各位开发者好。
如果您在上传或预览出现这种情况的话，【wxml 编译错误，错误信息：pages/index/index.wxml:279:113: Bad attr `wx:key` with message: unexpected token `em`.】
这个是源码出现问题，上述提示在具体的文件夹，具体的线上出现空格键。比如上述就是在pages/index/index.wxml文件里面的279线上第113个字符的em出现空格键。
把这个空格键进行删除，在按保存。然后还会出现这种相类似的文件夹中出现wx:key中*this 把*去掉在保存。直到你所有的this前没有*。这个小程序就大功告成了。希望能帮到你们。亲测。
哪位大神知道hbuilderx运行项目启动微信开发者工具后报这个错误，代码完全没问题，升级工具后就出现这个问题了，回退版本也不行

这是什么问题
导入项目后出现这个问题怎么解决

你好。我这个是什么问题呢
这个问题是真的坑😂半年没动过的老代码，打开就报错了，还要一个个文件把*都删掉
这个不行啊 大兄弟
截图看看什么提示
这个更好解决，删除那个*号即可
