Question

我想做

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

使用面料。

如果我这样做

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＆＃39; /home/coby/.cache/pip/http'或其父目录不归当前用户所有，并且已禁用缓存。请检查该目录的权限和所有者。如果用sudo执行pip，你可能需要sudo＆＃39; -H标志。

后跟

的例外

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

Answer 1

在shell中，您在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。

您必须对结构做同样的事情：运行sudo()并在其中调用source，而不是在外面。

您当前的fab代码相当于

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

Fabric - 作为不同的用户运行，但非sudo
