Npm fails to parse JSON data on bench init

First post. Thanks for a very interesting frappe framework, which I am eager to learn in detail and to which I eventually hope to contribute.

Following the Manual Install guide for frappe/bench, I’ve managed to overcome a number of hurdles thanks in large part to previous posts in this discussion forum. Now appear to be very close to completing a successful init, but here’s an issue for which I’ve not seen a prior discussion and solution. npm appears to be croaking on the file ‘/home/ubuntu/.npm/yeast/0.1.2/package/package.json’ and it is pointing fingers at the package author.

Can anyone please confirm from scanning the following output whether this is indeed the case and how I should attempt to resolve this issue?

I’m working this in a Vagrant/Virtualbox environment, as can be deduced from the terminal output, just below. Following on, I’ve pasted in the relevant tail-end of the npm-debug.log. Thanks.

Seems like an npm install issue. Maybe you lost network (or just search for npm issues on the net)

Thanks for your reply. Your suspicion of an npm install issue became my main theory too upon noticing the file .npm/yeast/0.1.2/package/package.json was incomplete with no EOF. so I deleted the .npm directory along with frappe-bench directory, purged and reinstalled npm with apt and finally ran bench init frappe-bench again with better success. However, a warning is output. Here is the relevant bit, which appears following output of the install file tree:

npm WARN enoent ENOENT: no such file or directory, open ‘/home/ubuntu/frappe-bench/package.json’
npm WARN frappe-bench No description
npm WARN frappe-bench No repository field.
npm WARN frappe-bench No README data

It’s a mystery to me why the file in question is simply absent or what is its origin, because presumably I could copy it in the place indicated if I knew where it resides.

At any rate, I’m a bit further along, having attended to several warnings output by redis following bench start. Nginx is running and displays on localhost:8080 whilst localhost:8000 does not make any connection. In short, ERPNext doesn’t appear and as yet I’ve not encountered any indication as to why.

If anybody has any theories about this, please chime in. Thanks.
