嵌入式裝置(T507)執行qml程式提示module is not installed

T507裝置中執行qml編寫的程式，提示module未安裝，如下圖。

這是因為程式執行時未找到QML庫導致的，需要在qtenv.sh檔案或者系統環境變數中匯出QML庫在嵌入式裝置檔案系統中的位置，修改後如下：

1 export QML2_IMPORT_PATH=$QT_ROOT/qml

qtenv.sh檔案完整內容如下：

 1 export  QTDIR=/usr/local/Qt_5.12.5
 2 if [ -d $QTDIR ];then
 3 
 4     #source /dbusrun.sh
 5     #dbus-uuidgen > /etc/machine-id

22     do
23         DeviceName=`cat $InputDevices/name`
24         #echo $InputDevices name:$DeviceName
25         if [ $DeviceName == $TouchDevice ];then
26            TouchDeviceNum=${InputDevices##*input}
27            export QT_QPA_EVDEV_TOUCHSCREEN_PARAMETERS=/dev/input/event$TouchDeviceNum
28            echo "add "/dev/input/event$TouchDeviceNum "to Qt Application."
29            break
30         fi
31     done
32     if [ ! -n "$TouchDeviceNum" ]; then
33      echo "Error:Input device $TouchDevice can not be found,plz check it!"
