roscd cannot find the package

edit

Everytime I compile a package I'm working on, or try to use a new package, ROS cannot find the package. I've even restarted from scratch. For example, this afternoon I'm trying to run a publisher for an imu. So I started from scratch because nothing is working, again. After 30 minuts of looking for a mistake, googling, etc. it just starts to work. This is what I'm doing:

myuser@mypc:$ cd ros
myuser@mypc:$ rm -rf *
myuser@mypc:$ mkdir src
myuser@mypc:$ cd src
myuser@mypc:$ catkin_init_workspace
myuser@mypc:$ cp -r ~/develeopment/imu .
myuser@mypc:$ cd ..
myuser@mypc:$ catkin_make
