Python 在Bluehost上部署Flask时出现问题

我一直在阅读指南，但无法在Bluehost上部署Flask

以下是安装在venv中的软件包：

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

公共html中的My.htaccess文件：

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

    #!/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()

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()

flask_hello_world.fcgi，也在public_html中：

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

    #!/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()

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()

flask_hello_world_app.py文件，也是公共html格式：

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

    #!/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()

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!

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

我过去已经成功地部署了Flask，所以现在我有点不知所措。我想我错过了一些简单的事情，任何帮助都将不胜感激

编辑：我在查看suexec日志时发现这是一个权限/所有权问题。

除了明显的是真的安装了Jinja2之外，我打赌你的mod_wsgi找不到你的virtualenv。这可以解释Jinja2环境错误

在最底层

如果您想使用带有mod_wsgi的虚拟环境，您必须 稍微修改一下.wsgi文件

将以下行添加到.wsgi文件的顶部：

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

execfile（激活这个，dict（文件=激活这个））

这就建立了 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。

谢谢你的回复。这部分是一个venv问题，特别是由于权限问题而访问它。
