安装python 3模块问题

Question

我在OSUbuntu19.04上安装Python3.7.3和Python2.7.16的模块有问题

该模块仅用于Python>=3.5。

研究并没有把我引向太多，或者我找错了地方，或者我误解了错误的全部信息。

我发现最好的方法是避免移除Python 2，以免破坏其他需要它的程序，而且我也没有删除Python 2。如果能提供任何帮助，我们将不胜感激。有关更多信息，请参见下面：

电流路径

/usr/bin/python

Pip命令我尝试使用

pip install python-chess

误差

Collecting python-chess

        """)
    ImportError: You are installing python-chess on Python 2.

    Python 2 support has been dropped. Consider upgrading to Python 3, or using
    the 0.23.x branch, which will be maintained until the end of 2018.

类似于python (python2.7)和python3 (python3.x)，有pip (python2.7)和pip3 (python3.x)。

若要安装python3模块，请使用pip3。
