The “go: cannot find main module error” occurs when the “compiler cannot locate the main package and function in your code”.
How to fix the “go:cannot find main module error”
Here are a few steps to follow:
Step 1: Check the file name
You must ensure the file containing the main function has the name main.go. The Go compiler only recognizes the main function if it is in a file named main.go.
Step 2: Verify the package declaration
Ensure that the package declaration is at the top of the main.go file is package main.
Step 3: Check the function signature
Ensure the main() function has the correct signature, func main().
Step 4: Verify the import statements
Ensure you have imported all necessary packages in the main() function.
Step 5: Set the GOPATH environment variable
The GOPATH environment variable should be set correctly to the location of your Go workspace.
Step 6: Rebuild the project
If all the above steps are correct, try rebuilding the project using the go build command.
If the build is successful, try running the project using the go run command.
I hope this helps you fix the error.
