environment variables in pipfile scripts are not recognized correctly

[Madoshakalaka]

When running scripts from pipfile. Unix style environment variables are wrongly recognized as commands.

Expected result

hello=world is recognized as setting an environment variable

Actual result

Error: the command hello=world (from generic-script) could not be found within PATH.

Steps to replicate

• have the following part in pipfile

  [scripts]
  generic-script = 'hello=world python --version'
  

• $ pipenv run generic-script

[Madoshakalaka]

fyi: npm scripts in package.json handles this correctly

[Madoshakalaka]

a workaround is to use $ env hello=world <commands> on unix systems.

What about multiple environment arguments?

Hello everyone,
I am trying to contribute to the project trying to solve this issue.

I made a first hackish version that fixes the error of the issue.

Something that is missing, is defining which use cases this feature should cover.
Some examples:

• do we want to solve variables into the command? ${MYVAR} or $MY_VAR
• do we want to allow the execution of multiple commands if separated by semicolon? echo "hello"; python --version
• do we want to allow multiple command execution with | or && or || operators?

I think that the purpose of this feature was to give an easy tool for a developer to run local script to do tests.

I want to use something like below:

[scripts]
docker_build = "docker build --build-arg PYPI_CREDS=$env:PYPI_CREDS -t myimage:latest ."

Whereas PYPI_CREDS has already been defined and loaded by pipenv from .env file.
I am using windows OS.

Now, it is not able to resolve the env variable passed in docker_build script.

Any solution for this?

Okay I got a solution, I needed to use cmd.exe format of accessing the env variable, like below:

[scripts]
docker_build = "docker build --build-arg PYPI_CREDS=%PYPI_CREDS% -t myimage:latest ."
