UnicodeDecodeError: 'ascii' codec can't decode byte 0xc3 in position 19: ordinal not in range(128)
ubuntu@ip-172-31-19-194:~/frappe-bench$

I think this exact error has appeared before. I cant remember the details but please search in the forum’s and / or issues and you may find some helpful information

I found it some posts about this, but not helped me…

Have you any custom apps?

Yes, I have

Does it involve language translation?

File “/usr/lib/python2.7/compileall.py”, line 41, in compile_dir
names.sort()
UnicodeDecodeError: ‘ascii’ codec can’t decode byte 0xc3 in position 19: ordinal not in range(128)

Can you give me an example about this?
Are you talking about __ on javascript?

My guess is the Python compiler does not ‘like’ your custom app code.

This page outlines how you can go to the custom app directory and run the compiler to identify the offending file https://docs.python.org/2/library/compileall.html

This library don’t works for me, after run compile command on app/ folder, this does not return any error…

ok these help explain your problem - a filename that Python runs afoul on…

https://stackoverflow.com/questions/21772271/unicodedecodeerror-when-performing-os-walk

A console session like this example here can help you identify the problem filename -

frappe@erpnext:~/frappe-bench$ bench console
Python 2.7.6 (default, Jun 22 2015, 18:00:18)

I’ll uninstall and remove all custom apps on my dev machine and try run bench update again

So then you have identified and confirmed the problem source is indeed a filename?

So is this the problem character

u’ñ’
u’\xf1’

u’ñ’.encode(‘utf8’)
‘\xc3\xb1’

u’ñ’.encode(‘utf8’).encode(‘utf8’)
Traceback (most recent call last):

No, I try uninstalling custom apps but not works at all…

I think the problem is the erpnext app, just there has this types of languages…

Uninstalled all custom apps and the issue continues… I think this is not a file name

“I think this is not a file name”

You have checked and can you confirm that? Your stack trace suggests otherwise

File “/usr/lib/python2.7/compileall.py”, line 41, in compile_dir
names.sort()

I’ve checked all of custom apps, folder by folder
There’s no way to see what’s the entire name with the compile?

“there’s no way to see what’s the entire name with the compile?”

Maybe try ‘ls -R apps/your_custom_app’ to view the filenames?

No, see the file name with problem hehehe

I’ll check again, thank’s in advance for now @clarkej :smiley:
