Error: Anchor Wallet Not Set On Solana Node

The error message indicates that the Anchor_wallet 'Environment variable is not set, which is causing an issue with setting up a connection to a solana cluster. This can be frustrating, especially when working with anchor projects.

Understanding the Error

When you run your application or script, it attempts to connect to a solana cluster using theConnectionity Provided by the Anchor SDK. However, without the necessary environment variables set, the connection attempt fails.

Solution: Setting Environment Variables

To resolve this issue, you need to ensure that the Anchor_wallet 'Environment variable is set on your Solana Node. Here's how to do it:

  • check the node version : ensure that your solana node version is compatible with anchor. You can check the version using the following command:

Bash

solana -cli -v

`

  • Set Environment Variable On Your Node :

You can set an environment variable directly in your operating system. Here’s how to do it for Linux and MacOS:

Linux:

  • Create a new file named .env with the following content:

`Makefile

Anchor_wallet = “Your-Anchor-Wallet-Password”

`

  • Set the Anchor_wallet 'Environment variable in your Shell Configuration File (E.G., ~/.Bashrc or ~/.zshrc). Add the following line to set the variable:

`Bash

Export Anchor_wallet = “Your-Anchor-Wallet-Password”

`

  • Restart your terminal or run source ~/.bashrc to apply the Changes.

MacOS:

  • Create a new file named .env with the following content:

`Makefile

Anchor_wallet = “Your-Anchor-Wallet-Password”

`

  • Set the Anchor_wallet 'Environment variable in your Shell Configuration File (E.G., ~/.Bash_Profileor~/.zshrc). Add the following line to set the variable:

Bash

Export Anchor_wallet = “Your-Anchor-Wallet-Password”

`

Verify Environment Variable

After setting the environment variable, verify that it is present by running the following command:

`Bash

echo $ anchor_wallet

`

If you see the value of your Anchor_wallet Environment variable, it means everything is working as expected.

Next steps:

Once you’ve set the environment variable, you should be able to connect to a solana cluster using the Anchor SDK. Make sure to check the official anchor documentation for any additional configuration or requirements specific to your use case.
