Error Running Solana Test Validator in WSL: Troubleshooting Guide

As a developer using the Solana blockchain, you are probably familiar with setting up a development environment to test and develop your applications. One of the most common challenges developers face is running the solana-test-validator command in WSL (Windows Subsystem for Linux). If you encounter any errors while running this command, don’t worry, we have you covered.

In this article, we will guide you through the steps to resolve issues and errors while running solana-test-validator in WSL.

Solana CLI Setup

Before we move on to troubleshooting, make sure that you have Solana CLI installed on your system. To do this:

• Download the Solana CLI installer from the [Solana website](

• Follow the installation instructions to install the CLI.

• Once installed, verify that the CLI is working by running solana keygen --help (if you are new to Solana).

Troubleshooting Steps

If you encounter errors when running ‘solana-test-validator’, try these troubleshooting steps:

• Verify your WSL installation: Make sure your WSL installation is configured correctly and working as expected.

• Update Solana CLI: Make sure you have the latest version of Solana CLI installed by running solana --version. If a newer version is available, update to the latest version.

• Check your testnet URL: Make sure you are using the correct testnet URL when setting up your development environment in the [Solana documentation]( The testnet URL should be instead of

• Check for Solana CLI configuration issues

  

  : In some cases, the Solana CLI may not be configured correctly. Try running solana account list --keyring=wire to see if there are any issues with your keyring configuration.

• Run solana test-validator with the correct command line flags: Make sure you are using the correct command line flag when running solana-test-validator. In particular, try passing the -t option followed by the path to your Solana testnet wallet directory (e.g. /path/to/testnet/wallet).

Example Use Case

Let’s say you have set up a new WSL environment with the following configuration:

• You have a Solana test wallet located at ~/.solana/wallets/testnet/wallet.json

• You are using the default version of Solana CLI (1.6.3)

• You have installed the latest version of Solana CLI

To resolve errors when running solana-test-validator, you need to:

• Update Solana CLI to the latest version by running curl -sSL | Solana installation

• Verify that the testnet URL is correct

• Run solana account list --keyring=wire to check for any issues with the keyring configuration

By following these steps, you should be able to resolve errors when running solana-test-validator in WSL and return to your Solana development environment.

Conclusion

Running solana-test-validator can sometimes cause errors when working in a WSL environment. By following the troubleshooting steps in this article, you should be able to identify and resolve issues with the Solana CLI configuration, keyring issues, or testnet URL configuration. Happy testing!
