From my experience this is suspect, the path to your bench is not correct - the problem may be with your install? bench.utils.CommandFailedError: npm install

Another suggestion - with your listings, include the command prompt, so your audience will know the user account for example ‘frappe’ and the directory you run a command from for example ‘frappe-bench’

frappe@ubuntu1804lts:~/frappe-bench$ which bench
/home/frappe/.local/bin/bench

Also perhaps point to the ‘official’ install notes you used to perform the install.

Here is my command prompt result -

I followed many forum threads and was lucky to get it solved. Thanks all for the help. Just for other’s help. The hint above that the bench path is incorrect was the first step in identifying the problem. I then deleted all the wrong directories.

I then followed Bench update fails: /bin/sh: 1: ./env/bin/pip: not found

Then I found nginx was not working and fixed it’s issues. FInally a reboot did the job.
