The following command creates a new Bash shell with an empty environment, loads the workspace's setup.bash, and then executes roslaunch. It works.

$ env -i /bin/bash -c "cd /home/user/myproject; . ./devel/setup.bash; roslaunch myproject myproject.launch"

But if we use sh instead of Bash, it does not:

$ env -i /bin/sh -c "cd /home/user/myproject; . ./devel/setup.sh; roslaunch myproject myproject.launch"
RLException: [myproject.launch] is neither a launch file in package [myproject] nor is [myproject] a launch file name

If we diff the two environments set up by setup.sh and setup.bash, we have several differences, including this key one:

-ROS_PACKAGE_PATH=/home/user/myproject/build/catkin_tools_prebuild:/opt/ros/melodic/share
+ROS_PACKAGE_PATH=/home/user/myproject/src/myproject:/opt/ros/melodic/share

Yet even after cleaning and rebuilding from scratch, this issue persists. What is causing it?


This is Ubuntu 18.04 with ROS Melodic on arm64, and
