raise bb.providers.NoProvider(item)

NoProvider: pseudo-native

原因：

项目中的base.bbclass和bitbake.conf不是从安装的bitbake工具目录（/opt/bitbake-1.17.0）中拷贝过来的，因为编译过yocto系统，bitbake被指定到了编译的yocto中的bitbake工具的位置了，故报错。

dragon@dragon-Long:~/Work/bitbake_test/bbTutorial/build$ which bitbake
/home/dragon/Work/poky-edison-6.0/scripts/bitbake

解决办法2种：

1、重新拷贝poky-edison-6.0目录中bitbake的base.bbclass和bitbake.conf到项目中

2、改变poky-edison-6.0目录的名字，并且重新指定bitbake工具的地址

export PATH=/opt/bitbake-1.17.0/bin:$PATH

export PYTHONPATH=/opt/bitbake-1.17.0/lib:$PYTHONPATH

然后执行就OK了。
