Error installing frappe: Permission denied: 'yarn' on CentOS 7-CodePudding

I am trying to install ERPNext on a VPS with CentOS 7 and Plesk Pre-installed.

At the step where I need to use this command:

 bench init --frappe-branch version-12 frappe-bench

I get this error:

[frappe@musing-carver npm]$  bench init --frappe-branch version-12 frappe-bench
$ /usr/local/bin/virtualenv --quiet env -p python3
$ /usr/lib/node_modules/npm/frappe-bench/env/bin/python -m pip install --quiet --upgrade pip
Getting frappe

ERROR: There was a problem while creating frappe-bench

I was following this tutorial step by step: How To Install ERPNext in CentOS / RHEL || Erpnext || TechHack Tamil

I have nodejs v10 instead of v14 or v16, ¿is this a problem?

Thank you in advance

CodePudding user response：

try to use sudo before execute the command

sudo  bench init --frappe-branch version-12 frappe-bench

let me know the result

CodePudding user response：

I have solved the problem.

I simply reinstalled yarn and now it is working.

sudo yum install yarn

I don't know exactly why it was failing before... any clarification will be welcome.
