I was using the whole x/sys/unix package (https://github.com/golang/sys) not a simple main.go and its sub package. There are a couple checks for go.mod files in unusual places ($GOPATH/go.mod, $TMP/go.mod). 例如下面的是我们的项目目录： Learn more, cmd/go: "package … is not in GOROOT" is confusing in module mode when the package would exist in GOPATH mode. Set "trace": "log" and share the resulting logs in the debug console when logging an issue. or ["go"] or gopls prefixes. Now that you have created the go module, you need to make sure that every go file which is importing the package raindrops is using the full path to import the package. Sign up for a free GitHub account to open an issue and contact its maintainers and the community. The GOPATH is used to resolve imports, as well as to install packages outside the go tree. I have been through this many times and have seen lot of people struggling to fix this. For example, to access a function named “Rain()” from package “raindrops”, use “raindrops.Rain()”. Helpful pages include: Please answer these questions before submitting your issue. For an example of a test that uses this, see. This is a very efficient way to handle distributions of software, since the directories are predefined we need to focus less on managing different folders in our projects. Follow us on Twitter and Facebook and Instagram and join our Facebook and Linkedin Groups . they're used to log you in. Sign in set GOARCH=amd64 set GOBIN=C:\Users\Francesco\Go\bin set GOCACHE=C:\Users\Francesco\AppData\Local\go-build set GOEXE=.exe set GOFLAGS= set GOHOSTARCH=amd64 set GOHOSTOS=windows set GOOS=windows set GOPATH=C:\Users\Francesco\Go set GOPROXY= set GORACE= set GOROOT=c:\go set GOTMPDIR= set GOTOOLDIR=c:\go… Maybe? In this implementation, running go build fails with the below error. We use essential cookies to perform essential website functions, e.g. We use essential cookies to perform essential website functions, e.g. GOROOT is used to locate installation directories for external packages we install. This was going to be my next try :) Unfortunately I broke my hand. The go module expects the first part of the path as a domain name to maintain uniqueness in the package names. I am unable to reproduce the issue. Can you post the code or at least the import block @Helflym ? The error is obvious with gccgo (so also with version 1.12). Can you at least post the import block of your main go file? I do agree that having GOPATH under GOROOT isn't the best idea ever. in windows GOROOT can be C:\go. I am continuing analysis now. @Helflym I still have not be able to reproduce this. You signed in with another tab or window. Successfully merging a pull request may close this issue. Press J to jump to the feed. However, I'm not sure if the error from TIP is related or not. You signed in with another tab or window. I have tried all the combinations I can think of as far as file and import structure to cause this, but I get no errors. We use optional third-party analytics cookies to understand how you use GitHub.com so we can build better products. Now, we are going to take a look at what each one represents. r/golang: Gophers of the world unite! Since this example is not pushing code to any version control system like github.com, we are using fake.com as the domain name in the path. Setting GOPATH within GOROOT is definitely not a supported configuration, but maybe we should generate a better error for it. Building toolchain2 apparently uses this configuration. It's very unlikely that it'll ever occur with Golang as GOROOT as a true meaning. Go tooling comes with it already set up. It lets you create a go.mod file which can be created at the root of your directory structure, below which your go packages may be present in various subdirectories. So should it just print a helpful warning? To solve this issue, we will create a go module file named go.mod in the directory ‘medium’, using below steps. This is where Go modules come to the rescue. Change https://golang.org/cl/185540 mentions this issue: cmd/go: Warn when GOPATH is a subdir of GOROOT. Learn more, We use analytics cookies to understand how you use our websites so we can make them better, e.g. I agree the former error is not wrong, but it is pointing in the wrong direction. I don't think gorename, the underlying tool used in this case, supports module mode. Even when GOPATH is a sub-directory of GOROOT. What is GOROOT and GOPATH and the problem of go path export. @FiloSottile We can't exit. GitHub is home to over 50 million developers working together to host and review code, manage projects, and build software together. Maybe it can be adapted for AIX. It could be interesting to know why it does with this simple package but it doesn't with a complex package like x/sys/unix. This post will show you an example of how Go modules bring simplicity to package management in golang. This creates a file named go.mod which has a path to fake.com/medium. When developing go code with multiple packages, if your source files are not in $GOPATH/src directory, you may see below error while running go build. You signed in with another tab or window. In this example, we have two go files raindrop1.go and raindrop2.go in the package named ‘raindrops’. We’ll occasionally send you account related emails. But tool tests in module mode need a go.mod file, which cannot be checked into the tree (because it would be a module boundary; see #27852), and cannot not be written into the existing testdata directory because it may not be writable (see #28387). This post is not intended to provide details of Go modules. A GOROOT of /opt/freeware seems like a problem in general. The Go build and test cases are all going to be under $GOROOT/src though, so it doesn't help. You can always update your selection by clicking Cookie Preferences at the bottom of the page. golang/go#24661, For modules mode, we recommend gopls instead. GOPATH and GOROOT are two most essential PATHs in GoLang. In this small post I will tell you how to fix this problem. We use optional third-party analytics cookies to understand how you use GitHub.com so we can build better products. // Diagnose common mistake: GOPATH==GOROOT. Here’s an example, suppose a project is done under the src folder under GOPATH, then the go build command will create the executable in the bin directory in the GOPATH. Successfully merging a pull request may close this issue. You are using Go in modules mode (based on set GOMOD=D:\go_workspace\src\pink-api\go.mod). Note that the location of the go.mod file is already reported by go env. Go is looking in both GOROOT (install location), and GOPATH for dependencies, if you've saved your dependencies anywhere but these directories, it doesn't know where to find them unless you use something called go modules So if the check only happens in module mode, it should not actually affect any tests!
