Error of catkin build: Unable to find source space ....

[Happyjie1993]

catkin build unable to find source space if I made a directory within a sub-directory of the main folder, such as /home/computername/sub_folder/my_workspace/src. But it works well if I put the workspace folder just under the main folder like /home/computername/my_workspace/src. It's strange since I never have met this problem before (and catkin_make always works well). So what's wrong with my system setting?

Here is some of my system configuration information:
Operating System: Ubuntu 16.04 Linux
Python Version: Python 2.7.11
ROS Distro: kinetic

Please give a list of exact commands, copy-pasting the entire terminal output if possible. I can't tell what the issue is based on the information you've given me.

I had a similar problem, the following solved my problem:

rm -rf ~/.catkin_tools

According to the catkin tools documentation : The only constraint is that catkin workspaces cannot contain other catkin workspaces.

@oscar-lima Thank you so much~. Your method solved my problem! The .catkin_tools(a hidden folder) and the other workspaces can't be placed in the same folder (unluckily it happens to me :( ).

I got this problem when I was attempting to build tf2 on Windows bash (using conan.) Switching to the normal windows shell resolved the problem.
