- 当前 Bug 的表现（可附上截图）

    代码是这样写的：

selectImage(){

    wx.showActionSheet({

        itemList: ['拍照', '相册'],

        success(res) {

            console.log(res.tapIndex);

            let sourcetype = ['camera','album'];

            wx.chooseImage({

                count: 1,

                sizeType: ['original', 'compressed'],

                sourceType: sourcetype[res.tapIndex],

                success(response) {

                // tempFilePath可以作为img标签的src属性显示图片

                    const tempFilePaths = response.tempFilePaths

                    console.log(tempFilePaths);

                    }

            })

            },

        fail(res) {

            console.log(res.errMsg)

        }

    })

},

在真机调试中不能唤起相机或者相册

- 预期表现

    可以打开系统相册或者相机
