如何在标准的python环境中安装软件包， 即/usr/local/lib/python2.7/dist-

packages使用pip新的软件包并使所有用户可以使用该新软件包，而无需使用virtualenv？

通过使用以下内容，该软件包仅以root权限安装：

$ sudo pip install loremipsum
Downloading/unpacking loremipsum
  Downloading loremipsum-1.0.5.tar.gz
  Running setup.py (path:/tmp/pip_build_root/loremipsum/setup.py) 
  egg_info for package loremipsum
Installing collected packages: loremipsum
  Running setup.py install for loremipsum
Successfully installed loremipsum
Cleaning up...

证明：

$ python -c 'import loremipsum'
Traceback (most recent call last):
  File "<string>", line 1, in <module>
ImportError: No module named loremipsum
$ sudo python -c 'import loremipsum'
$ pip install loremipsum
Requirement already satisfied (use --upgrade to upgrade): loremipsum in 
/usr/local/lib/python2.7/dist-packages
Cleaning up...

                ||----w |
                ||     ||

请不要建议我apt-get install python-...改用。我想知道我的错误以及如何正确使用点子。

$ python --version
Python 2.7.6
$ pip --version
pip 1.5.4 from /usr/lib/python2.7/dist-packages (python 2.7)
$ uname -a
Linux _ 3.19.0-32-generic #37~14.04.1-Ubuntu SMP _ x86_64 GNU/Linux

我猜问题是因为pip不允许小组和所有人阅读已安装的内容：

$ sudo pip uninstall loremipsum
Uninstalling loremipsum:
  /usr/local/lib/python2.7/dist-packages/loremipsum-1.0.5.egg-info
  /usr/local/lib/python2.7/dist-packages/loremipsum/__init__.py
  /usr/local/lib/python2.7/dist-packages/loremipsum/__init__.pyc
  /usr/local/lib/python2.7/dist-packages/loremipsum/default/dictionary.txt
  /usr/local/lib/python2.7/dist-packages/loremipsum/default/sample.txt
  /usr/local/lib/python2.7/dist-packages/loremipsum/generator.py
  /usr/local/lib/python2.7/dist-packages/loremipsum/generator.pyc
Proceed (y/n)? y

回答：

你可能有一个错误的umask设定所讨论这里

从您的上一次编辑，我想您umask已设置为027。试着做

sudo pip uninstall loremipsum
umask 022
sudo pip install loremipsum
