Install failing (Mac OSX)

[nicosandller]

I'm trying to install pyethereum by runing :

sudo python setup.py install --user

but it fails to install by returning:

         ^

error: Setup script exited with error: command 'cc' failed with exit status 1

am I missing something? I checked and OpenSSL is installed on my computer, and it seems to be working. I see that the build is not passing for OSX, is this related?

Thanks

@nicosandller what was the problem? I had the same

[nicosandller]

@yanik5 I don't remember :S. I think I just gave up and installed it on an Ubuntu VM. You should also try koding.com, it came in pretty handy.

You can work around this issue by installing scrypt manually via pip first and pointing it to the OpenSSL library.

env LDFLAGS="-L$(brew --prefix openssl)/lib" CFLAGS="-I$(brew --prefix openssl)/include" pip install scrypt

@conor10's workaround fixed the installation on mac for me

[pipermerriam]

I believe you can also do brew link openssl --force to fix this for future install without having to do the env variables.

I am trying to install pyethereum on OS Sierra and getting the below error.

P.S: @conor10 workaround fixed the installation error for openssl on mac for me but now I'm stucked at py-ecc. The first comment to the problem quoted by @nicosandller came after an year. I am just hoping I dont have to wait so long. :-|

I got around the OpenSSL error by doing sudo env LDFLAGS="-L$(brew --prefix openssl)/lib" CFLAGS="-I$(brew --prefix openssl)/include" python3 setup.py install but now I'm coming across, "error: [Errno 2] No such file or directory: 'README.md'
"

Do check if you have libtools installed brew install libtools.
