 UglifyJS is available as a `Node.js`_ module. First, you need to `install Node.js`_
 and then, decide the installation method: global or local.
 
+.. caution::
+
+    Some Linux distributions rename the Node.js binary from ``node`` to ``nodejs``.
+    This may result in errors like *"/usr/bin/env: node: No such file or 
+    directory"*``. You can solve this problem with a symlink:
+
+    .. code-block:: terminal
