我正在尝试执行 pygam 的 python 脚本(from pygam import LogisticGAM, LinearGAM ).
当我尝试执行此脚本时出现此错误: ModuleNotFoundError: 没有名为“pygam”的模块
pygam同时安装了pip和pip3的问题。
这是我尝试使用 pip 重新安装它时的结果:

You are using pip version 8.1.1, however version 19.2.3 is available.
You should consider upgrading via the 'pip install --upgrade pip' command.
我发现这是正常的，因为我只是安装它，但我不明白为什么他们看不到pygam
请您参考如下方法:
确保您拥有正确版本的 python 和 pip。 尝试使用用于运行脚本的 python(正确版本)再次安装它。 例如，您想使用 [yhon3.5 使用以下命令运行它:
python3.5 -m pip install pygam
我假设 python3.5 在上面的命令中调用 Python 3.5，在我的系统上我有 python3 调用 Python 3.5
也尝试使用 sudo 安装
sudo pip install pygam
# OR
sudo pip3 install pygam
pip -V 命令将为您提供当前运行的 pip 版本和安装它的 python 版本。 示例:
pip -V
pip 9.0.1 from /usr/lib/python2.7/dist-packages (python 2.7)
pip3 -V
pip 9.0.1 from /usr/lib/python3/dist-packages (python 3.6)
如果在一个系统上安装了多个版本的 python，以上内容会派上用场。 如果有帮助，请告诉我们。
