Lightning Web Components


 Lightning Web Component series: Common Errors While Installing VS Code

In this article, we will discuss the common errors that are encountered while installing VS Code. There are two steps involved before starting with your first Lightning Web component.

  1. Installing CLI
  2. Download Salesforce CLI using the appropriate link for your operating system:

Operating System

Link to Installer


Windows 32-bit

Windows 64-bit

Debian/Ubuntu 64

Download the archive from one of the URLs in the manifest, extract the archive, then run the ./install script.

Debian/Ubuntu x86

Download the archive from one of the URLs in the manifest, extract the archive, then run the ./install script.

  1. Run the Installer and open a command line prompt, such as cmd on windows or Linux or Terminal on macOS.
  2. Run sfdx plugins –core in command line prompt to confirm the installation.

2. Installing VS Code

You could use the link below to install VS Code in your machine.

 There is an exclusive trailhead with the Installation steps.

 Common Errors:

  1. Error: Incompatible Java version(Java 8 or more recent is required to run. Please

download and install a recent JDK).

Install latest version of jdk by checking any of the below links

  1. Error: Salesforce CLI is Not Installed

This is one of the most common errors that most of the user encounters. This could happen because of a couple of reasons.

  1. You might have missed the installation of Salesforce CLI. If so go back and install Salesforce CLI. You can refer the first section of the article for the steps
  2. You might have installed 32-bit version of Salesforce CLI and trying to install a 64-bit version of VS Code. Uninstall 32-bit version of Salesforce CLI and install a 64-bit version of Salesforce CLI. Once the 64-bit Salesforce CLI is installed then go ahead and install a 64-bit version of VS Code.
  3. If you still see the issue after doing the first two steps then check the Path to make sure “Salesforce CLI” is setup in the path.

Go to Window Search–> Type Environment variables–> Open

3. Error:  deploying or retrieving source

The file or directory that you tried to deploy or retrieve isn’t in a package directory that’s specified in your sfdx-project.json file. Add this location to your “packageDirectories” value, or deploy or retrieve a different file or directory. For details about sfdx-project.json

This type of error occurs when we do not specify a folder name when we are creating a new project using vscode. To resolve this error create a new folder and use the same folder in VS Code.

4. Error: Unable to load the schema from ‘’: unable to verify the first certificate.

In order to resolve this error go to your project folder in vs code and select config and replace project-scratch-def.json file with the below code from Github
