Linux下Python3安装时出现的报错

在将python3安装包下载到目录中，解压后进入到python文件目录下，执行配置安装路径

./configure prefix=/usr/local/python3

出现报错：

See `config.log' for more details

明显编译环境出错，下载安装GCC

yum install gcc

成功后再进行配置安装路径。

make&&make install编译后进行软链接可能忘记已经添加过其它出现报错

ln: failed to create symbolic link ‘python3’: File exists

没关系，删了再链接就可以

rm -rf /usr/bin/python3
