proto文件正在导入“github.com/golang/protobuf/proto”,而不是“google.golang.org/protobuf/proto”,当“protoc --proto_path=proto proto/*.proto --go_out=plugins=grpc:pb”命令
导入文件
import (
fmt "fmt"
proto "github.com/golang/protobuf/proto"
math "math"
)
...

~go/bin/protoc-gen-go-grpc有版本
go: downloading google.golang.org/grpc/cmd/protoc-gen-go-grpc v1.3.0
go: downloading google.golang.org/grpc v1.58.2
go: downloading google.golang.org/protobuf v1.28.1
我所做的
最初安装
$ go install google.golang.org/protobuf/cmd/ email protected(https://stackoverflow.com/cdn-cgi/l/email-protection)
$ go install google.golang.org/grpc/cmd/ email protected(https://stackoverflow.com/cdn-cgi/l/email-protection)
在安装新软件包之前输入go clean -modcache,并使用注解@latest重新安装最新版本
go版本:go版本go1.21.1 Linux/amd 64 on Ubuntu 20.4
protoc --versionlibprotoc 3.6.1
使用apt安装protobuf-compiler和golang-goprotobuf
sudo apt install protobuf-compiler
sudo apt install golang-goprotobuf -dev
export PATH="$PATH:$(go env GOPATH)/bin"
我觉得问题就在这里,但我不知道该怎么解决,也不知道该怎么读

# github.com/golang/protobuf
(main module does not need package github.com/golang/protobuf)
编辑:我想我最初是使用go get -u github.com/golang/protobuf/proto安装的,但我使用rm -rf $(go env GOPATH)/pkg/mod/github.com/golang/protobuf/proto删除了二进制文件,并使用go install google.golang.org/protobuf/cmd/protoc-gen-go@latest和go install google.golang.org/grpc/cmd/protoc-gen-go-grpc@latest安装了新的二进制文件。它仍然使用旧的导入生成go文件
Edit 2:找不到protoc-gen-go --version,但protoc-gen-go-grpc --version为1.2.0。protoc --版本是libprotoc 3.6.1,其中是protoc-gen-go protoc-gen-go:/usr/bin/protoc-gen-go /home/hp/go/bin/protoc-gen-go/usr/share/man/man1/protoc-gen-go.1.gz

正如@puellanivis在https://github.com/golang/protobuf/issues/1451中提到的
Linux环境中的
$PATH
变量应该以/home/{username}/go/bin
开始,然后是/usr/bin
。这是因为我们需要在/usr/bin/protoc-gen-go
之前找到google.golang.org/gprc/cmd/protoc-gen-go-grpc@latest
。编辑
~/.bashrc
或~/.bash_profile
文件($vim ~/.bashrc
),然后手动导出整个路径环境。在我的情况下,我不得不加上
