AWS ec2实例上的"sudo pip"时出错

Question

我试图在aws ec2实例上运行一个小的python代码(需要pytz和其他一些软件包).当我尝试安装pytz时,我遇到了一些错误:

[ec2-user@ip-172-31-28-178 ~]$ pip install pytz
Collecting pytz
  Using cached pytz-2016.7-py2.py3-none-any.whl
Installing collected packages: pytz
Exception:

    mkdir(name, mode)
OSError: [Errno 13] Permission denied: '/usr/local/lib/python2.7/site-packages/pytz-2016.7.dist-info'

我按照这个主题的接受答案但又得到了另一个错误:

sudo:pip: command not found

然后我发现它可能是因为路径设置错误(根据此页面.但我无法Just add ~/.local/bin to your path按照第二个答案的建议设置.

有人可以告诉我如何将垃圾箱添加到我的路径？我不知道.

还有一些信息:

[ec2-user@ip-172-31-28-178 ug]$ echo $PATH
/usr/local/bin:/bin:/usr/bin:/usr/local/sbin:/usr/sbin:/sbin:/opt/aws/bin:/home/ec2-user/.local/bin:/home/ec2-user/bin
[ec2-user@ip-172-31-28-178 ug]$ which pip
/usr/local/bin/pip
[ec2-user@ip-172-31-28-178 ug]$

Answer 1

secure_pathsudo 的默认值()在/etc/sudoers.中指定.

[ec2-user@ip-172-31-28-178 ~]$ sudo grep secure_path /etc/sudoers
Defaults    secure_path = /sbin:/bin:/usr/sbin:/usr/bin

由于pip在该路径中找不到,因此您将收到未找到的错误.PATH在运行时保留您sudo:

sudo env "PATH=$PATH" pip install pytz
