centos 安裝python3.7

 先安裝依賴包：

yum -y install bzip2 bzip2-devel ncurses openssl openssl-devel openssl-static xz lzma xz-devel sqlite sqlite-devel gdbm gdbm-devel tk tk-devel libffi-devel

 

wget https://www.python.org/ftp/python/3.7.1/Python-3.7.1.tar.xz
## 安裝報錯找不到 _ctype zlib 等模塊
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
yum -y install gcc kernel-devel kenel-headers make bzip2
yum -y install readline-devel libffi-devel
yum -y install e2fsprogs-devel uuid-devel libuuid-devel
# 解壓文件
tar -xvf Python-3.7.1.tar.xz
# 進入到該文件夾
cd Python-3.7.1/
# --prefix 欲安裝目錄
./configure --prefix=/usr/local/python3.7 --enable-optimizations
# 編譯安裝,make時間比較長，大概須要15分鐘
make
make install
rm -f /usr/bin/python3
ln -s /usr/local/python3.7/bin/python3.7 /usr/bin/python3
ln -s /usr/local/python3.7/bin/pip3 /usr/bin/pip3

# 還須要從新編譯安裝纔有效
