git cloneしてきたlaunchファイルをroslaunchするとエラーが出ます

[石川友紀也]

一度PCをクリーンインストールし、ubuntu14.04にてros indigoの環境をros wikiを参考に入れました。
新しいパッケージを入れようと思い，git hubからjoy_twistをgit cloneし，
catkin_makeを実行してみたところ，エラーが発生しました.
エラーを解決する方法を教えてください．

発生したエラーは以下のとおりです

yukiya@yukiya-Vostro-460:~/catkin_ws/devel$ roslaunch joy_twist teleop_twist_joy.launch
[teleop_twist_joy.launch] is neither a launch file in package [joy_twist] nor is [joy_twist] a launch file name
The traceback for the exception was written to the log file

パスが通ってないのかと考え，source setup.bashを実行すると，エラーの内容が変わりました

yukiya@yukiya-Vostro-460:~/catkin_ws/devel$ source setup.bash

roslaunch から joy_twist パッケージが見えていないように思えます。

git clone は ~/catkin_ws/src 以下で実行しましたでしょうか。

また、 catkin_make は ~/catkin_ws で実行して、成功しましたでしょうか。

アドバイスを参考に確認してみたところ

必要なパッケージが足りていないのが原因でした．

ありがとうございました．
