imageClick(e) {
      wx.miniapp.shareImageMessage({
        imagePath: '存储图片的本地路径',
        thumbPath: '存储图片的本地路径',
        scene: 0, 
        success(res) {
          wx.showToast({
            title: '成功：分享图片',
          })
        },
        fail() {
          wx.showToast({
            title: '失败：分享图片',
          })
        }
      })
    }

需要open能力？能不能把这个写详细一点。完整代码太多了，就不贴出来了，我直接添加了点击事件，开发者工具报错

是什么原因呢？去哪里可以设置呢？没有文档吗？让开发者去猜吗？
