protoc-gen-go：程序未找到或无法执行，尽管已安装

Question

我已经安装了 go 插件。当我尝试运行 events.proto 代码时，它仍然显示错误：

sudo go install google.golang.org/grpc/cmd/protoc-gen-go-grpc@latest
sudo go install google.golang.org/protobuf/cmd/protoc-gen-go@latest

文件结构：

pegasus@pegasus:~/Documents/eBPF/go-xdp-examples/gRPC_test$ tree
.
└── events.proto

1 directory, 1 file
pegasus@pegasus:~/Documents/eBPF/go-xdp-examples/gRPC_test$ 

生成go代码使用的命令：

pegasus@pegasus:~/Documents/eBPF/go-xdp-examples/gRPC_test$ sudo protoc --go_out=. --proto_path=/home/pegasus/Documents/eBPF/go-xdp-examples/gRPC_test --go_opt=paths=source_relative   --go-grpc_out=. --go-grpc_opt=paths=source_relative /home/pegasus/Documents/eBPF/go-xdp-examples/gRPC_test/events.proto
protoc-gen-go: program not found or is not executable
Please specify a program using absolute path or make sure the program is available in your PATH system variable
--go_out: protoc-gen-go: Plugin failed with status code 1.

在我的

~/.bashrc

里面

export PATH=$PATH:$(go env GOPATH)/bin

export PATH=$PATH:$HOME/go/bin
export PATH=$PATH:/usr/local/go/bin

进入二进制路径：

pegasus@pegasus:~$ which go
/usr/local/bin/go
pegasus@pegasus:~$ whereis go
go: /usr/bin/go /usr/lib/go /usr/local/bin/go /usr/local/go /usr/share/go /home/pegasus/go/bin/go /usr/share/man/man1/go.1.gz

GOPATH

pegasus@pegasus:~$ go env GOPATH
/home/pegasus/go

去环境输出：

pegasus@pegasus:~$ go env

我该如何修复它？我想解决

sudo go install

问题和 protoc-gen-go 问题。我应该在哪里设置我的GOBIN？ 由于我是新手，也许我问了一些天真的问题。

这是关于如何下载/使用 gRPC 的 go protoc 插件的一个很好的演练：https://grpc.io/docs/languages/go/quickstart/。
