After 2.2.12 @tarojs/transformer-wx break built

[Eric-Guo]

#6001

准确的说，是这个PR导致的问题，目前降级到@tarojs/mini-runner到v2.2.11就可以了。

相关平台

微信小程序

小程序基础库: 2.11.3
使用框架: React

复现步骤

升级到2.2.12

期望结果

Build出来的程序可以运行

实际结果

loading 失败，运行时报错。

正常生成和非正常生成的：

-var _$indexKey = "jzzzz" + __index0;
+var _$indexKey = _$uid + __index0;

生成的代码里面没有_$uid，好神奇！

麻烦提供个 demo 看下

能加微信传给你吗？代码不方便开源。

好

暂时先把这个改动撤销了，2.2.13 正常，后续会看看这里应该如何调整

[dreamthen]

这边出现同样的问题，现在2.2.13还没发布是嘛？

[Eric-Guo]

已经发布了，阿里云同步这两天有问题，切换到官方就好了。
