在Debian 9上安装Python 3并设置编程环境

Debian Linux预装了Python 3和Python 2。为了确保我们的版本是最新的更新，让我们使用apt命令更新和升级系统使其能够与Advanced Packaging Tool协同工作：

sudo apt update
sudo apt -y upgrade

该-y标志将确认我们同意所有要安装的项目。

一旦完成该过程，我们可以通过键入以下内容来检查系统中安装的Python 3的版本：

python3 -V

您将在终端窗口中收到输出，告知您版本号。虽然这个数字可能会有所不同，但输出结果与此类似：

Python 3.5.3

要管理Python的软件包，让我们安装pip，这个工具将安装和管理我们可能想要在我们的开发项目中使用的编程包。

sudo apt install -y python3-pip

还有一些软件包和开发工具可以安装，以确保我们为编程环境提供强大的设置：

sudo apt install build-essential libssl-dev libffi-dev python3-dev

zlib库

sudo apt-get install zlib1g-dev

OpenSSL库

sudo apt-get install openssl libssl-dev

Ubuntu出现无法定位软件包，更换源

解决办法很简单，更换另一个源就行了。一般建议是使用国内的源。

1.在修改source.list前，最好先备份一份
执行备份命令

sudo cp /etc/apt/sources.list /etc/apt/sources.list.old

2.执行命令打开sources.list文件：

sudo vim /etc/apt/sources.list

将下边的阿里源复制进去，然后点击保存关闭。
