Question

我一直在阅读指南here，但我无法在Bluehost上部署Flask。

以下是venv中安装的软件包：

Flask           - 0.10.1       - active 
Jinja2          - 2.7.2        - active 
MarkupSafe      - 0.21         - active 
Python          - 2.7.3        - non-active development (/usr/local/lib/python2.7/lib-dynload)
Python          - 2.7.6        - active development (/usr/local/lib/python2.7/lib-dynload)
Werkzeug        - 0.9.4        - active 
flup            - 1.0.2        - active 
itsdangerous    - 0.24         - active 
pip 1.5.4 has no metadata
setuptools 2.2 has no metadata
wsgiref         - 0.1.2        - active development (/usr/local/lib/python2.7)
yolk            - 0.4.3        - active

我的.htaccess文件在public_html：

Options +ExecCGI
AddHandler fcgid-script .fcgi
RewriteEngine On
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule ^(.*)$ flask_hello_world.fcgi/$1 [QSA,L]

flask_hello_world.fcgi，也在public_html中：

    #!/home/REDACTED/venv/flask_hello_world/bin/python

    from flup.server.fcgi import WSGIServer
    from flask_hello_world_app import app as application

    WSGIServer(application).run()

flask_hello_world_app.py文件，也在public_html中：

from datetime import datetime
from flask import Flask
app = Flask(__name__)

@app.route('/')
def hello_world():
    return 'Hello World!'

@app.route('/the-time')
def the_time():
     cur_time = str(datetime.now())
     return cur_time + ' is the current time!  ...YEAH!'

if __name__ == '__main__':
    app.run()

执行flask_hello_world.fcgi时输出如下：

WSGIServer: missing FastCGI param REQUEST_METHOD required by WSGI!
WSGIServer: missing FastCGI param SERVER_NAME required by WSGI!
WSGIServer: missing FastCGI param SERVER_PORT required by WSGI!
WSGIServer: missing FastCGI param SERVER_PROTOCOL required by WSGI!

使用python解释器执行flask_hello_world.fcgi时输出如下：

  Traceback (most recent call last):
  File "flask_hello_world.fcgi", line 4, in <module>
    from flask_hello_world_app import app as application
  File "/home/REDACTED/public_html/flask_hello_world/flask_hello_world_app.py", line 2, in <module>
    from flask import Flask
  File "/usr/lib/python2.6/site-packages/flask/__init__.py", line 19, in <module>
    from jinja2 import Markup, escape
ImportError: No module named jinja2

Apache错误日志如下：

[Tue Apr 22 19:56:19 2014] [warn] [client xxx] (104)Connection reset by peer: mod_fcgid: error reading data from FastCGI server
[Tue Apr 22 19:56:19 2014] [error] [client xxx] Premature end of script headers: flask_hello_world.fcgi
[Tue Apr 22 19:56:19 2014] [error] [client xxx] exec used but not allowed in /home/REDACTED/public_html/500.shtml

我过去已经成功部署了Flask，所以此刻我有点不知所措。我想我错过了一些简单的东西，任何帮助都会受到赞赏。

编辑：这是一个权限/所有权问题，我发现我检查了suexec日志。

除了显而易见的是Jinja2 REALY安装，我的赌注是你的mod_wsgi找不到你的virtualenv。这可以解释Jinja2环境错误。

在mod_wsgi(Apache) deployment doc

的非常底部

如果你想使用mod_wsgi的虚拟环境，你必须这样做   稍微修改你的.wsgi文件。

将以下行添加到.wsgi文件的顶部：

activate_this =＆＃39; /path/to/env/bin/activate_this.py'

execfile（activate_this，dict（ file = activate_this））

这设置了   根据虚拟环境的设置加载路径。 <强>保持   请记住，路径必须是绝对的。
