CentOS安裝Python3.7

vscode設置python3.7調試環境：http://www.javashuo.com/article/p-tvzhtwbx-bq.html

先下載一下壓縮包(FTP傳也同樣)：weget https://www.python.org/ftp/python/3.7.0/Python-3.7.0.tar.xz

目前最新：https://www.python.org/ftp/python/3.7.1/Python-3.7.1.tar.xz

解壓：tar -Jxvf Python-3.7.0.tar.xz

cd Python-3.7.0 設置一下配置文件，準備編譯安裝 ./configure prefix=/usr/local/python3

對於老手，缺啥安裝啥，新手建議安裝以下安裝包（這樣你不會出錯）

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 kernel-devel libffi-devel

編譯安裝：make && make install（yum安裝沒有apt安裝方便）

設置軟連接：ln -s /usr/local/python3/bin/python3 /usr/bin/python3
