Could not compile on 16.04.5 LTS Xenial Xerus (Was: How to transcompile python code that have logging or psutil libraries imported.)

[nutant-h]

I am trying to transcompile a Python file into Go.

Following the README file I installed grumpy, then tested it;
#echo 'import sys; print sys.version' | grumprun
2.7.13
works fine.

My python code needs logging and psutil libraries imported;
but executing echo 'import logging, psutil, sys; print sys.version' | grumprun throws the following error.

# echo 'import logging, psutil, sys; print sys.version' | grumprun

I am sure there must be a way to use other libraries. How can I use logging library?
I am just not able to find the documentations, need help.

Thank you.

Followed the above mentioned wiki.
though getting the same error.

Hi, @nutant-h

The README is outdated. I should update it. Sorry for that.

Please follow the following (copied from #79 (comment)):

• Install Python 2.7
• Install Go >= 1.10
• Install Grumpy packages for development:

cd grumpy-tools-src/
python setup.py develop

cd grumpy-runtime-src/
python setup.py develop

• Run your tests via the grumpy command line tool:

$ grumpy -c 'import sys; print sys.version'
2.7.13

This should be working.

[alanjds]

I created an issue to track the update of README on #113. Thanks for reporting.

Please feed back if my instructions had worked or not. Are the instructions clear enough?

[nutant-h]

Hi @alanjds
Followed your instructions;

I got error while doing

cd grumpy-runtime-src/
python setup.py develop

This is the error;

This is strange, as we have automated tests for Linux. A couple of questions:

• What version/distribution of Linux you are using?
• What version of Python (python --version)? Installed via apt/yum?
• The error persists if trying in a virtualenv?

I am trying to reproduce here, but it works for me

[nutant-h]

Hi

What version/distribution of Linux you are using?

root@dev-vm-charlie:~# cat /etc/os-release
NAME="Ubuntu"
VERSION="16.04.5 LTS (Xenial Xerus)"
ID=ubuntu
ID_LIKE=debian
PRETTY_NAME="Ubuntu 16.04.5 LTS"

SUPPORT_URL="http://help.ubuntu.com/"
BUG_REPORT_URL="http://bugs.launchpad.net/ubuntu/"
VERSION_CODENAME=xenial
UBUNTU_CODENAME=xenial

What version of Python (python --version)? Installed via apt/yum?

root@dev-vm-charlie:~# python --version
Python 2.7.12

The error persists if trying in a virtualenv?
Have not tried that but how would it make any difference?

[nutant-h]

I tried in virtualenv and it worked till the point where I did

cd grumpy-runtime-src/
python setup.py develop

and at the end got this;

I did copied the logging Lib from CPython 2.7 repo into third_party/stdlib.

[alanjds]

So, it is not compiling codecs.py on your env.

Last thing: please try with an standard user, not root.

I will try to create a docker machine matching yours and reproduce it.

Thanks for the effort.

[nutant-h]

Tried with ubuntu user. Got the same codecs error while doing

cd grumpy-runtime-src/
