Deploy Alexa skill on amazon using circle ci

Serverless Framework
1

I have created a Alexa skill and deployed from local system to the amazon. It is working fine. Now I am trying to use circle ci to setup the alexa skill. I have used ask cli to deploy the skill, It is throwing error.

- run:
         name: 'npm install serverless'
         command: |
         sudo npm install --unsafe-perm -g ask-cli
- run:
          name: 'serverless deploy'
          command: |
             serverless deploy --region us-west-2 --stage dev
      - run:
          name: 'echo $AWS_ACCOUNT_ID'
          command: echo $AWS_ACCOUNT_ID
      - run:
          name: 'echo $AWS_ACCESS_KEY_ID'
          command: echo $AWS_ACCESS_KEY_ID
      - run:
          name: 'echo $AWS_SECRET_ACCESS_KEY'
          command: echo $AWS_SECRET_ACCESS_KEY
      - run:
          name: 'echo $AWS_DEFAULT_REGION'
          command: echo $AWS_DEFAULT_REGION
      - run:
          name: 'echo $ASK_CLI_CONFIG'
          command: echo $ASK_CLI_CONFIG
      - run:
          name: Setup Environment Variables
          command: |
            echo 'LOCAL="en-US"' >> $BASH_ENV
      - run:
          name: 'skill deploy'
          command: |
            mkdir -p ~/.ask
            echo 'ASK_CLI_CONFIG:$ASK_CLI_CONFIG' > ~/.ask/cli_config
            ask deploy --target skill --debug

I am getting error Invalid json: /home/circleci/.ask/cli_config Exited with code 1

Help will be most appreciated.

Please let me know how to fix it.

when i try only sudo npm install -g ask-cli it is not installing the ask cli, it is throwing error also.
