作为一个不同的用户运行，但非sudo

Question

我想做

sudo su - some_user
source virtualenv/bin/activate
pip install psycopg2 gunicorn django-modeltranslation

用布料。

如果我做了

with sudo_settings(sudo_user="some_user"):
     with prefix("source virtualenv/bin/activate"):
         sudo("pip install psycopg2 gunicorn django-modeltranslation")

我得到了

目录'/home/coby/. cache /pip/http‘或其父目录不属于当前用户，缓存已被禁用。请检查该目录的权限和所有者。如果使用sudo执行pip，则可能需要sudo的-H标志。

之后是一个例外情况

UPD: pip install psycopg2 gunicorn --no-cache-dir工作。

Answer 1

在shell中，您可以在source之后运行sudo，这是正确的，因为source是一个影响当前环境的shell内置程序。

您必须对fabric进行同样的操作:运行sudo()并在其内部调用source，而不是在外部调用。

当前的fab代码等效于

source virtualenv/bin/activate
sudo su - some_user
pip install psycopg2 gunicorn
