Install Amazon ParallelCluster in a virtual environment (recommended)

To install Amazon ParallelCluster in a virtual environment

1. If virtualenv isn't installed, install virtualenv using pip3. If python3 -m virtualenv help displays help information, go to step 2.

   $ python3 -m pip install --upgrade pip
   $ python3 -m pip install --user --upgrade virtualenv

   Run exit to leave the current terminal window and open a new terminal window to pick up changes to the environment.

2. Create a virtual environment and name it.

   $ python3 -m virtualenv ~/apc-ve

   Alternatively, you can use the -p option to specify a specific version of Python.

   $ python3  -m virtualenv -p $(which python3) ~/apc-ve

3. Activate your new virtual environment.

   $ source ~/apc-ve/bin/activate

4. Install Amazon ParallelCluster into your virtual environment.

   (apc-ve)~$ python3 -m pip install --upgrade "aws-parallelcluster"

5. Install Node Version Manager and the latest Long-Term Support (LTS) Node.js version. Amazon Cloud Development Kit (Amazon CDK) (Amazon CDK) requires Node.js for CloudFormation for template generation.

   Note

   If your Node.js installation isn't working on your platform, you can install an LTS version prior to the latest LTS version. For more information, see the Node.js release schedule and the Amazon CDK prerequisites.

   Example Node.js installation command:

   $  nvm install --lts=Hydrogen

   $ curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.38.0/install.sh | bash
   $ chmod ug+x ~/.nvm/nvm.sh
   $ source ~/.nvm/nvm.sh
   $ nvm install --lts
   $ node --version

6. Verify that Amazon ParallelCluster is installed correctly.

   $ pcluster version
   {
     "version": "3.7.0"
   }
