在运行Python程序时遇到权限错误，具体表现为'Permission denied: '/root/.cache/Python-Eggs''。这个问题通常是由于用户权限不足导致无法写入缓存文件夹。解决方案包括修改文件夹权限或者以管理员身份运行程序。

Python程序启动时报错：

unable to load app 0 (mountpoint='') (callable not found or import error)
*** no app loaded. going in full dynamic mode ***
Traceback (most recent call last):
  File "launchy_wsgi.py", line 12, in <module>
    application = launchy.Application(gac.list(), uimodules)
  File "*****************", line 48, in list
  *********************************
  File "/usr/local/lib/python2.7/site-packages/pkg_resources/__init__.py", line 1184, in extraction_error
    raise err
pkg_resources.ExtractionError: Can't extract file(s) to egg cache

The following error occurred while trying to extract file(s)
to the Python egg cache:

  [Errno 13] Permission denied: '/root/.cache/Python-Eggs'

The Python egg cache directory is currently set to:

  /root/.cache/Python-Eggs

Perhaps your account does not have write access to this directory?
You can change the cache directory by setting the PYTHON_EGG_CACHE
environment variable to point to an accessible directory.

  解决方法：到你的Python目录中的 
 site-packages，查看有没有*.egg文件，我的是pycurl-7.43.0.1-py2.7-linux-x86_64.egg 。 

 
 然后新建相同名称的目录，将文件内容解压进去，重启成功！示例如下： 

cd /usr/local/lib/python2.7/site-packages/
ll pycurl-7.43.0.1-py2.7-linux-x86_64.egg 
mv pycurl-7.43.0.1-py2.7-linux-x86_64.egg foo.zip
mkdir pycurl-7.43.0.1-py2.7-linux-x86_64.egg
cd pycurl-7.43.0.1-py2.7-linux-x86_64.egg/
unzip ../foo.zip
rm ../foo.zip
