

# 创建目录
mkdir demo
# 进入目录
cd demo
# 创建demo
vi demo.py
# 写入内容，保存退出
name = input("请输入您的姓名：")
print(name)

打包

# 在demo目录下执行 打包为一个可执行文件
pyinstaller -F demo.py

This would mean your Python installation doesn't come with proper library files.
This usually happens by missing development package, or unsuitable build parameters of Python installation.

* On Debian/Ubuntu, you would need to install Python development packages
  * apt-get install python3-dev
  * apt-get install python-dev
* If you're building Python by yourself, please rebuild your Python with `--enable-shared` (or, `--enable-framework` on Darwin)

异常问题：从异常代码中可以看出OSError: Python library not found，异常主要是自己安装Python过程中没有设置Python的库共享，pyinstaller打包过程依赖缺失。

解决方案：如下截图所示，需要重新对Python安装包进行编译安装

Python重新配置，编译安装

# 进入Python-3.6.5的目录 重新设置配置
./configure --prefix=/usr/local/python3 --enable-shared
# 编译安装
make
make install

在python3.6.5的目录下可以看到生成的库文件：

测试Python是否安装成功：

# 执行命令 进入交互环境
python3

可能会出现以下异常，需要复制共享库到相应的目录

python3: error while loading shared libraries: libpython3.6m.so.1.0: cannot open shared object file: No such file or directory

解决方案

# 查看python3动态链接库
ldd /usr/bin/python3
# 没有libpython3.6m.so.1.0则，进入Python-3.6.5 目录进行复制文件
cp libpython3.6m.so.1.0 /usr/local/lib64/
cp libpython3.6m.so.1.0 /usr/lib
cp libpython3.6m.so.1.0 /usr/lib64/

异常解决之后重新打包，如下图可以看出，成功加载python的库，exe文件也打包成功：

生成的新文件，进入dist目录，可以看到demo的可执行文件：
