Hashtable can't build

[nammn]

Running: $npm install returns with the following error:

newer osx/xcode version doesn't ship with unordered_map. Therefore compilation doesn't work. Any idea how to solve this?

Hashtable has an PR, which is sadly still open. https://github.com/chad3814/node-hashtable/pull/31

hmmm, I'm surprised no one else has hit this yet if its been this way for so long. I don't have a OSX system to test with either...

If we assume there is no way around the error, then I guess you could clone the hashtables repo, apply that guys PR, and then install hashtables from the file source with npm install <hashtables folder name here>

then if you run npm install, npm should see that hashtables is already installed (thus it'll skip it).

Actually I tried that. TBH my nom knowledge is limited. I did the following, as mentioned in this post: http://qiita.com/Keech/items/d866870416705b0e8e71

• installed from hashtable from the PR (npm install "https://github.com/fabrice102/node-hashtable.git")
• copied the content from node_modules over to the one in marbles
• run npm install again -> sadly they removed my hashtable package and tried to use the old one again.

After that I tried to install that pr hash table globally with the option -g. Still doesn't work. Still tries to use the old hashtable. Any suggestions there?

hey that's pretty cool, didn't know you could do it directly from a PR.

it may be conflicting with shrinkwrap.

1. remove the hashtable entry starting at line 1151.
2. run your command npm install "https://github.com/fabrice102/node-hashtable.git" from marbles itself
3. then npm install from marbles

if that still doesn't work delete the npm-shrinkwrap.json file entirely, and repeat.

Removing the line as you have mentioned worked out for me! npm install went through. Thanks!
