pip 安装在 usr/lib/python3.6/site-packages 而不是 ubuntu 服务器上的 virtualenv

Question

I'm having a problem when installing packages on my virtualenv.It all started when I upgraded my pip to the latest version. I tried to revert my pip version to where I find it stable. When I try to install, for example, django-tables2, it says:

Requirement already satisfied: django-tables2 in /usr/lib/python3.6/site-packages (2.3.1)
Requirement already satisfied: Django>=1.11 in /usr/local/lib/python3.6/dist-packages (from django-tables2) (2.2.4)
Requirement already satisfied: pytz in /usr/local/lib/python3.6/dist-packages (from Django>=1.11->django-tables2) (2019.2)
Requirement already satisfied: sqlparse in /usr/local/lib/python3.6/dist-packages (from Django>=1.11->django-tables2) (0.3.0)
WARNING: You are using pip version 19.3.1; however, version 20.1.1 is available.
You should consider upgrading via the 'pip install --upgrade pip' command.

But when I check my folder in my virtualenv, it doesn't show there. I tried some commands like which pip and which pip3 and it says this:

(unidaenv) root@UnidaWebApplication:/home/unidaweb/unidaproject# which pip
/home/unidaweb/unidaproject/unidaenv/bin/pip
(unidaenv) root@UnidaWebApplication:/home/unidaweb/unidaproject# which pip3
/home/unidaweb/unidaproject/unidaenv/bin/pip3
(unidaenv) root@UnidaWebApplication:/home/unidaweb/unidaproject#

I also tried pip list but I can't find the package that I installed to my virtualenv.

I'm getting a bad gateway error when I try to add it on my settings.py , I don't really know how to fix this but when I'm in the version of pip that I know was stable running my project, I don't get this error and I can install any package that I needed to my project. Any help would be much appreciated. I'm stuck on this for about a week, hoping that someone could help me with this issue.

Answer 1

virtualenvs can break occasionally especially if the somebody updated the python executable the virtualenv was based or some packages / shared libraries of it.

I'd suggest to try out with a new virtualenv. (delete the broken one and replace it)

Further.

for debugging I suggest to type following two commands: type -a python and type -a pip

In case your search path has some hidden surprises it could be safer to call python -m pip instead of python though in a properly setup virtualenv it shouldn't make a difference.
