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

Question

我在我的PC上使用python-docx和docx ，但是当我将项目克隆到Google Cloud时，出现了问题。 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的问题：

更新

将这些三维派对库安装到项目lib文件夹中已经受益，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>

ImportError: No module named lxml.etree

顺便说一句，这是一个正确的方式，因为：

您可以在Coogle Cloud Shell虚拟机实例上安装其他软件包，但在实例终止后安装将不会保留，除非您在$ HOME目录（ 源 ）中安装该软件。

Answer 1

使用Google Cloud Shell只能在$ HOME目录中安装持久数据 。 达到非活动时间限制为60分钟，VM实例将被终止。 之后访问它，它将从新VM实例上的映像进行配置。

但是，Google Cloud Shell 在$ HOME目录中有5GB持久性存储空间 ，它不会过期，但可能会被回收。 用户在回收过程之前收到电子邮
