一 下載
wget https://www.python.org/ftp/python/3.7.1/Python-3.7.1rc2.tgz

二 解壓
tar zxvf Python-3.7.1rc2.tgz
cd Python-3.7.1rc2

三 編譯

./configure
make
make install

先找的python3.7解釋器位置，一般是
/usr/local/bin/python3.7

四 刪除原來的軟連接

rm -rf /usr/bin/python3
rm -rf /usr/bin/pip3

五 添加python3的軟鏈接

ln -s /usr/local/bin/python3.7 /usr/bin/python3
#添加 pip3 的軟鏈接
ln -s /usr/local/bin/pip3.7 /usr/bin/pip3

六：問題備忘

?問題一：?報錯ModuleNotFoundError: No module named '_ctypes'

? 解決方法：

            sudo apt-
            
              get update
sudo apt
            
            -
            
              get upgrade
sudo apt
            
            -get dist-
            
              upgrade
sudo apt
            
            -get install build-essential python-dev python-setuptools python-pip python-
            
              smbus
sudo apt
            
            -get install build-essential libncursesw5-dev libgdbm-dev libc6-
            
              dev
sudo apt
            
            -get install zlib1g-dev libsqlite3-dev tk-
            
              dev
sudo apt
            
            -get install libssl-
            
              dev openssl
sudo apt
            
            -get install libffi-dev
          

?問題二：?zipimport.ZipImportError: can’t decompress data; zlib not available?

? ?解決方法：sudo apt-get install zlib*

問題三：?出現locations that require TLS/SSL異常處理方法

??sudo apt-get install gcc libffi-devel zlib* openssl-devel

?然后重新編輯和安裝python7即可
