Install Python 3.7 on Raspberry Pi

步驟一:更新

sudo apt-get update

步驟二:安裝對應的LIB

sudo apt-get install -y build-essential tk-dev libncurses5-dev 
libncursesw5-dev libreadline6-dev libdb5.3-dev libgdbm-dev 
libsqlite3-dev libssl-dev libbz2-dev libexpat1-dev 
liblzma-dev zlib1g-dev libffi-dev

步驟三:下載Python

wget https://www.python.org/ftp/python/3.7.0/Python-3.7.0.tar.xz

步驟四:解壓縮並且編譯

tar xf Python-3.7.0.tar.xz
cd Python-3.7.0
./configure --prefix=/usr/local/opt/python-3.7.0
make -j 4

步驟五:安裝

sudo make altinstall

步驟六:建立連結

Make Python 3.7 the default version, make aliases
sudo ln -s /usr/local/opt/python-3.7.0/bin/pydoc3.7 /usr/bin/pydoc3.7
sudo ln -s /usr/local/opt/python-3.7.0/bin/python3.7 /usr/bin/python3.7
sudo ln -s /usr/local/opt/python-3.7.0/bin/python3.7m /usr/bin/python3.7m
sudo ln -s /usr/local/opt/python-3.7.0/bin/pyvenv-3.7 /usr/bin/pyvenv-3.7
sudo ln -s /usr/local/opt/python-3.7.0/bin/pip3.7 /usr/bin/pip3.7
alias python='/usr/bin/python3.7'
alias python3='/usr/bin/python3.7'

步驟七:移除因為安裝所存留的暫存檔

cd ..
sudo rm -r Python-3.7.0
rm Python-3.7.0.tar.xz
. ~/.bashrc

步驟八:確定是否成功

python -V
