Assets.car 解压工具 cartool 使用报错 segmentation fault cartool 解决方案

1  cartool 下载地址 https://github.com/steventroughtonsmith/cartool

由于在macOS Mojave系统上 之前代码会报错需要修改main.m中的代码修改如下图 参考地址 https://github.com/steventroughtonsmith/cartool/pull/26/commits/93c1cedd304bb4b4ad987bb1be10e453536b9300

main.m修改后的代码

使用方法 生成了可执行文件  放在usr/local/bin 下面

cartool  <path to Assets.car> [outputDirectory]

中间用空格隔开就好
