Good morning, I am trying to use caravel_user_project. I followed the steps in the tutorial, but I am receiving this error. I can't even run the basic example. How can I resolve this?

You are missing a dependency https://pypi.org/project/volare/

yheap. Install it.

Sorry, I didn’t understand. What should I do? Do I need to run the command 
make setup
again?
ε
yes. Google it .
l
Google what ?
I don't understand. 1. I've cloned the repository. I ran the command 
make setup
. 2. I ran the command 
make user_project_example
and received that error. 3. I installed Volare. 4. I ran the command 
make user_project_example
again and received the same error. What should I do?

Try following
Copy code
export PDK=sky130A
make pdk-with-volare
Then try hardening design
make user_proj_example
should be executed inside 
caravel_user_project
directory not from 
openlane
directory. Here 
make
execution different
l
Still get the same error
ε
do not use sudo
Copy code
sudo apt-get update
sudo apt-get install python3 python3-pip xz-utils
l
without sudo
ε
Copy code
python3 -m pip install --upgrade --no-cache-dir volare
Copy code
To verify it works
volare --version

Check paths
echo $PATH

run 
make setup
again and see all installation completes or fails some where
ε
pragraph 4.2
you need to set the path for caravel executables
l
I had already done that. But it still gave the same error. Another question: how can I free up the occupied space? It seems to me that simply deleting the folder is not enough.
ε
reinstall
follow the previous attached guide
shift + del = purge
check trash
l
Sorry, be precise. I want to delete everything done so far, but it seems that deleting the folder alone is not enough. How can I clean everything up?
