There is cyrcle.yml:

```
deployment:
  development:
    branch:
      - develop
    commands:
      - ${DEPLOY_STAGING_COMMAND}

```

And `DEPLOY_STAGING_COMMAND` is defined in Environment variables with value:

```
ssh ubuntu@54.165.245.171 "cd /home/ubuntu/crab && git pull && composer install --prefer-dist --no-dev"

```

Result always fails with error:

```
Warning: Permanently added '54.165.245.171' (ECDSA) to the list of known hosts.
bash: cd /home/ubuntu/crab && git pull && composer install --prefer-dist --no-dev: No such file or directory
${DEPLOY_STAGING_COMMAND} returned exit code 127
Action failed: ${DEPLOY_STAGING_COMMAND}

```

But if I replace ${DEPLOY\_STAGING\_COMMAND} with original value in cyrcle.yml, like this:

```
deployment:
  development:
    branch:
      - develop
    commands:
      - ssh ubuntu@54.165.245.171 "cd /home/ubuntu/crab && git pull && composer install --prefer-dist --no-dev"

```

It works fine! Also it works if I replace some string with variables:

```
deployment:
  development:
    branch:
      - develop
    commands:
      - ssh ${DEPLOY_USER}@${DEPLOY_SERVER} "cd ${DEPLOY_PATH} && git pull && composer install --prefer-dist --no-dev"

```

But, in my case, I need to customize deploy command from CircleCI project settings GUI.

Is there anybody who can explain why CircleCI fails with `No such file or directory` error when binding deploy command to `${DEPLOY_STAGING_COMMAND}` variable?

Thank you!

Is this done via the Environment Variables page on the website? Or somewhere else?

And there is solution:

```auto
deployment:
  development:
    branch:
      - develop
    commands:
      - eval ${DEPLOY_STAGING_COMMAND}

```
