通常是虚拟环境的 env/xxx/Lib\site-packages 目录 还有个 env/xxx/tcl 目录，要使用修复后的版本
Put it in tcl folder (e.g your conda directory where you get this error –C:\Users<username>\AppData\Local\Continuum\miniconda3\tcl)
You will get rid of two types of of error:
Can’t find package error

添加数据 self.mlbSolution.insert('end' , *map (unicode, (row[1 ], row[2 ])))
删除选中项 item = self.mlbSolution.curselection() self.mlbSolution.delete(item[0 ])
选中 这里使用项目个数 - 2 来定位最后一个
self.mlbSolution.select_set(self.mlbSolution.item_count() - 2 )
清空 self.mlbMeasureResult.delete(0 , 'end' )
