0.配置依赖环境，如果不进行这步可能会出现一些问题中间可能有多余空格，去除下再运行，一般都能安装成功，如果不能可以先更新下sudo apt-get updatesudo apt-get install zlib1g-dev libbz2-dev libssl-dev libncurses5-dev libsqlite3-dev libreadline-dev tk-dev libgdbm-dev libdb-dev libpcap-dev xz-utils libexpat1-dev liblzma-dev libffi-dev libc6-dev1.直接去官网下载你想的版本2.解压下载的包，在这之前你可以先mv你的包到指定位置解压jianjiacheng@J-computer:$ tar zxvf Python-3.7.13.进入解压目录jianjiacheng@J-computer:$ cd Python-3.7.1/4.建立安装的目录sudo mkdir -p /usr/local/python35.编译安装执行这步是后面最好加上 –enable-optimizations 会自动安装pip3及优化配置# ./configure –prefix=/usr/local/python3 –enable-optimizations# make# sudo make install6.删除软链接先执行查看版本，如果有则证明软链接已存在，需要先删去以前的再重新建立//这里表明我已有python3的软链接而没有pip3的软链接所以需要删除python3的软链接重新建立jianjiacheng@J-computer:/Python-3.7.1$ python3 -VPython 3.5.2jianjiacheng@J-computer:$ pip3 -Vbash: /usr/lib/command-not-found: /usr/bin/python3: bad interpreter: No such file or directoryrm -rf /usr/bin/python3rm -rf /usr/bin/pip37.建立新的指向python3.7的软链接#添加python3的软链接ln -s /usr/local/python3/bin/python3.7 /usr/bin/python3#添加 pip3 的软链接ln -s /usr/local/python3/bin/pip3.7 /usr/bin/pip38.检测版本jianjiacheng@J-computer:$ python3 -VPython 3.7.1jianjiacheng@J-computer:$ pip3 -Vpip 10.0.1 from /usr/local/python3/lib/python3.7/site-packages/pip (python 3.7)
