Ubuntu 20.04 Terminal Has No Prompt After Setting Up Node for Angular Environment

Are you experiencing issues with your Ubuntu 20.04 terminal after setting up Node.js for an Angular environment? If you're seeing a blank terminal with no prompt, you're not alone. This issue can be frustrating, especially when you're trying to work on a project and can't enter commands. In this article, we'll explore the possible causes of this problem and provide step-by-step solutions to get your terminal up and running again.

When you open a terminal in Ubuntu 20.04, you expect to see a prompt where you can enter commands. However, in your case, the terminal is blank, and pressing any key doesn't seem to do anything. This issue can be caused by a variety of factors, including:

Node.js installation issues: If Node.js was not installed correctly, it can cause problems with the terminal.
Angular environment setup issues: If the Angular environment was not set up correctly, it can also cause issues with the terminal.
Terminal configuration issues: The terminal configuration can also be a cause of this issue.

To troubleshoot this issue, let's go through some steps to identify and fix the problem.

Step 1: Check the Terminal Configuration

The first step is to check the terminal configuration. You can do this by opening a new terminal and typing the following command:

echo $PS1

This command will display the value of the PS1 variable, which is responsible for setting the prompt in the terminal. If the value is empty or not set, it can cause the terminal to display a blank screen.

Step 2: Check the Node.js Installation

Next, let's check if Node.js was installed correctly. You can do this by typing the following command:

node -v

This command will display the version of Node.js installed on your system. If Node.js is not installed correctly, it can cause problems with the terminal.

Step 3: Check the Angular Environment Setup

If Node.js is installed correctly, let's check if the Angular environment was set up correctly. You can do this by typing the following command:

ng --version

This command will display the version of Angular installed on your system. If the Angular environment was not set up correctly, it can also cause issues with the terminal.

Step 4: Reset the Terminal Configuration

If none of the above steps resolve the issue, let's try resetting the terminal configuration. You can do this by typing the following command:

reset

This command will reset the terminal configuration to its default settings.

Step 5: Reinstall Node.js and Angular

If none of the above steps resolve the issue, let's try reinstalling Node.js and Angular. You can do this by following these steps:

Uninstall Node.js: Type the following command to uninstall Node.js:
