ssh remote project interpreter error: bash: env: command not found

I use pycharm 2017.2.3 and deploy my files to another device with Python 2.7 installed. For this device I set up a ssh remote interpreter. On the device is a directory .pycharm_helpers. The Project:Interpreter settings page says: Python packaging tools not found. Install packaging tools. Installing this I get the following error:

Executed commands:

./.pycharm_helpers/packaging_tools.py untar

./.pycharm_helpers.setuptools-28.8.0.tar.gz

Error occured: Non-zero exit code (127)

bash: env: command not found
