TASK [lk-django : install python requirements] -> fatal: [default]: FAILED!

[serhiipalash]

Hi!
Can anyone help me with raising LaunchKit? I do everything like it is described in README, but I always get error with installing six package.

Thanks in advance!

[sunweiyang]

I'm having the same problem. This seems to be the trouble:

:stderr: cheetah 2.4.4 requires Markdown>=2.0.1, which is not installed.
launchpadlib 1.10.2 requires testresources, which is not installed.
tweepy 3.3.0 has requirement six>=1.7.3, but you'll have six 1.5.2 which is incompatible.
Cannot uninstall 'requests'. It is a distutils installed project and thus we cannot accurately determine which files belong to it which would lead to only a partial uninstall.

[sunweiyang]

@serhiipalash I was able to perform a (maybe) workaround.

I'm not sure if this causes any side effects (for example, I now have a connection reset problem when going to http://localhost:9100), but it at least gets us through Ansible.

Steps:

After the Python failure, the Vagrant machine should still be up.
From the LaunchKit directory, I connected to the Vagrant machine:

vagrant ssh

I then ran the following pip install command (which addressed the specific package issues I saw for six, markdown, testresources, and requests) and exited the connection:

sudo pip install --ignore-installed six==1.7.3 markdown testresources requests requests[security]
exit

I then restarted the Vagrant machine:

vagrant halt
vagrant up --provision

[dominicrico]

#44 and #43 could be fixed by installer missing node_modules in the skitfolder.

The webserver could never spin up because of the missing node_modules...

[samuelpodina]

I managed to get it working following @sunweiyang workaround and then ran npm i in the skit folder followed by vagrant halt vagrant up --provision.

[j0nscalet]

I've followed those steps as well and got it working, as well. Thanks @samuelpodina @sunweiyang!
