我已经开始使用我的Mac来安装Python软件包,就像我在工作时使用Windows PC一样; 但是在我的Mac上,我在写入日志文件或站点包时遇到了频繁的权限被拒绝错误.

因此我考虑过运行pip install <package>,sudo但考虑到我只是希望将其安装在我当前的用户帐户下,这是一个安全/可接受的sudo使用方法吗？

来自日志文件I/O错误的示例回溯:

Command /usr/bin/python -c "import setuptools;__file__='/Users/markwalker/build/pycrypto/setup.py';exec(compile(open(__file__).read().replace('\r\n', '\n'), __file__, 'exec'))" install --single-version-externally-managed --record /var/folders/tq/hy1fz_4j27v6rstzzw4vymnr0000gp/T/pip-k6f2FU-record/install-record.txt failed with error code 1 in /Users/markwalker/build/pycrypto

偶尔我碰上评论或回应表示国家重点跑跑pip下sudo是"错误"或"坏",但也有例(其中我有一堆的设置工具的方式),其中它要么是简单得多,或者甚至是必要的以这种方式运行.

什么是与运行相关的风险pip下sudo？

请注意,这与此问题的问题不同,尽管标题不提供有关风险的信息.这也不是关于如何避免使用的问题sudo,而是关于人们想要的具体原因.

我在这里关注Flask教程:

http://blog.miguelgrinberg.com/post/the-flask-mega-tutorial-part-i-hello-world

我到达了尝试./run.py的地步,我得到:

Traceback (most recent call last):
  File "./run.py", line 3, in <module>
    from app import app
  File "/Users/benjaminclayman/Desktop/microblog/app/__init__.py", line 1, in <module>
    from flask import Flask
ImportError: No module named flask

这看起来类似于:

ImportError:没有名为flask的模块

但他们的解决方案没有帮助.作为参考,我也有这一个用户提到可能会导致问题的文件夹命名的烧瓶中.

在服务器上运行flask项目时，出现以下错误：

Traceback (most recent call last):
  File "File.py", line 1, in <module>
    from flask import Flask, request
ImportError: No module named 'flask'

但是我已经安装了烧瓶！

$sudo pip install flask

这真让我抓狂。我尝试了其他SO答案提出的建议，包括使用venv，但是它们都会产生相同的错误。有人有建议吗？
