Having exactly same issue.

minimal reproducible example of Pipfile:

[scripts]
hello_env_variable = "FOO='hello world' python -c 'import os; print(os.getenv(\"FOO\"))'"

and run it:

pipenv run hello_env_variable

And got error:

Error: the command FOO=hello world (from hello_env_variable) could not be found within PATH.

When I run same command last working version of pipenv I got correct output:
