如果"pip install"有效，为什么要使用"sudo pip install"? (与HelloAnalytics.py有关的问题) [英] Why 'sudo pip install' if 'pip install' works? (Issues with HelloAnalytics.py)

问题描述

Google提供了一个示例HelloAnalytics.py，以演示 google-api- python-client .

Google provides a sample HelloAnalytics.py to demonstrate the use of google-api-python-client.

在标题"2.下面.客户库" 他们写道:

使用pip，这是用于安装Python软件包的推荐工具:

Use pip, the recommended tool for installing Python packages:

sudo pip install --upgrade google-api-python-client

我想知道为什么在简单的pip(没有sudo)似乎可以完美工作(在Mac上)的情况下，为什么应该使用sudo:

I wonder why I should use sudo while a simple pip (without sudo) seems to work perfectly (on my Mac):

该样品只是过时了吗? (尽管 Python 2.7似乎使用了print，但没有()已被Google-api-python-client 弃用，其中混淆了其他人已经.)

Is that sample simply outdated? (They use print without () though Python 2.7 seems to be deprecated for google-api-python-client which confused others already.)

我解决了这个问题，但仍然得到了ModuleNotFoundError: No module named 'oauth2client'.我对丢失的sudo不是造成这种情况的原因吗?

I fixed that and still get an ModuleNotFoundError: No module named 'oauth2client'. Am I right that the missing sudo is not the cause for that?

好吧，他们没有解释VIEW_ID是什么，以及在哪里得到的.

Well, and they do not explain what a VIEW_ID is and where to get this.

推荐答案

它对您没有sudo起作用，因为您似乎在用户具有写许可权的位置安装了python.

It works without sudo for you because you seem to have python installed in a location where your user has write permissions.

Requirement already satisfied: setuptools>=34.0.0 in ./venv/lib/python3.7/site-packages (from google-api-core<2dev,>=1.18.0->google-api-python-client) (41.2.0)

这一切都取决于安装python的方式和位置. Mac OS发行版python安装在root拥有的/Library/中.因此，如果要安装新软件包，则需要使用sudo.

It all depends on how and where you install python. The mac os distro python is installed in /Library/ which is owned by root. So if you want to install a new package, you will need to use sudo.
