Question

这最终成为OSx MySQL配置错误的原因：相对路径问题的不安全使用，但我留下原始问题，因为读者有相同的痕迹痕迹。

所以这是一个奇怪的问题 - 我试图在运行OSx的Mac上将Django部署到Apache，ModWSGI但是遇到以下错误消息：

目标WSGI脚本＆＃39; /Library/WebServer/local_biems/biems/wsgi.py'不包含WSGI应用程序

现在：

local_biems使用python manage.py runserver运行正常，没有沉默问题。所以我相信我的项目没有错误，可以部署。
测试应用程序local_blog运行服务器和我的虚拟主机配置运行正常 - 所以我假设Apache和MODWSGI正在愉快地一起玩。
local_biems和local_blog在/ Library / WebServer /中彼此并排，并具有相同的权限。
如果我更新虚拟主机中的文件路径，请重新启动apache并对网站进行重新加载，我会收到上述错误。
WSGI文件完全相同。

我可以尝试什么？我已经在get_wsgi_application（）

周围尝试了try / catch语句

try:
    application = get_wsgi_application()
    print 'WSGI without exception'
except Exception:
    print 'handling WSGI exception'
    # Error loading applications
    if 'mod_wsgi' in sys.modules:
        traceback.print_exc()
        os.kill(os.getpid(), signal.SIGINT)
        time.sleep(2.5)

但同样的问题。如果我删除它并坚持使用标准......

虽然我刚刚评论了所有（但是1）我的应用程序。奇怪的是，这个网站正在努力删除Ubuntu VPS没问题！

好的，所以我只是将数据库设置从local_biems复制到local_blog，我得到了MYSQL错误。

Answer 1

行。我追溯到 -

MySQL Improperly Configured Reason: unsafe use of relative path

虽然需要更新最后一个arg以反映新路径。

sudo install_name_tool -change libmysqlclient.18.dylib /
/usr/local/mysql/lib/libmysqlclient.18.dylib /
/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/_mysql.so

这可能是OSx特有的问题 - 这是在10.12.6。我不确定我是否会轻易找到它，因为SQL错误似乎只出现一次然后编译的文件报告了不同的错误。我发现使用

find . -type f -name '*.pyc' -exec rm {} +

删除所有已编译的文件帮助。

还必须将Debug设置为True才能获得信息量较少的500错误。

Django与ModWsgi和Apache不是一个有效的应用程序
