I'm trying to install ROS in a CentOS 7.0. I did these steps:

sudo yum install python-rosdep
sudo pip install rosinstall-generator
sudo yum install python-wstool python-rosinstall @buildsys-build
rosinstall_generator desktop_full --rosdistro kinetic --deps --wet-only --tar > kinetic-desktop-full-wet.rosinstall

But when I did the following:

 [me@localhost ros_catkin_ws]$  wstool init -j8 src kinetic-desktop-full-wet.rosinstall

And I get:

ERROR: Cannot find required rosinstall library version, check your installation (also of vcstools) is up-to-date. One frequent cause is that rosinstall 0.5 is still installed in /usr/local/lib.
No module named dateutil.parser

I have tried this:

[me@localhost ros_catkin_ws]$ python -c "import rosinstall; print rosintall.__version__"

And I get:

Traceback (most recent call last):
  File "<string>", line 1, in <module>
  File "/usr/lib/python2.7/site-packages/rosinstall/__init__.py", line 33, in <module>
    import wstool.helpers
  File "/usr/lib/python2.7/site-packages/wstool/helpers.py", line 37, in <module>
    from wstool.config_elements import SetupConfigElement

    from vcstools.vcs_abstraction import get_vcs_client
  File "/usr/lib/python2.7/site-packages/vcstools/__init__.py", line 44, in <module>
    from vcstools.svn import SvnClient
  File "/usr/lib/python2.7/site-packages/vcstools/svn.py", line 48, in <module>
    import dateutil.parser  # For parsing date strings
ImportError: No module named dateutil.parser

By the way /usr/local/lib is empty.

Any idea about this error?

I also run:

[me@localhost ros_catkin_ws]$ python -c "import dateutil"

With the error:

Traceback (most recent call last):
  File "<string>", line 1, in <module>
ImportError: No module named dateutil
