How to Fix the 'cannot download, $GOPATH not set' Go Error?

Solution to "cannot download, $GOPATH not set" Error

Encountering the "package github.com/jehiah/json2csv: cannot download, $GOPATH not set" error when using the "go get" command indicates that the GOPATH environment variable is not configured. This variable specifies the location where Go stores its packages and workspace directories.

To resolve this error, follow these steps:

1. Set the GOPATH Variable:

   Open your shell and run the following command to set the GOPATH variable:

   export GOPATH="$HOME/your-workspace-dir/"

   Replace "your-workspace-dir" with the desired path for your Go workspace directory.

2. Add GOPATH to ~/.bashrc:

   To make the GOPATH setting permanent, add the following line to your ~/.bashrc file:

   export GOPATH="$HOME/your-workspace-dir/"

3. Restart Your Shell:

   Restart your shell to apply the changes to the environment variables.

4. Update PATH:

   Add the GOPATH/bin directory to your PATH environment variable by running the following command:

   export PATH=$PATH:$GOPATH/bin

5. Create Workspace Directories:

   Go will create three subdirectories in your GOPATH directory: src/, pkg/, and bin/.

6. Install json2csv:

   Now you can successfully install json2csv using the "go get" command:

   go get github.com/jehiah/json2csv

By following these steps, you should be able to download and install Go packages without encountering the "cannot download, $GOPATH not set" error.
