一、安裝（傻瓜式）

1、mkdir /usr/local/python3

2、cd /usr/local/python3

3、wget https://www.python.org/ftp/python/3.6.5/Python-3.6.5.tgz?

4、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 ?# 這一步是環(huán)境準備，報錯可略過，可在最開始執(zhí)行

5、tar zxvf Python-3.6.5.tgz? ? # 解壓到當前文件夾即可

6、./configure --prefix=/etc/python/python3.6 ?

7、make && make install

8、ln -s /etc/python/python3.6/bin/python3.6 /usr/bin/python3? ?# 創(chuàng)建python3環(huán)境變量

9、ln -s /etc/python/python3.6/bin/pip3.6 /usr/bin/pip3? ? # 創(chuàng)建pip3環(huán)境便令

#檢查安裝是否成功

python3 -V
pip3 -V

pip3 install --upgrade pip setuptools wheel #pip3升級

二、安裝過程中遇到問題解決

1、python3.6: error while loading shared libraries: libpython3.6m.so.1.0: cannot open shared object file: No such file or directory
原因：因為python運行時沒有加載到libpython3.6m.so.1.0 這個庫文件 ? ? 將其復制到響應目錄OK
解決方法:

            
              #進入解壓后的編譯目錄，然后拷貝制定文件即可
cd /root/test/Python-3.6.0 ? ? 
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/
            
          

2、pip install 失敗 Can’t connect to HTTPS URL because the SSL module is not available
解決方法：yum install openssl-devel -y
