project already exists delete and recreate Cordova (MacOS)

根据我的环境说明一下：
1、Cordova的目录:/Users/kevin/Projects/HTML5/cordova-2.4.0/cordova-android

2、AndroidSDK目录: /Users/kevin/TBB/adt-bundle-mac-x86_64/sdk

3、设置方法：
（1）Terminal: 定位到Cordova的目录。
       cd /Users/kevin/Projects/HTML5/cordova-2.4.0/cordova-android
 （2）设置环境变量
       export PATH=/Users/kevin/TBB/adt-bundle-mac-x86_64/sdk:/Users/kevin/TBB/adt-bundle-mac-x86_64/sdk/tools/:$PATH

 （3）执行 ./bin/create ~/Desktop/myapp com.myapp.special MyApp

特殊说明：

./bin/create /Users/kevin/CordovaProjects/Android/ChunMiaoPu com_chunmiaopu_android chunMiaoPuAndroid

会出现错误：

An unexpected error occurred: "$ANDROID_BIN" create project --target $TARGET --path "$PROJECT_PATH" --package $PACKAGE --activity $ACTIVITY >&/dev/null exited with 1

Deleting project...


只有执行如下才可以：./bin/create ~/CordovaProjects/Android/ChunMiaoPu com.chunmiaopu.android chunMiaoPuAndroid


~/MyWorkSpace/JiffAndroidApp 会自动创建JiffAndroidApp目录

devmatoMacBook-2:cordova-android kevin$ ./bin/create ~/MyWorkSpace/JiffAndroidApp me.jiff.AndroidApp JiffAndroidApp

An unexpected error occurred: ANDROID_BIN="${ANDROID_BIN:=$( which android )}" exited with 1

Deleting project...

devmatoMacBook-2:cordova-android kevin$ export PATH=/Applications/eclipseForADT-20130219/sdk:/Applications/eclipseForADT-20130219/sdk/tools/:$PATH  

devmatoMacBook-2:cordova-android kevin$ ./bin/create ~/MyWorkSpace/JiffAndroidApp me.jiff.AndroidApp JiffAndroidApp
