我正在笔记本电脑上运行带有Linux的Debian9，并且我已经下载了python（python3.7）的新版本，并尝试在计算机上手动安装它，然后将其作为外部解释器添加到pycharm IDE中。 br /> 添加后，我尝试使用pip安装软件包，但出现以下问题：

ERROR: Exception:

在意识到这与我的/ usr / bin目录中的lsb_release脚本有关之后，我尝试在此文件中进行调查，问题出在哪里，并得到了以下信息（运行命令lsb_release -a之后）：>

      File "/usr/bin/lsb_release",line 64
    print("No LSB modules are available.",file=sys.stderr)
                                               ^
SyntaxError: invalid syntax

如何解决此问题？有没有办法重新安装lsb_release？

这就是我调用/usr/bin/python3或调用python时得到的：
