***********************************
1. Locating virtualenv installation

ERROR: Could not find and "virtualenv" installed. Ensurevirtualenv is installed and that it is in PATH before executingthis script.

2. Creating exclusive virtualenv for EBCLI

/bin/sh: /usr/local/bin/virtualenv: /usr/bin/python: bad interpreter: No such file or directory

```

Start by reproducing the command from the issue with scripts/ebcli_installer.py and inspect how it locates virtualenv and creates the EBCLI environment. Check the /usr/local/bin/virtualenv interpreter reference and the installer’s handling of that failure. Done means the reported installation path either completes successfully or gives a clear, actionable error for this environment.
