Ubuntu更新python3.5到python3.7

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
