Question

我正在尝试执行 pygam （来自pygam导入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和pip都安装了pip3的问题。

当我尝试使用 pip 重新安装它时的结果：

DEPRECATION: Python 2.7 will reach the end of its life on January 1st, 2020. Please upgrade your Python as Python 2.7 won't be maintained after that date. A future version of pip will drop support for Python 2.7. More details about Python 2 support in pip, can be found at https://pip.pypa.io/en/latest/development/release-process/#python-2-support

，这是我尝试使用 pip3 重新安装它们的结果：

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.

我发现这是正常现象，因为我只是安装了它，但我不明白为什么他们看不到 pygam

Answer 1

确保您具有正确版本的python和pip。尝试使用您用于运行脚本的python（具有正确的版本）再次安装它。例如，您要使用[yhon3.5使用以下命令来运行它：

python3.5 -m pip install pygam

我假设上述命令中的python3.5调用了Python 3.5，在我的系统上，我有python3调用了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正在运行的pip版本及其所安装的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)

如果系统上安装了多个版本的python，则以上内容很方便。让我们知道是否有帮助。

确保您没有使用虚拟环境，必须安装 pygame ，只需运行以下命令：

pip install pygame

安装它，然后重试。有关更多信息，请访问https://pypi.org/project/pygame/
