[英]virtualenv with python interpreter newer than systemwide interpreter
[英]website using default python interpreter instead of install virtualenv interpreter
我已經在centos上安裝了python 2.7。
我已經創建並激活了與此解釋器關聯的virtualenv。
我的路徑如下所示:
/home/ec2-user/django-venv/bin:/usr/local/bin:/bin:/usr/bin:/usr/local/sbin:/usr/sbin:/sbin:/opt/aws/bin:/home/ec2-user/bin
當我訪問我的網站時,出現以下錯誤,表明它正在使用舊版本的python:
mod_wsgi (pid=19386): Exception occurred processing WSGI script '/var/www/html/-django//wsgi.py'.
Traceback (most recent call last):
File "/var/www/html/-django//wsgi.py", line 23, in <module>
from django.core.wsgi import get_wsgi_application
File "/usr/lib/python2.6/site-packages/django/core/wsgi.py", line 2, in <module>
from django.core.handlers.wsgi import WSGIHandler
File "/usr/lib/python2.6/site-packages/django/core/handlers/wsgi.py", line 11, in <module>
from django import http
File "/usr/lib/python2.6/site-packages/django/http/__init__.py", line 2, in <module>
from django.http.request import (HttpRequest, QueryDict,
File "/usr/lib/python2.6/site-packages/django/http/request.py", line 11, in <module>
from django.conf import settings
File "/usr/lib/python2.6/site-packages/django/conf/__init__.py", line 9, in <module>
import importlib
ImportError: No module named importlib
我這樣創建了virtualenv:
virtualenv --python=/usr/local/bin/python2.7 django-venv
然后,我像這樣激活它:
source django-venv/bin/activate
當我啟動“哪個python”時,我得到以下輸出:
~/django-venv/bin/python
我的Apache httpd.conf條目如下所示:
Alias /static/ /var/www/html/django/shared/static/
<Directory /var/www/html/django/shared/static/>
Order deny,allow
Allow from all
</Directory>
WSGIScriptAlias / /var/www/html/django/wsgi.py
WSGIPythonPath /var/www/html/django
<Directory /var/www/html/django>
<Files wsgi.py>
Order deny,allow
Allow from all
</Files>
</Directory>
但是我仍然得到上面的錯誤,它正在使用舊的python版本2.6
我如何讓我的網站使用指向正確位置的virtualenv?
我只使用manage.py startproject
生成的wsgi.py
文件,然后將以下內容放入我的httpd conf文件中:
WSGIScriptAlias / /full/path/to/wsgi.py
WSGIPythonPath /full/path/to/django/project:/full/path/to/django-venv/lib/python2.7/site-packages
官方文檔對此進行了介紹 。
如果僅在外殼程序中運行它,則只會影響該外殼程序會話,甚至在兩次登錄之間都不會持續存在,更不用說會影響任何系統范圍的服務,例如Apache。
通常,您會在wsgi.py中放入一些內容:
activate_this = '/path/to/virtualenv/bin/activate_this.py'
execfile(activate_this, dict(__file__=activate_this))
