npm commands don't work using git bash on windows after "link"

[tpburch]

Steps to Reproduce:

1. Follow the Git Bash on Windows instructions for installation
2. Install a node version (I installed v10.15.1 through the initial setup by calling nvs)
3. Setup the version as default with "link" (I used nvs link 10.15.1)
4. In a new Bash shell, run npm -v

Expected result:

• You should see the installed npm version

Actual result:

• got the below error:

  
  $ npm -v
  internal/modules/cjs/loader.js:583
  throw err;
  ^

Error: Cannot find module 'C:\Program Files\Git\Users{username}\AppData\Local\nvs\default\node_modules\npm\bin\npm-cli.js' at Function.Module._resolveFilename (internal/modules/cjs/loader.js:581:15) at Function.Module._load (internal/modules/cjs/loader.js:507:25) at Function.Module.runMain (internal/modules/cjs/loader.js:742:12) at startup (internal/bootstrap/node.js:283:19) at bootstrapNodeJSCore (internal/bootstrap/node.js:743:3)

I found when I inspected `PATH` in this shell, the path to the `nvs/default` folder was a windows-style path, not a POSIX path.

I was able to get this working locally by changing the entry in my .bashrc to:

export NVS_HOME=`cygpath "$LOCALAPPDATA/nvs"`
. $NVS_HOME/nvs.sh

Got the same issue and the change with cygpath also fixed it for me.
