[P12592 20:45:34.280 client.go:312 W] RPC failed transiently (retry in 1m4s): rpc error: code = Internal desc = prpc: sending request: Post "https://chrome-infra-packages.appspot.com/prpc/cipd.Repository/ResolveVersion": proxyconnect tcp: dial tcp [::1]:1080: connectex: No connection could be made because the target machine actively refused it. {"host":"chrome-infra-packages.appspot.com", "method":"ResolveVersion", "service":"cipd.Repository", "sleepTime":"1m4s"}C:\chromium>export DEPOT_TOOLS_UPDATE=0
'export' 不是内部或外部命令，也不是可运行的程序
