我有一个脚本：
#!/usr/local/bin/python
import cgi
import pymysql as MySQLdb
import os,sys,traceback
import cgitb
from xml.dom.minidom import Document
import site
from distutils.sysconfig import get_python_lib
import distutils.sysconfig
print "Content-type: text/html"
print
print os.environ['PYTHONPATH'].split(os.pathsep)
print os.environ['PATH'].split(os.pathsep)
print distutils.sysconfig.get_python_lib()
print os.sep.join([sys.prefix, 'lib', 'python' + sys.version[:3], 'site-packages'])
print(get_python_lib())
print sys.version
print sys.prefix
print MySQLdb.__dict__
print "Test complete"
print MySQLdb.VERSION
当我执行它时，我得到：
curl "http://box.com/cgi-bin/first.py"
['/usr/local/lib/python2.7/site-packages']
['/usr/local/bin/', '/usr/kerberos/sbin', '/usr/kerberos/bin', '/usr/local/bin', '/bin', '/usr/bin', '/usr/X11R6/bin']
/usr/local/lib/python2.7/site-packages

Test complete
注意 print MySQLdb.VERSION 值没有被打印出来。现在，当我在命令行中使用相同的程序时：

我不确定我应该做些什么额外的事情才能使 curl 调用（就像通过浏览器一样）也可以工作。问题是当我运行时它会出错：
curl "http://box.com/cgi-bin/first.py"
AttributeError: 'module' object has no attribute 'VERSION'
解决了！！！！
问题是 /usr/local/lib/python2.7/site-packages/pymysql 及其子目录中的文件确实具有执行权限。将它们更改为 755（全部）后，问题已解决。
