Environment

Release:
Component: ACSAAS

Cause

There are two known causes for this issue

 

1. Invalid setting

This can be caused by having a GEM_COMMAND environment variable that is set to the wrong location.
In the error message, it is observed that the Ruby bin directory is Ruby22-x64 but install_gems is looking in Ruby226 for the gem command.

Please note that the documentation contains example GEM_COMMAND variables which may not be applicable to your environment.

 

2. Referencing a location that contains a space in the path

If Ruby is installed under a folder that contains a space, such as the Program Files folder, it can cause issues when our scripts attempt to reference gem in that location.

 

Resolution

Follow the resolution below that pertains to your identified cause above.

1. Invalid Setting

Update the GEM_COMMAND environment variable to reflect your actual installation directory.  This is the directory you would have chosen when you installed Ruby as shown in the image below:

In the error message above, Ruby is installed in C:\Ruby22-x64 so GEM_COMMAND should be set to C:\Ruby22-x64\bin\gem as shown in the image below:

 

2. Referencing a location that contains a space in the path

If your Ruby interpreter has been installed under a folder that contains a space in the folder name, it will be necessary to include quotes around the full path of the GEM_COMMAND location as shown in the screenshot below:
