Fix Instructions for npm installing dependencies in Intranet with no access to Internet e.g. npm install npm ERR fetch failed https://github.com/rase-/node-XMLHttpRequest/archive/a6b6f2.tar.gz

How to deal with dependencies which depend on dependencies referenced with github.com rather than a version
Works for Build Servers which do not have access to the Internet, having all npm dependencies cached in local registry e.g. nexus
In case you introduce a new library or upgrade one, which relies on github.com somewhere 

Fixes 

npm install [email protected]

npm ERR fetch failed https://github.com/rase-/node-XMLHttpRequest/archive/a6b6f2.tar.gz

LOCAL_NEXUS_DOMAIN = http://nexus.dev.uk.companyName/content/groups/npm-all/

1. Install npm shrinkwrap on your local box - must be global e.g. npm install -g npm-shrinkwrap

2. Delete everything from node_modules, remove shrhinkwrap.json file (back it up)

3. Run npm install

4. Run npm shrinkwrap --dev - it will generate another npm-shrinkwrap.json file
5. Replace the references to github tars e.g.

   "xmlhttprequest": {
                      "version": "1.5.0",
                      "from": "https://github.com/rase-/node-XMLHttpRequest/archive/a6b6f2.tar.gz",
                      "resolved": "https://github.com/rase-/node-XMLHttpRequest/archive/a6b6f2.tar.gz"
    }
    
with your nexus server e.g. 

   "xmlhttprequest": {
                      "version": "1.5.0",
                      "from": "[LOCAL_NEXUS_DOMAIN]rase-xmlhttprequest/-/rase-xmlhttprequest-1.5.0.tgz",
                      "resolved": "[LOCAL_NEXUS_DOMAIN]rase-xmlhttprequest/-/rase-xmlhttprequest-1.5.0.tgz"
    }
    
Make sure that file is in nexus against the correct version of it, else:

Add the library to your registry/ nexus

npm set registry [LOCAL_NEXUS_DOMAIN]

clone the project you want to publish to nexus

modify package.json name -> e.g. "name": "rase-xmlhttprequest"
npm publish --registry [LOCAL_NEXUS_DOMAIN]content/repositories/npm-internal/

6. Repeat the process for each library e.g. 
"has-cors": {
                      "version": "1.0.3",
                      "from": "[email protected]",
                      "resolved": "[LOCAL_NEXUS_DOMAIN]has-cors/-/has-cors-1.0.3.tgz",
                      "dependencies": {
                        "global": {
                          "version": "2.0.1",
                          "from": "https://github.com/component/global/archive/v2.0.1.tar.gz",
                          "resolved": "https://github.com/component/global/archive/v2.0.1.tar.gz"
                        }
                      }
 },
 
7. Replace the remaining https://registry.npmjs.org with your nexus instance e.g.

 "resolved": "https://registry.npmjs.org/request/-/request-2.42.0.tgz"
 
with 

 "resolved": "[LOCAL_NEXUS_DOMAIN]request/-/request-2.42.0.tgz"
 
8.Commit/ push the resulting shrnkwrap.json file and the build server should read that when npm install is run
