ubuntu18.04安装Python3.7

回答: 在Ubuntu 18.04系统中安装Python 3.7可以按照以下步骤进行操作。首先，需要执行系统升级来确保系统是最新的版本。可以使用以下命令执行升级:

sudo apt update
sudo apt upgrade -y

接下来需要安装编译Python源程序所需的包。可以使用以下命令安装这些包:

sudo apt install build-essential -y
sudo apt install libncurses5-dev libgdbm-dev libnss3-dev libssl-dev libreadline-dev libffi-dev -y
sudo apt-get install zlib1g-dev

然后，需要下载Python 3.7的源程序压缩包。可以使用wget命令下载:

wget https://www.python.org/ftp/python/3.7.1/Python-3.7.1.tgz

接着，需要解压缩下载的压缩包。可以使用以下命令进行解压缩:

tar -xzvf Python-3.7.1.tgz

然后进入解压缩后的目录，并进行配置:

cd Python-3.7.1
./configure --enable-optimizations

配置完成后，可以使用make命令编译并安装Python 3.7:

make
sudo make install

最后，可以将python3指向Python 3.7版本。可以使用以下命令进行设置:

sudo update-alternatives --install /usr/bin/python3 python3 /usr/local/bin/python3.7 1

这样，Python 3.7就安装完成了，并且python3命令将指向Python 3.7版本。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
