rust-msc-latest-linux 工具运行时crash #291

Closed teddyxiong53 closed 1 year ago

teddyxiong53 commented 1 year ago

测试平台

5.4.0-136-generic #153~18.04.1-Ubuntu SMP Wed Nov 30 15:47:57 UTC 2022 x86_64 x86_64 x86_64 GNU/Linux 非docker环境。手动安装的相关工具链。手动编译。

现象描述

重复执行rust-msc-latest-linux 命令，如果目录已经有pikascript-api目录，则改命令会crash掉。此时需要手动删掉pikascript-api目录再执行则正常。

我看了一下源码，就是rust操作fs的删除行为失败了。

有可能是权限问题，也可能是文件被占用了。试试加权限，或者用 wine 直接运行 exe

今天又没有复现了。之前原因应该就是删除目录失败。可以加一个错误检查，出错时给提示并返回，避免crash。
