Mod_wsgi Apache Bottle.py: 无法导入 python 模块 "server"

Question

我正在尝试同时使用 Bottle.py 和 mod_wsgi，但出现了一个我无法修复的奇怪错误。当我尝试发出 curl 请求时（"curl http://localhost/myapi/hello1") I get the error: "ImportError: No module named server". However, if I take out the "import server" line in my app.wsgi file and try "curl http://localhost/myapi/hello2" 它工作得很好。我尝试添加到 WSGIPythonPath、WSGIDaemonProcess 等，但没有任何效果。有没有人看到我可能正在做的事情错了？

注意：“/usr/local/www/wsgi-script”路径已成功添加到 sys.path，因此这不是问题所在。我在“/usr/local/www/wsgi-scripts”目录下也确实有一个init.py文件，权限都是777.

[root@my_vm httpd]# ls -lt /usr/local/www/wsgi-scripts/
total 8
-rwxrwxrwx. 1 root root  95 Mar 21 14:42 server.py
-rwxrwxrwx. 1 root root 318 Mar 21 14:37 app.wsgi
-rwxrwxrwx. 1 root root   0 Mar 20 19:53 __init__.py

使用版本：

Apache/2.4.6（红帽企业 Linux）

Python 2.7.5

瓶子 0.12.9

/usr/local/www/wsgi-scripts/server.py

import bottle
from bottle import route

@route('/hello1')
def hello():
    return "Hello World!"

/usr/local/www/wsgi-scripts/app.wsgi

import os
import sys
import bottle
from bottle import route

server_loc = "/usr/local/www/wsgi-scripts"
if not server_loc in sys.path:
    sys.path.insert(0, server_loc)

os.chdir(os.path.dirname(__file__))

print(sys.path)

@route('/hello2')
def hello():
    return "Hello World!\n"

import server
application = bottle.default_app()

/etc/httpd/conf.d/myapi.conf

<VirtualHost *:80>
    ServerName localhost

    WSGIScriptAlias /myapi /usr/local/www/wsgi-scripts/app.wsgi

    <Directory /usr/local/www/wsgi-scripts>
        Require all granted
    </Directory>

</VirtualHost>

添加我找到的对我有用的解决方案：

当我将 server.py 移动到目录内的另一个目录（又名 /usr/local/www/wsgi-scripts/server.py --> /usr/local/www/wsgi-scripts/inner_dir/server.py）时，执行 "import inner_dir.server" 而不是"import server"，它开始工作了。
