Installation Error on Centos 7.4

Hi,

I’m encountering the following error while running the easy install script on a Centos server. Is this a bug?

Traceback (most recent call last):
  File "install.py", line 400, in <module>
    install_bench(args)
  File "install.py", line 104, in install_bench
    run_playbook('create_user.yml', extra_vars=extra_vars)
  File "install.py", line 333, in run_playbook
    success = subprocess.check_call(args, cwd=os.path.join(cwd, 'playbooks'))
  File "/usr/lib64/python2.7/subprocess.py", line 537, in check_call
    retcode = call(*popenargs, **kwargs)
  File "/usr/lib64/python2.7/subprocess.py", line 524, in call
    return Popen(*popenargs, **kwargs).wait()
  File "/usr/lib64/python2.7/subprocess.py", line 711, in __init__
    errread, errwrite)
  File "/usr/lib64/python2.7/subprocess.py", line 1327, in _execute_child
    raise child_exception
OSError: [Errno 2] No such file or directory

I need a workaround please

Thanks

I tried installing in Debian 9.4 a couple of minutes ago and got the same error.
Can someone check if it is occurring on Ubuntu as well?

I tried installing some of the prerequisites manually to see if that would solve the problem. Now I’m getting the error below

Traceback (most recent call last):
  File "install.py", line 400, in <module>
    install_bench(args)
  File "install.py", line 104, in install_bench
    run_playbook('create_user.yml', extra_vars=extra_vars)
  File "install.py", line 333, in run_playbook
    success = subprocess.check_call(args, cwd=os.path.join(cwd, 'playbooks'))
  File "/usr/lib64/python2.7/subprocess.py", line 537, in check_call
    retcode = call(*popenargs, **kwargs)
  File "/usr/lib64/python2.7/subprocess.py", line 524, in call
    return Popen(*popenargs, **kwargs).wait()

    errread, errwrite)
  File "/usr/lib64/python2.7/subprocess.py", line 1327, in _execute_child
    raise child_exception
OSError: [Errno 13] Permission denied

Seems to still be coming from the same source. I hope this can be looked into urgently

Thanks

I just tired a fresh install in Digital Ocean VPS on Ubuntu 16.04 64bit and I get the same error.

Need some urgent solution to this…

Working on the fix… It’s related to pip not being installed properly on the system python get-pip.py fails for pip 10 · Issue #5220 · pypa/pip · GitHub

Bench is fixed. However, problems still persist in frappe and erpnext. Have sent in PRs for the same. They should get merged in a short span of time

Hi @codingCoffee

Thanks a lot for responding quickly. After getting the first error, I suspected there was some issue with pip so I installed it manually. I also installed Node JS. After that I tried again and got the second error

Do your fixes take care of both errors?

Hope the PRs get merged asap

If you’re talking about production install using the easy install scripts, then yes, all errors are taken care of with my PRs. I’ve tested and ensured that.

However, if you’re talking about develop install using the easy install scripts, then I think some errors still persist there. And they are mostly unicode errors, python 2 - 3 fixes, which are yet to be made.

Hi @codingCoffee

Yes I’m referring to production using the easy install script

Thanks a lot

Hi @codingCoffee

Looks like the fixes have been merged now. Can you please confirm so we can try again?

Thanks

11

@wale yup they have been merged. Production install should work perfectly now. You can give it a try.

Hi @codingCoffee

Just tried again but got the error below :slightly_frowning_face:

Traceback (most recent call last):

Pls help fix

Thanks

@wale can you post the command you executed and the user who you executed it as.

Before posting the above comment, I was successfully able to get the easy install on a Cent OS 7 droplet.

14

Hi @codingCoffee

I used the following command:

python install.py --production --user frappe

I ran it as root user

15

@wale I just tried an install. It worked perfectly again. I’m unable to replicate the issue.

It feels like your user doesn’t have privileges to create a new user. But since you’re root I don’t see any reason for this error to pop up.
Can you try again on a fresh instance. Which VPS are you using?

16

Hi @codingCoffee

Thanks for your quick response. It’s a server hosted on-premise

As you rightly mentioned, I was a bit puzzled by the permission error since its a root user. Are there any particular dependencies that may also cause this kind of error or is it strictly related to the permission for creation of new user?

If that’s the only source of the error, maybe I could try creating the user directly? Please advise and let me know which user to create

Thanks

17

You could try by creating a password-less user named frappe.
But I don’t believe that’s the solution to the problem. The install script should work without it.
Try running:

$ yum check-update && yum update -y
$ yum install -y git wget curl
$ sudo python install.py --production --user frappe
18

Okay… will try this and revert

Thanks

Hi @codingCoffee

I’ve tried the commands but still the same results. Creating a user directly works without issues. Any other ideas please?

Thanks

In addition, I also tried to search for causes of similar errors and found that it seems to occur a lot when trying to execute a file that is not executable

I’m not sure if that gives any pointers but thought to mention it

Thanks
