Unable to build a project on MacOS 10.11.2

I get python error when trying to build a simple one-file solution:

Wow! I don't know what I should to do here http://stackoverflow.com/questions/1746825/python-valueerror-insecure-string-pickle

are much more likely than a never-observed bug in Python itself in a functionality that's used billions of times a day all over the world

😄

Looks like internal Python's problem. Could you try to install platform manually?

> platformio platforms install atmelavr

[neverov]

Hmm, definitely looks like a python problem.
I tried with python out-of the box 2.7.10 and python from homebrew, which is 2.7.11 and the result persists. :(

Which version do you use?

[ivankravets]

I've never seen this error. I use default Python in Mac OS X

python --version
Python 2.7.10

Could you try

> shasum /usr/bin/shasum

?

[neverov]

Gives me: dcb56150088c64188cfcbf84cb0fc0b83f00a7a1 /usr/bin/shasum5.18.

I guess the problem is in my python setup, I'll try to play with virtualenv tomorrow and figure out what's going wrong.

[ivankravets]

Test this please

>>>

Does it work for you?

[neverov]

Yep, exactly the same result

Now it looks interesting... And

[neverov]

Here we go:

>>> subprocess.check_output(["sha1sum", "/usr/bin/shasum"])
