I cloned grumpy and run method 1, but it cause error

➜  grumpy git:(master) echo "print 'hello, world'" | make run
build/src/grumpy/lib/__builtin__/module.go:1: syntax error: package statement must be first
make: *** [build/pkg/darwin_amd64/grumpy/lib/__builtin__.a] Error 1

Can you paste the result of:

$ head build/src/grumpy/lib/__builtin__/module.go

That's very odd. It looks like some random program has generated the module.go file, not grumpc, the Grumpy compiler. There must be something unexpected in your environment. I would suggest rm -rf build and then make run again.

Now I met error like it

import is screen shot command by imagemagick, looks like your shell doing something different.

Try git checkout 3adaa1a949115466e9ea204e4173e79ba8059870 before latest Makefile update. and try to make clean and make, to make sure that is not the case

Now it works! What's the problem?

➜  grumpy git:(master) git checkout 3adaa1a
Note: checking out '3adaa1a'.

You are in 'detached HEAD' state. You can look around, make experimental
changes and commit them, and you can discard any commits you make in this
state without impacting any branches by performing another checkout.

If you want to create a new branch to retain commits you create, you may
do so (now or later) by using -b with the checkout command again. Example:

  git checkout -b <new-branch-name>

HEAD is now at 3adaa1a... make itertools.chain be a class and from_iterable a classmethod of chain
➜  grumpy git:(3adaa1a) rm -rf build
➜  grumpy git:(3adaa1a) make clean
➜  grumpy git:(3adaa1a) echo "print 'hello, world'" | make run
hello, world

@trotterdylan, Looks like there is some issue with recent Makefile changes. I can't think of which one though.

@growingdever , what is your python -V, python2 -V, env python -V?

[alanjds]

Comment by toughrogrammer Friday Jan 13, 2017 at 04:33 GMT

I'm using pyenv. Global python, python2 version is 2.7.12

@growingdever Could you paste the output of: $ head build/bin/grumpc

Looks like shebang is lost, so may be another sed issue

What you get when you type /usr/bin/env python -V or /usr/bin/env python?

[alanjds]

Comment by trotterdylan Friday Jan 13, 2017 at 04:47 GMT

@growingdever I meant what is $ head build/bin/grumpc at HEAD, when things are broken.

Thanks for your help debugging this.

@S-YOU I think you're right that the shebang line is gone and it's being interpreted as a sh script.

[alanjds]

Comment by S-YOU Friday Jan 13, 2017 at 05:00 GMT

@trotterdylan,

His head output show there is still #!/usr/bin/env python and /usr/bin/env python -V correct though, I am not sure it something different under pyenv, virtualenv.

[alanjds]

Comment by trotterdylan Friday Jan 13, 2017 at 05:01 GMT

@S-YOU But I think that shebang line is from 3adaa1a, before the Makefile change.

[alanjds]

Comment by S-YOU Friday Jan 13, 2017 at 05:02 GMT

---

I see, does make run change those shebang on the fly?

[alanjds]

Comment by trotterdylan Friday Jan 13, 2017 at 05:08 GMT

---

make run depends on make all, which moves tools/grumpc -> build/bin/grumpc and changes the shebang.

[alanjds]

Comment by S-YOU Friday Jan 13, 2017 at 05:11 GMT

---

@growingdever , I think we need head build/bin/grumpc and /usr/bin/env python -V from master, not that commit.

Please do git checkout master and make clean, make, head build/bin/grumpc, /usr/bin/env python -V

how about ls -la ~/.pyenv/shims/python* and ~/.pyenv/shims/python -V

looks like those python binary are shell scripts 414B so, this is pyenv specific

@trotterdylan, may be instead of replacing the whole shebang, but just change python part to basename $(PYTHON_BIN)?

Comment by toughrogrammer Friday Jan 13, 2017 at 05:36 GMT

Yes. It's shell script.

➜  grumpy git:(master) cat ~/.pyenv/shims/python
#!/usr/bin/env bash
set -e
[ -n "$PYENV_DEBUG" ] && set -x

program="${0##*/}"
if [[ "$program" = "python"* ]]; then
  for arg; do
    case "$arg" in
    -c* | -- ) break ;;
    */* )
      if [ -f "$arg" ]; then
        export PYENV_FILE_ARG="$arg"
        break
      fi
      ;;
    esac
  done
fi

export PYENV_ROOT="/Users/juhongjung/.pyenv"
exec "/Users/juhongjung/.pyenv/libexec/pyenv" exec "$program" "$@"

If you have a system install of Python you might be able to work around this by specifying it as the PYTHON variable to make. First make clean, then make PYTHON=/usr/bin/python or make PYTHON=/usr/bin/python run

Right. make works well with python path option.

Thanks for reporting this. I think I'll need to try pyenv to reproduce this issue so I may not get around to it right away.
