升级到2.6.8后ios出现JSON Parse error

分类：nvue

bug已修复

Nvue,v3编译器，纯nvue
19:06:55.955 SyntaxError: JSON Parse error: Unexpected identifier "undefined" ERROR
19:06:55.976 TypeError: undefined is not an object (evaluating 't[t.length-1].options') ERROR
升级后苹果系统（ios13.3.1）出现这个，android没事，什么都没改（没升级之前是正常的）
用调试器出来这两个，不知怎么排查
