python - 在 Linux (Ubuntu 17) 上导入 python-pptx 时出现问题

Question

我正在尝试在 python 程序中导入 python pptx 库。我之前使用 pip 安装它，它给了我以下输出:

所以这似乎是成功的。但是当我尝试使用以下代码导入模块时:

try:
    from pptx import Presentation
except Exception as e:
    print(e)

它说没有名为“pptx”的模块。它一定与 Linux 有关，因为相同的代码在 Windows 上工作得很好，而且模块似乎安装正确。我正在使用 Python 3.5.3。

使用 pip install，您将为 Python2 而不是 Python3 安装它。为确保为 Python3 安装它，从解释器调用 pip，如下所示:

python3 -m pip install <package>
