To fix the "go: cannot find GOROOT directory" error in WSL, you need to correct the GOROOT variable in your .profile and .bashrc files. Replace "$mnt" with "/mnt" in both files to specify the correct path to the GOROOT directory. After making the changes, log out and log back in to WSL for the changes to take effect.
When working with Go programming language in the Windows Subsystem for Linux (WSL), you may encounter the “go: cannot find GOROOT directory” error. This error typically arises when the
GOROOT environment variable is not correctly set in your system. In this article, we will guide you through the steps to resolve this issue.
Understanding the Error
Before we dive into the solution, it’s important to understand what this error means.
GOROOT is an environment variable that specifies the location of your Go installation directory. If this variable is not set correctly, the Go runtime will not be able to find the necessary libraries and tools, resulting in the “go: cannot find GOROOT directory” error.
Identifying the Problem
The root cause of this error is often a misconfiguration in the
.bashrc files. These files are used to set environment variables in a Unix-like operating system. The error indicates that the
GOROOT variable is set to
$mnt is not recognized as a valid directory.
How to Fix the Error
To fix this error, you need to correct the
GOROOT variable in your
.bashrc files. Here are the steps to do it:
Step 1: Open the Configuration Files
You can use any text editor to open the
.bashrc files. If you’re using a command-line text editor like
nano, you can open these files using the following commands:
Step 2: Correct the GOROOT Variable
In both files, find the line that sets the
GOROOT variable. It should look something like this:
/mnt so that the line looks like this:
$mnt in the original line is being treated as a variable, but it’s not set to anything, so it returns nothing. Replacing
/mnt specifies the correct path to the
Step 3: Save and Close the Files
After making the changes, save and close the files. If you’re using
nano, you can do this by pressing
Y to confirm the changes, and finally
Enter to exit.
Step 4: Log Out and Log Back In
For the changes to take effect, you need to log out of your WSL session and then log back in. You can do this by closing your WSL terminal and reopening it.
Testing the Solution
After logging back into WSL, you can test if the solution worked by running the
go version command. If the
GOROOT variable is set correctly, this command should return the version of Go installed on your system.
In this article, we’ve explained how to fix the “go: cannot find GOROOT directory” error in WSL by correcting the
GOROOT variable in your
.bashrc files. Remember, it’s generally recommended to use the
.profile file for environment variable configurations in WSL, as the
.bashrc file is meant for configuring the Bash shell specifically and may not be loaded in all cases. Always ensure that your environment variables are correctly configured to avoid such errors.
The GOROOT environment variable specifies the location of the Go installation directory. It is used by the Go runtime to find the necessary libraries and tools.
You can check the value of the GOROOT variable by running the
echo $GOROOT command in your WSL terminal. This will display the directory path set as the GOROOT.
No, the GOROOT variable should be set to the correct Go installation directory. It should point to the root directory of your Go installation, where the
src directories are located.
It is generally recommended to set the GOROOT variable in the
.profile file in WSL. This file is loaded when you start a new WSL session and ensures that the variable is set correctly for all processes. However, you can also set it in the
.bashrc file if needed.
Yes, after making changes to the GOROOT variable in the configuration files, you need to log out of your WSL session and then log back in for the changes to take effect. This ensures that the updated variable is loaded correctly.
If the error persists even after correcting the GOROOT variable, you can try reinstalling Go and ensuring that you set the GOROOT variable correctly during the installation process. Make sure to follow the official Go installation instructions for your operating system.
