Fixing ‘lnd Command not found’ Error After Installing from Source

The output:

If you have installed lnd (Lightning Network Daemon) from source, you may encounter an error where the ‘lnd’ command is not found. This typically occurs after you have successfully installed lnd on your system, but when you try to run it, you get a message saying ‘lnd: command not found’.

This error can occur for a number of reasons, including incorrect installation paths, missing dependencies, or incorrect environment variables. In this article, we will examine some of the possible causes of this error and provide solutions to help you resolve it.

Possible causes:

There are several reasons why you may encounter the “lnd: command not found” error after installing from source. Here are some of the more common ones:

Incorrect installation paths:

One of the most common causes of this error is an incorrect installation path. When you install lnd from source, you must specify the installation path where the binaries will be installed. If you do not specify the correct path, the binaries will not be installed in the correct location and you will get the error ‘lnd: command not found’.

To fix this problem, make sure you specify the correct installation path when you install lnd from source. You can do this by running the following command:

make install PREFIX=/usr/local
This command installs the lnd binaries in the /usr/local/bin directory. If you want to install the binaries in a different directory, you can specify the path.

Missing dependencies:

Another common cause of the ‘lnd: command not found’ error is missing dependencies. When you install lnd from source, it requires several dependencies to be installed on your system. If these dependencies are missing, you will not be able to run the ‘lnd’ command.

To solve this problem, you need to make sure you have all the required dependencies installed on your system. You can check the dependencies required by lnd by following the installation instructions in the lnd repository.

Solutions:

Here are some solutions you can try to fix the ‘lnd: command not found’ error after installing from source:

Check the installation path:

The first solution is to check the installation path and make sure that the lnd binaries are installed in the correct location. You can do this by running the following command:

whereis lnd

This command will show you the location of the lnd binary on your system. If the binary is not in the /usr/local/bin directory, you may need to reinstall lnd and specify the correct installation path.

Check dependencies:

The second solution is to check the dependencies and make sure that all the required packages are installed on your system. You can do this by running the following command

ldd $(which lnd)

This command will show you the dependencies required by the lnd binary. If any of the dependencies are missing, you need to install them on your system.

Update environment variables:

The third solution is to update the environment variables to include the path to the lnd binary. You can do this by adding the following line to your .bashrc file

export PATH=$PATH:/usr/local/bin

This will add the /usr/local/bin directory to your system’s PATH variable, allowing you to run the ‘lnd’ command from anywhere on your system.

Reinstall LND:

If none of the above solutions work, you may need to reinstall lnd from source. Before doing so, make sure you have followed all the installation instructions and that you have all the necessary dependencies installed on your system.

At the end:

The ‘lnd: command not found’ error after installing from source can be frustrating, but it is usually caused by a simple configuration problem. By following the solutions outlined in this article, you should be able to resolve this error and start using lnd to power your Lightning network node.
