IOError: [Errno 13] Permission denied

Question

I have this piece of code to create a .json file to store python data. When i run it in my server i get this error:

IOError: [Errno 13] Permission denied: 'juliodantas2015.json' at line with open(output_file, 'wb') as fp:

Python code:

fich_input='juliodantas2015.txt'
output_file= fich_input.strip('.txt')+'.json'
import json
with open(output_file, 'wb') as fp:
    json.dump('yes', fp)

In command line i typed chmod 777 *.py but still not working. How can i fix this ?

Answer 1

I had a similar problem. I was attempting to have a file written every time a user visits a website.

The problem ended up being twofold.

1: the permissions were not set correctly

2: I attempted to use
f = open(r"newfile.txt","w+") (Wrong)

After changing the file to 777 (all users can read/write)
chmod 777 /var/www/path/to/file
and changing the path to an absolute path, my problem was solved
f = open(r"/var/www/path/to/file/newfile.txt","w+") (Right)

Answer 2

IOError: [Errno 13] Permission denied: 'juliodantas2015.json'

tells you everything you need to know: though you successfully made your python program executable with your chmod , python can't open that juliodantas2015.json' file for writing. You probably don't have the rights to create new files in the folder you're currently in.

I have a really stupid use case for why I got this error. Originally I was printing my data > file.txt

Then I changed my mind, and decided to use open("file.txt", "w") instead. But when I called python, I left > file.txt .....
