Build from pypi fails for Python3.7

[zefciu]

While it is possible to install line_profiler from source, installing it from PyPI fails. Probably a separate distribution for this version should be created. Message from pip:

I can confirm this issue and many others out there seem to have been fixed, e.g. https://github.com/numpy/numpy/issues/10500

[beaugunderson]

also confirming that PyPi installation fails but

pip install Cython git+https://github.com/rkern/line_profiler.git

succeeds

[scoder]

@rkern, would be nice to rebuild the existing sources with a recent Cython version and deploy it as a fix release to pypi. Also see the test fix in #129.

[kawing-chiu]

Same issue here. Cannot install line_profiler for python 3.7.

[meownoid]

Same issue.

[phewdry]

is cython required for line profiler? seems memory profiler is fine w/o afaik. Context: using in jupyter notebook/ipython environment (Mac OS Mojave)

Note: Doesn't seem ipython is even compatible w/ 3.7 yet. How are you guys using lineprofiler?

Update: pip3 install line_profiler returns this error (Is this related to Cython or solely from lineprofiler?):

sudo pip3 install Cython git+https://github.com/rkern/line_profiler.git returns this error:

[holmrenser]

This still happens

[simonpercivall]

A bad solution, I know, but I've published a package lp37 on PyPI to solve this issue.

[ngoldbaum]

Please do a release on pypi pretty please

[caethan]

Sorry folks, new baby has been limiting my time. Going to try to get these major fixes in but no guarantees on timing.

I have met this question tonight and cried until now, but it resolved by: pip install cython then sudo pip3 install Cython git+https://github.com/rkern/line_profiler.git lets have a look pip install line_profiler

thx @beaugunderson @ChanForPres

[psteinb]

I can confirm, from fc29 and python3.7.2, I did:

$ pip3 install --user Cython git+https://github.com/rkern/line_profiler.git

And that works flawlessly so far.
