Pastebin pbwrap 在 python 3.9.5 上有 AttributeError: __enter__ with io.open()

Question

The pastebin package pbwrap from pypi always worked properly for me before but it doesn't work with python 3.9.5. It's not able to read the input file and gives the error below.

from pbwrap import Pastebin   # https://pypi.org/project/pbwrap/

api_dev_key = r'your key'
username = r'your login'
password = r'your password'
pb = Pastebin(api_dev_key)
user_id = pb.authenticate(username, password)

### Pasting text to pastebin works as expected.
paste_url = pb.create_paste('this is a test', api_paste_private=1, api_paste_name='test')
print(paste_url)

### Make a simple text file to upload to pastebin
with open('test.txt', 'w') as f:
    f.write('This is line #1\n')
    f.write('This is line #2\n')

### When uploading a file to pastebin, an I/O error is returned from io.open() called from pbwrap
paste_url = pb.create_paste_from_file('test.txt', api_paste_private=1, api_paste_name='test')
print(paste_url)

### pbwrap.py", line 180, in create_paste_from_file
###     with io.open(
### AttributeError: __enter__

Answer 1

This turned out to be a bug that was introduced in 2020 when the module was upgraded to use utf-8. I have forked the pbwrap source code and submitted a fix. The file read needed to be moved outside the context of the with io.open.

Answer 2

you can try by re-installing the package by pip command it will work for you
