title: -bash: sencha command not found
body: <p>I installed Sencha SDK and Sencha command on my mac-mini and done with some sample app.. but suddenly after some time when I tried to run sencha command on terminal, I got the response as '-bash: sencha command not found', I don't know why this was happened. Earlier I didn't find such type of response but now I got this error. Please tell me what are the possible scenarios for this thing to be happened.. Thanks for your help</p>
