 Python packages required by ESP-IDF are located in the ``$IDF_PATH/requirements.txt`` file. You can install them by running::
 
-    sudo pip install -r $IDF_PATH/requirements.txt
+    sudo python -m pip install -r $IDF_PATH/requirements.txt
 
 or you can use the following command for installing them into the user install directory on systems where you don't have administrator rights::
 
-    pip install --user -r $IDF_PATH/requirements.txt
+    python -m pip install --user -r $IDF_PATH/requirements.txt
+
+.. note::
+
+    Please invoke that version of the Python interpreter which you will be using with ESP-IDF. The version of the
+    interpreter can be checked by running command ``python --version`` and depending on the result, you might want to
+    use ``python2``, ``python2.7`` or similar instead of ``python``, e.g.::
+
+        sudo python2.7 -m pip install -r $IDF_PATH/requirements.txt
