我尝试安装以下python程序
https://bitbucket.org/OES_muni/massiveoes/src/master/
我得到以下错误：
python setup.py develop
/home/linux/.local/lib/python2.7/site-packages/setuptools/dist.py:474: UserWarning: Normalizing '1.001' to '1.1'
normalized_version,

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 13] Permission denied: '/usr/local/lib/python2.7/dist-packages/test-easy-install-547.write-test'
The installation directory you specified (via --install-dir, --prefix, or
the distutils default setting) was:
/usr/local/lib/python2.7/dist-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:
https://setuptools.readthedocs.io/en/latest/easy_install.html
Please make the appropriate changes for your system and try again.
