Question

我有一个非常简单的BottlePy应用程序，它有一个使用subprocess.Popen启动新进程的路由。使用命令一切都很好：

mod_wsgi-express start-server app.wsgi

首先，在尝试apache配置时，我遇到了一个奇怪的异常，可能与pyMongo有关。

 File "/usr/local/opt/python/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/mongoengine/__init__.py", line 3, in <module>
    import fields
  File "/usr/local/opt/python/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/mongoengine/fields.py", line 6, in <module>
    import urllib2
  File "/usr/local/opt/python/Frameworks/Python.framework/Versions/2.7/lib/python2.7/urllib2.py", line 94, in <module>
    import httplib

    import io as _io
  File "/usr/local/opt/python/Frameworks/Python.framework/Versions/2.7/lib/python2.7/io.py", line 51, in <module>
    import _io
ImportError: dlopen(/usr/local/opt/python/Frameworks/Python.framework/Versions/2.7/lib/python2.7/lib-dynload/_io.so, 2): Symbol not found: __PyCodecInfo_GetIncrementalDecoder
  Referenced from: /usr/local/opt/python/Frameworks/Python.framework/Versions/2.7/lib/python2.7/lib-dynload/_io.so
  Expected in: flat namespace
 in /usr/local/opt/python/Frameworks/Python.framework/Versions/2.7/lib/python2.7/lib-dynload/_io.so

我的配置是：

的httpd.conf：

WSGIPythonPath "/usr/local/lib/python2.7/site-packages"

httpd.vhosts.conf：

<VirtualHost *:80>
    ServerName relferreira.com

    WSGIDaemonProcess relferreira user=relferreira group=staff processes=1 threads=5
    WSGIScriptAlias "/" "/Users/relferreira/Documents/app.wsgi"
    WSGIProcessGroup relferreira
    <Directory "/Users/relferreira/Documents/">
        WSGIProcessGroup relferreira
        WSGIApplicationGroup %{GLOBAL}
        Require all granted
    </Directory>
    ErrorLog /Users/relferreira/Documents/api/error-bottle.log
    CustomLog /Users/relferreira/Documents/api/access-bottle.log combined
</VirtualHost>

路线（简化）： 如您所见，我需要将路径传递给子流程，以便能够加载模块

@route('/extract')
def extract():
    try:

        script_path = .....
        command = .....
        env = os.environ.copy()
        env['PYTHONPATH'] = ":".join(sys.path) 

        proc = subprocess.Popen(['python', script_path] + command, env=env)
    except SystemExit as e:
        abort(400, 'Wrong parameters')

    return 'success'

otool -L：

command: otool -L /usr/local/lib/python2.7/site-packages/mod_wsgi/server/mod_wsgi-py27.so

返回：

/usr/local/lib/python2.7/site-packages/mod_wsgi/server/mod_wsgi-py27.so:
    /usr/local/opt/python/Frameworks/Python.framework/Versions/2.7/Python (compatibility version 2.7.0, current version 2.7.0)
    /usr/lib/libSystem.B.dylib (compatibility version 1.0.0, current version 1226.10.1)

我使用Homebrew安装了Python。我知道我应该使用virtualenv，put是一个遗留项目所以，我试图让它在没有它的情况下工作。
