Question

我在ubuntu 15.10上安装了Django和mod_wsgi-express。基本上（注意我做了不以root身份执行此操作）：

~/.local/bin $ ./mod_wsgi-express start-server ~/mysite/mysite/wsgi.py

接下来我做了：

~/mysite/mysite/wsgi.py

其中：[Thu Mar 24 22:26:24.638043 2016] [wsgi:error] [pid 19469:tid 139785018738560] mod = importlib.import_module(self.SETTINGS_MODULE) [Thu Mar 24 22:26:24.638070 2016] [wsgi:error] [pid 19469:tid 139785018738560] File "/usr/lib/python2.7/importlib/__init__.py", line 37, in import_module [Thu Mar 24 22:26:24.781030 2016] [wsgi:error] [pid 19469:tid 139785018738560] __import__(name) [Thu Mar 24 22:26:24.781148 2016] [wsgi:error] [pid 19469:tid 139785018738560] ImportError: No module named mysite.settings [Thu Mar 24 22:26:27.590300 2016] [wsgi:error] [pid 19469:tid 139784895194880] [remote 92.243.236.53:24636] mod_wsgi (pid=19469): Target WSGI script '/tmp/mod_wsgi-localhost:8000:1000/handler.wsgi' cannot be loaded as Python module.来自我上传到服务器上方目的地的sample project。但是当我尝试访问网站时出现错误（内部服务器错误）。当我查看日志时，我看到：

os.environ["DJANGO_SETTINGS_MODULE"] = "mysite.settings"

所以似乎无法找到 mysite.settings /不在Python PATH上（文件〜/ mysite / mysite / settings.py 确实存在）。

基于： https://docs.djangoproject.com/en/1.9/howto/deployment/wsgi/

我试图添加：

import sys
#Wrong!
#sys.path.append("/home/user/mysite/mysite")

#Correct
sys.path.append("/home/user/mysite")

但它没有帮助。我还尝试将以上路径添加到示例项目到python路径： https://code.djangoproject.com/wiki/PythonPath

但同样的错误。我错过了什么？

问题出在包含路径中：

    //Convert your photo to a bitmap
    Bitmap photoBm = (Bitmap) "your Bitmap image";
    //get its orginal dimensions
    int bmOriginalWidth = photoBm.getWidth();
    int bmOriginalHeight = photoBm.getHeight();
    double originalWidthToHeightRatio =  1.0 * bmOriginalWidth / bmOriginalHeight;
    double originalHeightToWidthRatio =  1.0 * bmOriginalHeight / bmOriginalWidth;
    //choose a maximum height
    int maxHeight = 1024;
    //choose a max width
    int maxWidth = 1024;
    //call the method to get the scaled bitmap
    photoBm = getScaledBitmap(photoBm, bmOriginalWidth, bmOriginalHeight,

Answer 1

将此添加到 wsgi.py 文件

path = '/home/path/to/project'
if path not in sys.path:
    sys.path.append(path)

设置前

os.environ.setdefault("DJANGO_SETTINGS_MODULE", "mysite.settings")

Answer 2

请尝试：


    import os
    import sys
    BASE_DIR = os.path.dirname(os.path.dirname(os.path.abspath(__file__)))
    sys.path.append(BASE_DIR)
    os.environ['DJANGO_SETTINGS_MODULE'] = 'YOURAPP.settings'
    os.environ.setdefault("DJANGO_SETTINGS_MODULE", "YOURAPP.settings")

这适用于主项目目录中的脚本..

Answer 3

问题出在包含路径中：

import sys
#Wrong!
#sys.path.append("/home/user/mysite/mysite")

#Correct
sys.path.append("/home/user/mysite")

Answer 4

当我尝试将Windows项目移动到Debian时，我也遇到了这个错误。

import sys
sys.path.append("your project path")

Answer 5

此外，如果您使用的是Visual Studio，请检查Django的应用程序属性是否与您期望的设置模块匹配。默认情况下，它设置为$（MSBuildProjectName）.settings，这对我来说是一个问题，因为我的项目名称和应用名称不一样。

您可以通过在解决方案资源管理器中右键单击您的应用并点击＆＃34;属性＆＃34;来找到此设置。然后是左边的Django标签。

ImportError：没有名为mysite.settings的模块（Django）
