I’m having trouble installing Node.js version 20 in an AWS CodeBuild environment. Can anyone provide guidance on how to achieve this?

I’m currently stuck trying to install Node.js version 20 in my AWS CodeBuild environment, and I’m hoping someone here can lend a hand. I thought this would be straightforward, but I’m running into some issues that I’m not sure how to tackle.

Here’s what I’ve been trying to do: I set up a build spec file (buildspec.yml) and specified the Node.js version in the prebuild phase, but for some reason, CodeBuild keeps pulling an older version of Node.js. I know that AWS offers Node.js environments, so I figured that updating to the latest version wouldn’t be too much of a hassle. My initial thought was to use the standard Node.js image provided by AWS, but since I need version 20 specifically, I’m not sure how to force it to use that version.

I’ve looked into using a custom Docker image, but that just adds another layer of complexity, and I’m not sure if I want to go down that route just yet. Has anyone found a way to install a specific version of Node.js in CodeBuild without going the Docker route?

I also tried using nvm (Node Version Manager) to install it during the build, but it seemed to cause issues with other dependencies in my environment. The logs are pretty cryptic, and I’m not sure if it’s related to the way nvm was loaded or if there are issues with the overall build image.

If anyone has successfully managed to get Node.js version 20 installed in their AWS CodeBuild environment, could you share your buildspec.yml configuration, any crucial commands you used, or tips on what worked for you? I’d love to hear about any pitfalls you encountered, too, so I can avoid making the same mistakes. Your help would seriously speed things up for me, and I’m sure others might find this info useful too! Thanks!

    1. To install Node.js version 20 in your AWS CodeBuild environment, you can indeed utilize the buildspec.yml file to configure your build. One effective approach involves using the nvm (Node Version Manager) to install the desired version. However, it requires careful handling to prevent any conflicts with dependencies. Here is a sample configuration you can use in your buildspec.yml:

      version: 0.2
phases:
  pre_build:
    commands:
      - curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.39.5/install.sh | bash
      - export NVM_DIR="$HOME/.nvm"
      - [ -s "$NVM_DIR/nvm.sh" ] && \. "$NVM_DIR/nvm.sh"
      - nvm install 20
      - nvm use 20
  build:
    commands:
      - node -v
      - npm -v

      In the example above, the pre_build phase includes commands to install nvm and then use it to install Node.js version 20. Make sure that your environment has access to the internet for this to work. Additionally, pay attention to the execution order of commands to ensure that nvm is correctly sourced before attempting to use it. If you’re still encountering issues, consider checking the build logs for errors, as they can provide insights into what’s going wrong. Another alternative could be to use the AWS CodeBuild custom image that has Node.js 20 pre-installed, which might simplify the process and mitigate potential conflicts.



    2. How to Install Node.js Version 20 in AWS CodeBuild

      Hey there! I totally relate to what you’re going through. Installing a specific version of Node.js in AWS CodeBuild can be a bit tricky. Here’s a simple way to get Node.js version 20 without fussing over Docker images!

      Using NVM in Buildspec

      Since you’re trying to use nvm, this approach can work! Here’s a sample buildspec.yml you can try:

          version: 0.2

    phases:
      pre_build:
        commands:
          # Installing nvm
          - curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.39.5/install.sh | bash
          - source ~/.nvm/nvm.sh
          # Install Node.js version 20
          - nvm install 20
          - nvm use 20
          - node -v # to check if the correct version is being used
      build:
        commands:
          - echo "Build started on `date`"
          - npm install
          - npm run build

      Tips

      • Make sure you’re sourcing nvm properly. If it’s not loaded, the commands won’t work.
      • Check the build logs for any errors related to nvm. Sometimes it’s due to the shell environment.
      • If you end up running into issues with other dependencies, try to isolate the problem by commenting out commands.

      Alternative: Custom Docker Image

      If nvm still gives you a headache, consider creating a custom Docker image with Node.js version 20 pre-installed. I know it sounds complex, but it can save you a lot of trouble in the long run!

      I hope this helps! Good luck with your CodeBuild setup! 😊
