Question

我正在尝试升级我的项目以使用Go模块进行依赖项管理。我认识到这是一项新功能/实验功能。我遇到错误：cannot find module providing package。

我的go.mod当前显示为：

require (
    github.com/bugsnag/bugsnag-go v1.5.1
    github.com/bwmarrin/discordgo v0.19.0
    github.com/jonas747/dshardmanager v0.0.0-20180911185241-9e4282faed43
)

我的Dockerfile：

FROM golang:1.12-alpine
RUN mkdir /app
WORKDIR /app
ADD src/ /app

ENV CGO_ENABLED=0

# Building requires git because we're pulling a dependency by commit hash
RUN apk add --no-cache --update git \
    && go build ./... \
    && apk del git

CMD ["/app/main"]

构建时失败，并显示：

cannot load github.com/bugsnag/panicwrap: cannot find module providing package github.com/bugsnag/panicwrap

当我查看https://web.archive.org/web/20151128202604/http://aspnetupload.com/Upload-File-POST-HttpWebRequest-WebClient-RFC-1867.aspx时，没有看到go.mod文件。该错误是否表示此依赖项不支持模块？

您做错了，因为它可以工作。它不需要go.mod即可用于基于go.mod的应用程序：

nrxr at lise in ~/code/src/github.com/nrxr/stack
$ go mod init
go: creating new go.mod: module github.com/nrxr/stack

nrxr at lise in ~/code/src/github.com/nrxr/stack
$ go get github.com/bugsnag/bugsnag-go
go: finding github.com/bugsnag/bugsnag-go v1.5.1
go: downloading github.com/bugsnag/bugsnag-go v1.5.1
go: extracting github.com/bugsnag/bugsnag-go v1.5.1
go: finding github.com/bugsnag/panicwrap v1.2.0
go: downloading github.com/bugsnag/panicwrap v1.2.0

go: extracting github.com/kardianos/osext v0.0.0-20190222173326-2bc1f35cddc0

nrxr at lise in ~/code/src/github.com/nrxr/stack
$ cat go.mod
module github.com/nrxr/stack

go 1.12

require (
        github.com/bugsnag/bugsnag-go v1.5.1 // indirect
        github.com/bugsnag/panicwrap v1.2.0 // indirect
        github.com/gofrs/uuid v3.2.0+incompatible // indirect
        github.com/kardianos/osext v0.0.0-20190222173326-2bc1f35cddc0 // indirect
)

也许再试一次？尝试一下我刚刚在这里使用的内容。

如何使用Go模块通过提交哈希或分支拉取依赖项？
