python - 如何在 Google Cloud Shell 上安装库 python-docx/docx？

Question

我在 PC 上使用 python-docx 和 docx，但是当我将项目克隆到 Google Cloud 时，问题出现了。docx 和 python-docx 都安装在那里:

igorsavinkin555@cloudshell:~/corrections-msword (coral-heuristic-5610)$ pip install docx --user
Requirement already satisfied: docx in /home/igorsavinkin555/.local/lib/python2.7/site-packages (0.2.4)
Requirement already satisfied: lxml in /home/igorsavinkin555/.local/lib/python2.7/site-packages (from docx) (4.2.4)
Requirement already satisfied: Pillow>=2.0 in /home/igorsavinkin555/.local/lib/python2.7/site-packages (from docx) (5.2.0)
igorsavinkin555@cloudshell:~/corrections-msword (coral-heuristic-215610)$ pip install python-docx --user
Requirement already satisfied: python-docx in /home/igorsavinkin555/.local/lib/python2.7/site-packages (0.8.7)
Requirement already satisfied: lxml>=2.3.2 in /home/igorsavinkin555/.local/lib/python2.7/site-packages (from python-docx) (4.2.4)
igorsavinkin555@cloudshell:~/corrections-msword (coral-heuristic-215610)$

docx.Document 问题:

igorsavinkin555@cloudshell:~/corrections-msword (coral-heuristic-215610)$ dev_appserver.py $PWD

    from docx.document import Document
ImportError: No module named docx.document  

更新

The installing of those 3-d party libraries into project lib文件夹受益，现在这些包在 project/lib 文件夹中。然而，现在 lxml 库中的错误:

  File "/home/igorsavinkin555/corrections-msword/main.py", line 2, in <module>
    from docx.document import Document
  File "/home/igorsavinkin555/corrections-msword/lib/docx/__init__.py", line 3, in <module>
    from docx.api import Document  # noqa
  File "/home/igorsavinkin555/corrections-msword/lib/docx/api.py", line 14, in <module>
    from docx.package import Package

", line 1095, in load_module
    raise ImportError('No module named %s' % fullname)
ImportError: No module named lxml.etree

顺便说一下，这是一个正确的方法，因为:

You can install additional software packages on the Coogle Cloud Shell virtual machine instance but the installation will not persist after the instance terminates unless you install the software in your $HOME directory (source).

Answer 1

使用 Google Cloud Shell 只能用于 install persistent data in the $HOME directory .达到 60 分钟的非事件时间限制，VM 实例将被终止。之后访问它，它将从新 VM 实例上的镜像进行配置。

但是，Google Cloud Shell 有 5GB persistent dis storage located in $HOME directory ，不会过期，但可以回收。用户在回收过程之前收到电子邮件。
