解决mason.nvim的[Core Utils]警告及pyright安装失败问题求助

大家好，我最近尝试用mason.nvim安装pyright时遇到了麻烦，安装一直失败，具体错误日志如下：

Failed

ڌ pyright

▼ Displaying full log

spawn: npm.cmd failed with exit code - and signal -. npm.cmd is not executable

一开始我查到pyright需要依赖Node.js，于是赶紧安装了Node.js，但问题还是没解决。之后我运行:Mason和:checkhealth命令，看到了一堆警告和错误，整理出来给大家看看：

• rhs:

最让我摸不着头脑的是那个pwsh的ERROR——我明明就是在PowerShell里运行nvim的，为什么会提示pwsh不可用呢？有没有大佬能帮忙分析下这些问题该怎么解决，尤其是pyright安装失败的核心问题，谢谢大家！
