Poetry: python 2.7 poetry-add failure
- [x] I am on the latest Poetry version.
- [x] I have searched the issues of this repo and believe that this is not a duplicate.
- [x] If an exception occurs when executing a command, I executed it again in debug mode (
-vvvoption).

OK, so how about this (continued in python repl as above):

>>> subprocess.check_output(cmd)

I think the root problem is poetry vendorizes packages which aren't python-only. This causes pre-built code to not run properly on machines which otherwise would have installed/built it themselves.
so in short you can't reliably count on the curl installation method to work
