Invalid ELF header with node bcrypt on AWSBox

Question

I'm playing with awsbox and deploying my app shows these errors:

    /home/app/code/node_modules/mongoose-troop/node_modules/bcrypt/node_modules/bindings/bindings.js:79
            throw e
                  ^
    Error: /home/app/code/node_modules/mongoose-troop/node_modules/bcrypt/build/Release/bcrypt_lib.node: invalid ELF header

        at Module.load (module.js:356:32)
    warn: Forever detected script exited with code: 1
    warn: Forever restarting script for 1 time

Any idea how to resolve this?

Answer 1

Please reinstall your bcrypt module by npm install then restart the server. Should be solved.

Answer 2

Not sure what the best answer might be but I did find some post mentioning something about x86 vs 64 bit issues. I deleted the mongoose-troop module and called npm install from within the awsbox console and that seemed to have done it. Not sure how that will work as far as deploying to awsbox though. Might not work

Answer 3

[edit] I had the same error for another reason (see comments), just in case it works for someone else: I solved it by re-installing the bcrypt module by npm with this command:

npm install bcrypt
