我正在一个新的Ubuntu 14安装上设置saleor，当我运行以下命令时：
pip install-r requirements.txt
我有个例外。我对Linux没有那么了解，我遇到了一个错误，我不知道如何解决。我认为这是在抱怨requirements.txt文件中特定行的格式，但我不知道为什么。
我得到的例外是：
Exception:

先决条件在准备运行Saleor之前，您需要计算机上安装的其他软件。
Python 3 Saleor需要Python 3.4或更高版本。兼容版本预装在大多数当前的Linux系统中。如果不是有关如何安装的说明，请参阅您的发行版Python 3.6或3.7。(https://saleor.readthedocs.io/en/latest/gettingstarted/installation-linux.html)
仅供参考：Ubuntu的最新LTS版本是18.04。你系统中的那个已经4岁多了。
如上所述，ubuntu 14非常旧，因为您使用的是更新版本的saleor。存在兼容性问题。升级到ubuntu 18或ateast 16以避免这些错误
