运行flask应用时,Apache2的error.log
显示找不到flask_bootstrap
模块:
[wsgi:warn] mod_wsgi: Compiled for Python/2.7.11.
[wsgi:warn] mod_wsgi: Runtime using Python/2.7.12.
[mpm_event:notice] AH00489: Apache/2.4.18 (Ubuntu) mod_wsgi/4.3.0 Python/2.7.12 configured -- resuming normal operations
[core:notice] AH00094: Command line: '/usr/sbin/apache2'
[wsgi:error] mod_wsgi (pid=18587): Target WSGI script '/var/www/myapp/myapp.wsgi' cannot be loaded as Python module.
[wsgi:error] mod_wsgi (pid=18587): Exception occurred processing WSGI script '/var/www/myapp/myapp.wsgi'.

[wsgi:error] from flask_bootstrap import Bootstrap
[wsgi:error] ImportError: No module named flask_bootstrap
我已根据myapp.conf
配置了venv
<VirtualHost *:80>
ServerName yourdomain.com
ServerAdmin youemail@email.com
WSGIProcessGroup myapp
WSGIApplicationGroup %{GLOBAL}
WSGIScriptAlias / /var/www/myapp/myapp.wsgi
WSGIDaemonProcess myapp python-home=/var/www/myapp/myapp/venv
<Directory /var/www/myapp/myapp/>
Order allow,deny
Allow from all
</Directory>
ErrorLog ${APACHE_LOG_DIR}/error.log
LogLevel warn
CustomLog ${APACHE_LOG_DIR}/access.log combined
</VirtualHost>
该模块在系统范围内和venv中均可用:
root@host:/var/www/myapp# python
Python 2.7.12 (default, Dec 4 2017, 14:50:18)
[GCC 5.4.0 20160609] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> from flask_bootstrap import Bootstrap
>>> Bootstrap
<class 'flask_bootstrap.Bootstrap'>
还有......
root@host:/var/www/myapp# source myapp/venv/bin/activate
(venv) root@host:/var/www/myapp# python
Python 2.7.12 (default, Dec 4 2017, 14:50:18)
[GCC 5.4.0 20160609] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> from flask_bootstrap import Bootstrap
>>> Bootstrap
<class 'flask_bootstrap.Bootstrap'>
我注意到有一个关于2.7.11与2.7.12不匹配的警告,但是次要版本真的是问题所在吗?

根据the docs,将以下内容添加到myapp.wsgi
activate_this = '/var/www/myapp/myapp/venv/bin/activate_this.py'
execfile(activate_this, dict(__file__=activate_this))
没什么区别。

因此,在Graham说服我我的“修复”(将两行移到
<Directory>
指令中)并不是真正的修复,可能是其他地方出错的迹象之后,我决定深入挖掘。按照文档,特别是确认虚拟环境的位置,我惊讶地发现,当激活我的本地机上的虚拟环境(而不是通过wsgi应用程序):
当我期望它是:
我不知道这是怎么发生的。也许是作为
root
做所有初始工作的结果。不过,高兴地说,删除和重新制作虚拟环境,这次作为一个普通用户,一切似乎都很好。

**注意:**此答案在发布后被@Bridgey发现是错误的。请参见他的其他答案。
原来,问题出在那两行字上:
应该在
<Directory>
里面!因此,
myapp.conf
现在看起来如下所示:公平地说,这是根据文档中的示例。
非常感谢所有评论的人:)
