用了樓主的固件，安裝資源庫沒有的軟件（gevent）就會出現以下錯誤：

已失敗並回傳代碼 255 和錯誤訊息
//user/lib/opkg/info/python-greenlet.postinst:line 4: default_postinst: not found
//user/lib/opkg/info/gevent.postinst:line 4: default_postinst: not found
Collected errors;
*pkg_run_script: package "python-greenlet"postinst script returned status 127.
*opkg_configure: python-greenlet.postinst returned 127.
*opkg_run_script: package "gevent"postinst script returned status 127.
*opkg_configure: gevent.postinst returned 127.

但安裝其它資源庫有的軟件就正常，路由器跑goagent，現在就剩下libevent2，python-greenlet，gevent這三個無法安裝，求解答！！！！！！！！！！！！！！！
