我是基于 Linux 的操作系统的新手（对 Snap7 也很陌生）。尝试按照http://python-snap7.readthedocs.io/en/latest/installation.html的说明在 Ubuntu 机器上安装 Snap7 库。但是我在第 3 步中遇到以下错误

E: Unable to locate package libsnap71
E: Unable to locate package libsnap7-dev

我不确定如何手动安装它，我不确定如何解决这个安装问题，所以任何建议都很棒:)

以下是已经运行“添加存储库”命令后的日志副本：

您在链接到的页面上错过了这部分：

If you are using Ubuntu you can use the Ubuntu packages from our launchpad PPA.
To install:

$ sudo add-apt-repository ppa:gijzelaar/snap7
$ sudo apt-get update
$ sudo apt-get install libsnap71 libsnap7-dev

按顺序执行所有三个命令，你应该没问题。但是，由于该软件比您的系统旧，您需要编辑在/etc/apt/sources.d第一步之后创建的文件并替换xenial（甚至yaketty）为trusty. ppa 仅具有旧版本的构建。

现在效果很好，请在此处使用说明

 $ sudo add-apt-repository ppa:gijzelaar/snap7
 $ sudo apt-get update
 $ sudo apt-get install libsnap7-dev libsnap7-1
