Cannot complete installation of ROS2 on Windows10 64bit

edit

While completing the installation instructions on:

https://index.ros.org/doc/ros2/Instal...

I was unable to complete the last part:

Set up the ROS 2 environment¶

Start a command shell and source the ROS 2 setup file to set up the workspace:

call C:\dev\ros2\local_setup.bat

After running the command, I get:

";C:\Program Files\JetBrains\PyCharm Community Edition 2019.1.3\bin;C:\Users\Michael\AppData\Local\Microsoft\WindowsApps;C:\Users\Michael\AppData\Local\Programs\Microsoft VS Code\bin" was unexpected at this time.

any help appreciated
