Nodejs Bcrypt + Heroku fail deploy : <p>i am having problems when i try to do a deployment in heroku.  The funny part is this was working three days ago. Also, is working fine in local machine.</p>

<p>The version of Bcrypt is 3.0.0, node 8.12.0</p>

<p>I really need to deploy this server. Could you please show me how to fix this error? I have tried some solutions I found but nothing worked. I even tried to uninstall and install again Bcrypt but does not work.</p>

<p>Thanks for the help. </p>

<p>This is the log.</p>
