Windows

The version number is not displayed even after installing Python on Windows

Even if you install a Python version supported by OpenRTM-aist and add the Python path at that time, the version number may not be displayed when you check it from the Command Prompt.

 >python --version
 Python

Cause:

  • A version downloaded from the Microsoft Store or similar may already be installed
  • Check the installation location with the where python command 
     >where python

Solution:

  • Check Python’s app execution aliases, and if they are turned on, turn them off and restart Windows
  • In Windows Settings → Apps & features → App execution aliases, turn off “pytnon.exe” and “python3.exe”

After restarting, confirm that the Python version number is displayed in the Command Prompt. For the procedure for adding the path when installing Python, see the explanation on the following page.

OpenRTM-aist 1.1.2 was installed on Windows 10, but it was not added to PATH

  • If the PATH setting is long, it may be truncated due to the length limit.

Solution: Restart the PC after installation.

The omniORB PATH setting is not expanded on Windows 10

When checking the set command on Windows 10, the variable part %OMNI_ROOT% of the omniORB PATH setting was not expanded.

Cause:

  • This may be a phenomenon that occurs only on Windows 10.
  • The PATH may not have been expanded.

Solution: Restart the PC after installation.

A download error is displayed during automatic package installation

The automatic installer included with OpenRTM-aist checks for the presence and version of packages, and if an appropriate package is not installed, it downloads and processes each package from its download site. For this reason, when installing with the automatic installer, be sure to connect the computer to the Internet.~ If a download error occurs even though the network connection is normal, the download may have failed due to line congestion or similar reasons, or the file location or name may have changed on the download site side. In the former case, try running the automatic installer again at a different time of day. In the latter case, find the relevant package and download and install it manually, or correct the download source address in the automatic installer and then start it again.~
