Import Numpy Error

[Former user]

I have pypy 2.5 (installed via brew), on Mac OS 10.10. Numpy installation on pypy was smooth, but got an error message when trying to import numpy:

Traceback (most recent call last):

Any help would be greatly appreciated!

could be a duplicate of #21, do you have an older pip? You should have pip 6.0.8 or newer

[Alexander Nechiporuk]

I have the same problem on Ubuntu 12.04 pip 7.0.3 PyPy 2.6.0

[Ronan Lamy]

@anechiporuk How did you install numpy?

[Maxim Tsoy]

same here, pypy 2.6.0, MacOS 10.10, numpy installed into virtualenv from git using pip, as suggested in the docs.

I have the same problem. MacOS 10.10 pypy 2.6.0 pip 7.1.0 I installed numpy by: pypy -m pip install git+https://bitbucket.org/pypy/numpy.git

[mattip]

Non of the core pypy-numpy developers have access to MacOS. We will need detailed logs from pip, since this seems to be an issue of pypy + pip + numpy. Note that we have yet to see a failure for the first pypy-numpy installation method which avoids using pip.

MacOS 10.9.5, pypy 2.5.0 (via brew). Numpy was installed via "pypy setup.py install" (from git master)

@maksym_ganenko That's a different issue. Try to run sudo pypy -c 'import numpy' once. If it doesn't work, you may have to upgrade to PyPy 2.6, we only support the last release.

[Maksym Ganenko]

@rlamy Thank you, that helped! Now I can import numpy without sudo. To my shame, It had been written on pypy page.
