Problems installing on windows

[sblunt]

I've tried installing ptemcee on three windows computers, and I get the same error on all of them:

Traceback (most recent call last): File "<string>", line 1, in <module> File "C:\Users\Rajeev\AppData\Local\Temp\pip-install-3exhreqn\ptemcee\setup.py", line 39, in <module> long_description=read('README.rst'), File "C:\Users\Rajeev\AppData\Local\Temp\pip-install-3exhreqn\ptemcee\setup.py", line 20, in read return f.read() File "C:\Users\Rajeev\Miniconda3\lib\encodings\cp1252.py", line 23, in decode return codecs.charmap_decode(input,self.errors,decoding_table)[0] UnicodeDecodeError: 'charmap' codec can't decode byte 0x90 in position 449: character maps to <undefined>

As far as I can tell, there's at least one non-ASCII character in the README that's preventing install. Cloning the repo and removing the README fixes the issue.

Hi,

I assume you're using Python version 3. In which case, I think the problem is in line 18 in setup.py:
kwargs = {'encoding': 'utf-8'} if major > 3 else {}

The problem is it only sets the encoding if the major version is > 3, whereas it needs to be >= 3. So change the line to the following, and it should work.
kwargs = {'encoding': 'utf-8'} if major >= 3 else {}

:)

Yes, I've gotten it to work on my own machines, but since this package is a dependency for my own package, I would love if users could just pip install it themselves without complication.

Hello, given ptemcee is a requirement of other pip packages, would you please update it on PyPi as well? I got recently the same error, because the pypi setup.py file still have the same typo.

Trying to install via ligo.skymap and receiving the following errors:

File string, line 1, in module
File "C:\Users\xxxxx\AppData\Local\Temp\pip-install-xvptqw8g\ptemcee\setup.py", line 39, in
long_description=read('README.rst'),
File "C:\Users\xxxxx\AppData\Local\Temp\pip-install-xvptqw8g\ptemcee\setup.py", line 20, in read
return f.read()
File "c:\users\xxxxx\anaconda3\lib\encodings\cp1252.py", line 23, in decode
return codecs.charmap_decode(input,self.errors,decoding_table)[0]

Seems like a similar issue in setup.py as above?

When attempting to install via pip3 on Windows 10:

This appears to be the same issue as elsewhere in this thread. Are there existing workarounds?
