sh: 1: tailwindcss: Permission denied / tailwindcss

I have a problem while run the build command from Tailwindcss (i am using tailwindcss CLI):

npx tailwindcss -i ./src/input.css -o ./public/css/output.css --watch 

While running this command, it puts an output like the following:

sh: 1: tailwindcss: Permission denied 

I have already reinstalled nodejs and npm. The versions are: nodejs:v18.2.0, npm:8.11.0

The folder permissions are the following:

jonas@jonas-ubuntu ~/D/G/WOWA-BAU-NEU (main)> ls -la insgesamt 100 drwxrwxr-x 8 jonas jonas 4096 Mai 23 21:47 ./ drwxrwxr-x 3 jonas jonas 4096 Mai 25 22:53 ../ -rw-rw-r-- 1 jonas jonas 11701 Mai 23 21:47 build.css -rw-rw-r-- 1 jonas jonas 0 Mai 23 21:47 file drwxrwxr-x 8 jonas jonas 4096 Mai 31 14:59 .git/ drwxrwxr-x 59 jonas jonas 4096 Mai 23 21:47 node_modules/ drwxrwxr-x 2 jonas jonas 4096 Mai 23 21:47 old/ -rw-rw-r-- 1 jonas jonas 60 Mai 23 21:47 package.json -rw-rw-r-- 1 jonas jonas 45723 Mai 23 21:47 package-lock.json drwxrwxr-x 5 jonas jonas 4096 Mai 30 13:51 public/ drwxrwxr-x 2 jonas jonas 4096 Mai 23 21:47 src/ -rw-rw-r-- 1 jonas jonas 108 Mai 23 21:47 tailwind.config.js drwxrwxr-x 2 jonas jonas 4096 Mai 23 21:47 .vscode/ 

for me they look correct to read, write and execute.
