Node.JS Error in FreeBSD
<p>I develop Node.Js in Ubuntu and deploy it to a server running FreeBSD. When I run npm start, I got this error</p>

<pre><code>Error: Shared object "libpthread.so.0" not found, required by "bcrypt_lib.node"
at Error (native)
at Object.Module._extensions..node (module.js:440:18)
at Module.load (module.js:357:32)
at Function.Module._load (module.js:314:12)
at Module.require (module.js:367:17)
at require (internal/module.js:16:19)
</code></pre>

<p>I couldn't find the solution. How to fix it?</p>
