Issue with running commands in starcluster README

[kk663]

I run all the steps in the starcluster README up to this step: starcluster start mycluster

I get the error below on a Mac. Could you please tell me what is causing the error?

error occurred in job (id=node001): 'EntryPoint' object has no attribute 'resolve' Traceback (most recent call last): File "/Library/Python/2.7/site-packages/StarCluster-0.95.6-py2.7.egg/starcluster/threadpool.py", line 48, in run job.run() File "/Library/Python/2.7/site-packages/StarCluster-0.95.6-py2.7.egg/starcluster/threadpool.py", line 75, in run r = self.method(_self.args, *_self.kwargs) File "/Library/Python/2.7/site-packages/StarCluster-0.95.6-py2.7.egg/starcluster/cluster.py", line 1429, in self.pool.map(lambda n: n.wait(interval=self.refresh_interval), nodes, File "/Library/Python/2.7/site-packages/StarCluster-0.95.6-py2.7.egg/starcluster/node.py", line 1019, in wait while not self.is_up(): File "/Library/Python/2.7/site-packages/StarCluster-0.95.6-py2.7.egg/starcluster/node.py", line 1025, in is_up if not self.is_ssh_up(): File "/Library/Python/2.7/site-packages/StarCluster-0.95.6-py2.7.egg/starcluster/node.py", line 1010, in is_ssh_up return self.ssh.transport is not None File "/Library/Python/2.7/site-packages/StarCluster-0.95.6-py2.7.egg/starcluster/node.py", line 1070, in ssh private_key=self.key_location) File "/Library/Python/2.7/site-packages/StarCluster-0.95.6-py2.7.egg/starcluster/sshutils.py", line 78, in init self._pkey = self.load_private_key(private_key, private_key_pass) File "/Library/Python/2.7/site-packages/StarCluster-0.95.6-py2.7.egg/starcluster/sshutils.py", line 89, in load_private_key pkey = self._load_rsa_key(private_key, private_key_pass) File "/Library/Python/2.7/site-packages/StarCluster-0.95.6-py2.7.egg/starcluster/sshutils.py", line 184, in _load_rsa_key passphrase=private_key_pass) File "/Library/Python/2.7/site-packages/StarCluster-0.95.6-py2.7.egg/starcluster/sshutils.py", line 816, in get_rsa_key password=passphrase) File "build/bdist.macosx-10.11-intel/egg/paramiko/pkey.py", line 217, in from_private_key key = cls(file_obj=file_obj, password=password) File "build/bdist.macosx-10.11-intel/egg/paramiko/rsakey.py", line 42, in init self._from_private_key(file_obj, password) File "build/bdist.macosx-10.11-intel/egg/paramiko/rsakey.py", line 168, in _from_private_key self._decode_key(data) File "build/bdist.macosx-10.11-intel/egg/paramiko/rsakey.py", line 173, in _decode_key data, password=None, backend=default_backend() File "/Library/Python/2.7/site-packages/cryptography-1.4-py2.7-macosx-10.11-intel.egg/cryptography/hazmat/backends/init.py", line 35, in default_backend _default_backend = MultiBackend(_available_backends()) File "/Library/Python/2.7/site-packages/cryptography-1.4-py2.7-macosx-10.11-intel.egg/cryptography/hazmat/backends/init.py", line 22, in _available_backends "cryptography.backends" AttributeError: 'EntryPoint' object has no attribute 'resolve'

same here. any solution to this?

surprisingly, running (??)

python -v /path-to-starcluster/starcluster start mycluster

works every now and then (i was trying to see what is happening in python and it magically went through). not always though...

[vttrifonov]

It went down to upgrading Python packages in /System and I could not figure out how to do it nicely (I am on Mac OS X El Capitain). So I ditched the default Mac OS X python installation and went with a new one from MacPorts which solved the problem.

I am having this same error in mac yosemite. Can you tell me how you exactly upgraded the python packages in mac?

You would just need to upgrade setuptools. sudo pip install -U setuptools
