代理設(shè)置全局也不行，后面發(fā)現(xiàn)給rust cargo設(shè)置代理即可
如果出現(xiàn)跟我一樣的情況，可以試下，我改完之后就可以了

如果出現(xiàn)該錯(cuò)誤，cd進(jìn)入項(xiàng)目的src-tauri文件夾，運(yùn)行cargo update

會(huì)發(fā)現(xiàn)出現(xiàn)同樣的錯(cuò)誤

這時(shí)候只要在 C:\Users\用戶名.cargo 下創(chuàng)建 config 文件（可以先創(chuàng)建config.txt文件，填充內(nèi)容后刪除后綴）
內(nèi)容設(shè)置

[http]
proxy = "127.0.0.1:7890"

[https]
proxy = "127.0.0.1:7890"

現(xiàn)在重新運(yùn)行會(huì)發(fā)現(xiàn)就正常了

第一次用tauri，發(fā)現(xiàn)好多錯(cuò)誤Google都找不到....
