Resolving "hg" Executable Error for Remote Go Package Installation

The "exec: "hg": executable file not found in %PATH%" error occurs when attempting to install a remote Go package that is under Mercurial (hg) source control, but the hg executable is not present in the PATH. To resolve this issue and obtain remote packages, you must install Mercurial.

Despite navigating to the proper path and setting environment variables as instructed in the Golang tutorial, the installation process fails due to the absence of the hg executable. To address this:

Install Mercurial: Obtain the Mercurial software and install it.
Verify Installation: Ensure that the hg executable is successfully installed and added to your PATH by running the following command:

hg --version

Rerun go get: Re-execute the 'go get' command to download and install the remote package, specifying which source control system to use:

go get -u -v -d code.google.com/p/go.example/hello

Inspect Changes: The 'go get' command should clone the code from the Mercurial repository into the src/code.google.com/p/go.example directory within your GOPATH.
Test Package: After successfully installing the package, you can import and use it in your own code. For example, you can execute your custom hello.go code to demonstrate its functionality.

By following these steps, you can successfully obtain and use remote Go packages, broadening the scope of your development capabilities.
