[qiu8310]

这应该是 webpack 的问题吧，偶尔是会出现的。 我暂时无能为力哦

[zaaack]

@qiu8310 但是每次报错的文件都是 minapp 里的 parser.js, 怀疑里面发生了内存泄露。

[qiu8310]

这样呀，那有可能，你能定位出是哪个 wxml 文件么？

那个 parser 主要是解析 wxml 文件的，是有可能出现无限循环问题

[qiu8310]

可能是解析 wxml 文件时造成的，你能定位出这个文件可以把这 wxml 文件发给我

[zaaack]

home.wxml.zip

[zaaack]

不排除是我在编辑过程中的某个状态导致的。。

[qiu8310]

你上面的文件是可以正常解析的，好像没问题

[zaaack]

🤦‍♂️ 解析都是可以正常解析的，就是有时候时间一长就 oom 了，webpack 确实有内存泄露的问题，但是整个项目也不是很大，就是感觉有点频繁了..

[qiu8310]

一般来说，解析不成功都会报错的；而且 webpack 只会编译更新了的文件，所以我也是很奇怪。
