我试图配置Apache来运行我的sample Flask应用程序,但遇到了一个无法解决的问题。以下是我遵循的步骤(均为root用户,以避免任何权限问题):
wsgi文件:
activate_this = '/var/www/FlaskApp/venv/bin/activate_this.py'
execfile(activate_this, dict(__file__=activate_this))
import sys
import site
site.addsitedir('/var/www/FlaskApp/venv/lib/python2.7/site-packages')
site.addsitedir('/var/www/FlaskApp/venv/lib64/python2.7/site-packages')
sys.path.insert(0, '/var/www')
from FlaskApp import app as application
app.py:
from flask import Flask
app = Flask(__name__)
@app.route('/')
def hello_world():
return 'Hello World!'
if __name__ == '__main__':
app.run()
httpd.conf:
<VirtualHost *:80>
ServerName localhost
WSGIDaemonProcess FlaskApp user=ec2-user group=ec2-user threads=2
WSGIScriptAlias / /var/www/FlaskApp/wsgi.py
<Directory /var/www/FlaskApp>
Allow from all
</Directory>
</VirtualHost>
目录结构:(/var/www/FlaskApp/)

-rw-r--r-- 1 root root 356 Dec 8 23:41 wsgi.py
httpd Error\u日志中出错:

有人能帮我解决这个问题吗?谢谢
根据错误日志的第一行,您使用的是Python 2.6.9,但您的虚拟环境有Python 2.7的包。语法错误是Python 2.7中引入的判决理解。
mod_wsgi文档在这里讨论这个问题:https://modwsgi.readthedocs.io/en/develop/user-guides/virtual-environments.html#virtual-environment-and-python-version
正如furas所说,Python 2.7即将结束,因此您应该考虑在整个项目中升级到Python 3。
