setuptools错误python27 setup.py install：只读文件系统

我想在Bluehost帐户上安装Django。我使用了这些说明（[http://devget.net/misc/installing-django-1-5-1-with-python-2-7-4-on-bluehost/][1]）setuptools错误python27 setup.py install：只读文件系统

I已经安装了Python2.7.4。我接着安装setuptools：

cd ~ wget --no-check-certificate http://pypi.python.org/packages/source/s/setuptools/setuptools-0.6c11.tar.gz tar xzvf setuptools-0.6c11.tar.gz cd setuptools-0.6c11

文件被下载得到，但是当我尝试设置：

python27 setup.py install

I receive this error: running install error: can't create or remove files in install directory

The following error occurred while trying to add or remove files in the installation directory:
[Errno 30] Read-only file system: '/usr/lib/python2.6/site-packages/test-easy-install-800.write-test' 
The installation directory you specified (via --install-dir, --prefix, or the distutils default setting) was:
/usr/lib/python2.6/site-packages/ 
Perhaps your account does not have write access to this directory? If the installation directory is a system-owned directory, you may need to sign in as the administrator or "root" account. If you do not have administrative access to this machine, you may wish to choose a different installation directory, preferably one that is listed in your PYTHONPATH environment variable.

For information on other options, you may wish to consult the documentation at:

Please make the appropriate changes for your system and try again.
