在Bluehost上部署Flask时出现问题

Question

我一直在阅读指南here，但我一直无法在Bluehost上部署Flask。

下面是安装在VENV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文件中的public_html：

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

的flask_hello_world.fcgi，还的public_html：

#!/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() 

输出是执行flask_hello_world.fcgi当如下：

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! 
Status: 200 OK 
Content-Type: text/html; charset=utf-8 
Content-Length: 12 

Hello World!Unhandled exception in thread started by

lost sys.stderr

Unhandled exception in thread started by

输出与Python解释执行flask_hello_world.fcgi当如下：

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的错误日志如下：

[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 

我已成功de过去雇用了Flask，所以在这一点上我感到茫然。我想我缺少一些简单的东西，任何帮助将不胜感激。

编辑：这是一个权限/所有权问题，我发现我检查suexec日志。

除了显而易见的是Jinja2 REALY安装，我的赌注是你的mod_wsgi没有找到你的virtualenv。这将解释Jinja2环境错误。

在的mod_wsgi(Apache) deployment doc

如果你想使用你必须 mod_wsgi的小幅修改.wsgi文件的虚拟环境中的最底层。

以下行添加到您的.wsgi文件的顶部：

activate_this = '/path/to/env/bin/activate_this.py'

的execfile（activate_this，字典（文件 = activate_this））

这会根据虚拟环境的设置设置 加载路径。 记住 路径必须是绝对的。
