1. 安装依赖包

#yum install readline-devel gcc make patch gdbm-devel openssl-devel sqlite-devel readline-devel zlib-devel bzip2-devel ##必须安装否则会出现python3编译器中不能使用退格键和方向键

2. 下载安装包

wget https://www.python.org/ftp/python/3.6.1/Python-3.6.1.tgz

3. 解压安装包

tar zvxf Python-3.6.1.tgz

4. 创建安装目录

mkdir /usr/local/python3

5. 安装命令

./configure --enable-shared  --with-openssl=/usr/local/openssl
或者
./configure --with-openssl=/usr/include/openssl --prefix=/usr/local/python36 --enable-optimizations
make
make altinstall

6. 添加软链接

ln -s /usr/local/python3/bin/pip3.8 /usr/bin/pip
ln -s /usr/local/python3/bin/python3.8 /usr/bin/python

7. 临时禁用 SSL 验证

pip install --trusted-host pypi.org --trusted-host files.pythonhosted.org package_name

8. 使用 HTTP 镜像源

pip install -i <http://mirrors.aliyun.com/pypi/simple/> package_name

9. 创建虚拟环境

python -m venv venv

10. 虚拟环境使用

source activate

11. 错误处理

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

# 查看动态链接库
ldd /usr/local/python36/bin/python3
# 复制文件
cp libpython3.6m.so.1.0 /usr/lib64/

pip is configured with locations that require TLS/SSL, however the ssl module in Python is not available ·pip install pyinstaller -i http://pypi.douban.com/simple --trusted-host pypi.douban.com`
pip 限制 https

# 创建文件
vi ~/.pip/pip.conf
# 复制以下内容
[global]
index-url = http://mirrors.aliyun.com/pypi/simple/

[install]
trusted-host = mirrors.aliyun.com

11.1. pip 安装时提示 ssl 错误，可以临时跳过

pip install --trusted-host mirrors.aliyun.com -i http://mirrors.aliyun.com/pypi/simple/ package_name

11.2. 安装缺少 ssl 模块

Modules/Setup 去掉注释这五行

./configure --with-ssl --prefix=/usr/local/python3.8
make && make install
