本文主要介紹在Centos7系統上如果安裝編譯指的Python版本，本例安裝Python-3.6.1
首先，為系統安裝所需的依賴庫，可根據具體使用情況安裝，如：yum install -y gcc zlib zlib-devel openssl-devel bzip2-devel openssl-devel sqlite-devel ncurese-devel
下載下傳源碼包：wget https://www.python.org/ftp/python/3.6.1/Python-3.6.1.tar.xz
解壓安裝：# xz -d Python-3.6.1.tar.xz
# tar -xvf Python-3.6.1.tar
# cd Python-3.6.1/
# ./configure --prefix=/usr/local/python3 --enable-optimizations
# make && make install
建立指令軟連結：# ln -s /usr/local/python3/bin/python3.6 /usr/bin/python3
# ln -s /usr/local/python3/bin/pip3 /usr/bin/pip3
安裝相應模闆，根據需要安裝，如：pip3 install pymysql
pip3 install requests
pip3 install PyQuery
如果出現如下提示：You are using pip version 9.0.1, however version 18.0 is available.You should consider upgrading via the 'pip install --upgrade pip' command.
表可pip版本過低，可執行指令更新：# pip3 install --upgrade pip
