“sudo pip"时出错在 AWS ec2 实例上 [英] error when "sudo pip" on an AWS ec2 instance

问题描述

我正在尝试在 aws ec2 实例上运行一个小的 python 代码(它需要 pytz 和其他一些包).当我尝试安装 pytz 时，出现了一些错误:

I am trying to run a small python code (which requries pytz and some other packages) on a aws ec2 instance. When I tried to install pytz, I got some errors:

[ec2-user@ip-172-31-28-178 ~]$ pip install pytz
Collecting pytz

我遵循了本主题的公认答案，但是遇到另一个错误:

I followed the accepted answer of this topic but got another error:

sudo:pip: 命令未找到

后来发现可能是路径设置不对(根据此页面.但我无法按照第二个答案的建议 将 ~/.local/bin 添加到您的路径.

Then I found out it might be because the path setting is wrong (according to this page. But I could not manage to Just add ~/.local/bin to your path as suggested by the second answer.

有人可以告诉我如何将垃圾箱添加到我的路径中吗?我不知道.

Can someone show me how to add the bin to my path? I have no idea.

还有更多信息:

[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]$

推荐答案

sudo 的默认设置 (secure_path) 在 /etc/sudoers 中指定.

The default (secure_path) for sudo is specified in /etc/sudoers.

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

由于在该路径中未找到 pip，您将收到未找到错误.运行 sudo 时通过以下方式保留 PATH:

Since pip is not found in that path, you are getting the not found error. Preserve your PATH when running sudo by:

sudo env "PATH=$PATH" pip install pytz
