Package io/fs is not in goroot (/usr/local/go/src/io/fs)

by

Explanation:

When you encounter the error message “package io/fs is not in goroot (/usr/local/go/src/io/fs)”, it means that the package you are trying to import is not found in the Go standard library. This error typically occurs when you are using a version of Go that does not include the required package.

Starting from Go 1.16, the io/fs package was introduced to provide a framework for defining filesystem APIs. However, if you are using an older version, this package may not be available by default in your Go installation.

To resolve this issue, you have multiple options:

  1. Upgrade your Go installation to a version that includes the io/fs package.
  2. If upgrading is not feasible, you can try using a third-party package that provides similar functionality to io/fs. For example, the afero package is a commonly used alternative.
  3. If you don’t actually need the io/fs package and it was added unintentionally, you can simply remove the import statement from your Go source code.

Here’s an example illustrating the error message and one of the potential solutions:

// Example Go code with the io/fs package import
  package main

  import "io/fs" // This package is not found in Goroot

  func main() {
    // Your code here
  }

In the above example, if you are using an older version of Go, you will encounter the error. To resolve it, you can consider upgrading your Go installation or using an alternative package like afero:

// Example Go code with afero package import
  package main

  import "github.com/spf13/afero"

  func main() {
    // Your code here
  }

By following one of the suggested solutions, you should be able to resolve the "package io/fs is not in goroot" error in your Go code.
