pip-compile error: AttributeError: 'ParsedRequirement' object has no attribute 'editable'

Question

I'm trying to use pip-compile to build my requirements.txt file and I get the following error.

Traceback (most recent call last):
  File "/Users/foobar/.pyenv/versions/3.7.0/bin/pip-compile", line 11, in <module>

    if ireq.editable:
AttributeError: 'ParsedRequirement' object has no attribute 'editable'

• pip==21.2.4
• pip-tools==6.2.0

I tried downgrading pip and pip-tools according to the pip-tools pypi website together but I can't seem to overcome this error. If anyone has suggestions, they'd be much appreciated.

Answer 1

The error comes from pip-tools trying to access the editable attribute on the class ParsedRequirement, whereas the correct attribute name on that class is is_editable. With previous versions of pip, the object at ireq were of type InstallRequirement, which does have the attribute editable.

Try pip==20.0.2; that seems to be the last version that returned InstallRequirement instead of ParsedRequirement from the relevant method (parse_requirements).
