如何避免找不到包“ github.com/golang/protobuf/jsonpb”错误

Question

I want to put my code inside a docker container, I have created dockerfile and when I run, I got an error

internal/server/handlers.go:16:2: cannot find package "github.com/lib/pq" in any of:
    /usr/local/go/src/github.com/lib/pq (from $GOROOT)
    /go/src/github.com/lib/pq (from $GOPATH)

but when I launch my code locally without docker by typing go run main.go everything is fine

Make sure you installed all your package inside container. Because your docker container is a different machine with your current computer. You need to make sure that all dependencies package installed in your docker image. For an Dockefile example, install my package at Dockerfile as you can see:

FROM golang:latest
# Create working folder
RUN mkdir /app
COPY . /app
RUN apt -y update && apt -y install git
RUN go get github.com/go-sql-driver/mysql
RUN go get github.com/gosimple/slug
RUN go get github.com/gin-gonic/gin
RUN go get gopkg.in/russross/blackfriday.v2
RUN go get github.com/gin-gonic/contrib/sessions
WORKDIR /app 

Now you run docker run -it -p 8080:8080 your_docker_image_name go run main.go should work.
