Hi There!

I installed 2.7 anaconda today , after installation jupyter failed to launch with below error Last login: Fri Jul 7 10:35:14 on ttys002 /Users/arunadas/anaconda/bin/jupyter_mac.command ; exit; Python 2.7.10 (default, Jul 30 2016, 19:40:32) [GCC 4.2.1 Compatible Apple LLVM 8.0.0 (clang-800.0.34)] on darwin Type "help", "copyright", "credits" or "license" for more information.

/Users/arunadas/anaconda/bin/jupyter_mac.command ; exit; File "", line 1 /Users/arunadas/anaconda/bin/jupyter_mac.command ; exit; ^ SyntaxError: invalid syntax

Additional info My m/c is Macbook pro OS - MacOS siera , version 10.12.3 python is 2.7.10

Please suggest a work around or link to another version for overcoming version issue

I don't know what that jupyter_mac.command file is - you may need to file an issue with anaconda about it, because I think it's something they add to our code.

Sure will do , thanks!

I got a different error..:

During handling of the above exception, another exception occurred:

BTW here's my ~/anaconda3/bin/jupyter_mac.command

DIR=$(dirname $0)

$DIR/jupyter-notebook

Ok I was able to bypass this error with using: sudo jupyter notebook --allow-root

Because the error was related to mkdir permission.

We really don't recommend running Jupyter as root - the --allow-root flag is meant to be a signal that it's a bad idea. That error probably means that either some environment variable is set wrong, or there's something unusual about folder permissions.
