Installation of spring on Ubuntu 16.10

[Natalia Pakharukova]

Hello!

I followed the installation process for Spring on Ubuntu 16.10 and when I tried to activate it, I got this error message: bash: spring_v0-84-1470/bin/spring: /struct/sachse/casa/08_python/spring_v0-84-1470/bin/python: bad interpreter: No such file or directory.

What can I do to fix it?

Thanks a lot for your help!

Dear Natalia,

Thank you for posting the error. Unfortunately, there is a problem with the latest setuptools from python. This currently affects any binary install.

Just start the binary install from scratch:

% tar xvf spring-0.84.1470-linux.tar.gz
% cd spring_v0-84-1470

and follow:

1. Re-install pip

% cd patches; wget https://bootstrap.pypa.io/get-pip.py; cd ..

% PYTHONPATH=$PWD/lib/python2.7/site-packages LD_LIBRARY_PATH=$PWD/parts/EMAN2/lib ./parts/EMAN2/Python/bin/python patches/get-pip.py -U

2. Remove old setuptools and re-install latest setuptools

% rm -rf lib/python2.7/site-packages/setuptools*

% PYTHONPATH=$PWD/lib/python2.7/site-packages LD_LIBRARY_PATH=$PWD/parts/EMAN2/lib ./parts/EMAN2/Python/bin/pip  install -U --prefix=$PWD pip setuptools

Finally:

% sh patches/binary_install_linux.sh

This should work. I will update the instructions on the website.

Best wishes,

Carsten

Dear Carsten,

I followed the instructions and when I executed the command

% PYTHONPATH=$PWD/lib/python2.7/site-packages LD_LIBRARY_PATH=$PWD/parts/EMAN2/lib ./parts/EMAN2/Python/bin/pip  install -U --prefix=$PWD pip setuptools

I got this error message:

OSError: [Errno 2] No such file or directory: '/home/natalia/soft/spring_v0-84-1470/parts/EMAN2/Python/lib/python2.7/site-packages/setuptools-0.6c11-py2.7.egg'

Can you please help?

Thanks a lot!

Natalia

Dear Natalia,

I am aware of this error message - simply ignore it. When you peek into lib/lib/python2.7/site-packages you should find the latest setuptools being installed.

Just move on with:

% sh patches/binary_install_linux.sh

Best wishes,

Carsten

Dear Carsten,

Unfortunately, after the installation I still got the error message:
Spring environment loaded.
Traceback (most recent call last):
  File "/home/natalia/soft/spring_v0-84-1470/bin/spring", line 133, in <module>

ImportError: libpng12.so.0: cannot open shared object file: No such file or directory

Testing also failed with the same error. What can I do to fix it?

Thank you for your help!

Dear Natalia,

It seems that the latest Ubuntu does not have the option of installing libpng12

The problem has been resolved in the following thread:

https://askubuntu.com/questions/840257/e-package-libpng12-0-has-no-installation-candidate-ubuntu-16-10-gnome/840268

It should fix the import error.

Best wishes,

Carsten
