Software Installation and Startup Questions

Post here if you have questions about installing software for and starting up a min-eVOLVER.

Wiki guide here.

Hi Nate, I’m having issues with the software installation and startup. Could I ask you a few questions? Really appreciate your help! Looking forward to your reply!

1. When I tried to build the virtual environments for dpu and server, I followed the instructions to use poetry to install the dependencies. I got messages back as the following:
   Installing the current project: dpu Error: The current project could not be installed: No file/folder found for package dpu If you do not want to install the current project use --no-root. If you want to use Poetry only for dependency management but not for packaging, you can disable package mode by setting package-mode = false in your pyproject.toml file. If you did intend to install the current project, you may need to set packages in your pyproject.toml file.
   I used “–no-root ” to go through this step. Is this right?

2. After the first step, I tried to run “python3 evolver.py” in the server-env. I got an error message saying that I haven’t installed the dependency such as yaml. I have to use “poetry run python3 evolver.py” to go through this step. I have to add “poetry run” before every command line to make it work. Is it normal?

3. After the second step, I can connect to the min-eVOLVER and get the port address and number. Then I tried to do the test for the hardware. When I connected to the min-eVOLVER with the computer and turned on the power, two pumps and the stirring system started to work. (Is this normal?) During the test, I felt that the min-eVOLVER was not responding. No change happened for the pump and stirring system. I also tried to use send_command to see whether I can control the system. It didn’t work. By any chance, do you have any idea about what might be wrong (software? Hardware?)? What should I do now? Will reuploading the Arduino code work?

4. Is there any way we can check whether PCB is assembled well?

1. “Error: The current project could not be installed: No file/folder found for package dpu”
   1. This seems like you are not inside of the dpu folder, so poetry is looking for the poetry.lock and poetry.toml files and not finding them.
   2. I would delete the dpu folder and start over from a fresh virtual environment etc, just to make sure nothing is messed up
   3. Make sure you navigate inside of the folder in your terminal window before running poetry install
   4. “I used “–no-root ” to go through this step. Is this right?” you shouldn’t have to do this
2. It seems likely you haven’t installed things properly using poetry, so you aren’t seeing the package be available.
   1. I’d follow the same procedure I describe above for the server to make sure you get a clean install
   2. “I have to add “poetry run” before every command line to make it work. Is it normal?” - nope!
3. The dpu / server are not installed properly, so it’s likely that you won’t see a correct response from the min-eVOLVER
4. PCB assembly is tested using test_hardware.py but you need to properly install the software first before it’ll work

Hope this fixes things! If it doesn’t please post screenshots of the installation process for the dpu and server

I’m attaching the screenshots from both env for your review.

It is working after we reloaded the arduino code. Thanks for help!
