Error installing bcrypt in Linux Mint

[AlbertoElias]

Hi, I needed to install mongoose-auth which needs bcrypt and I get the following error:

I've tried a lot of different things but I haven't managed to get it working...

Do you have the includes for openssl?

[AlbertoElias]

What do you mean? I know I have openssl installed.

[ncb000gt]

Yes, but this is a native module that needs to be compiled. Thus it needs the header files.

[AlbertoElias]

I'm not quite sure I understand you. How am I supposed to solve this? I remember installing bcrypt on my mac and not getting any problem at all, but I get this strange problem with Linux Mint...

[ncb000gt]

I'm not familiar with Mint but if it uses apt for packages you should likely be able to install libssl-dev (depending on the repos) and shouldn't have an issue after that.

That said, if it doesn't then you'll need to figure out how to install those dev headers for openssl onto your system. MacOS has the header files already. Ubuntu did not, but sudo apt-get install libssl-dev solves that issue on Ubuntu.

If you're unfamiliar with header files then you'll want to read up on those for future reference. http://www.learncpp.com/cpp-tutorial/19-header-files/ or any other resource on google can cover it.

[AlbertoElias]

I already did that before installing node.js and I still get this error...

[AlbertoElias]

Oh, and I should add that Linux Mint is based on Ubuntu

[ncb000gt]

Have you verified that the headers exist where you the module is expecting them to be? Check the wscript for the locations. The reason I'm asking is because it looks like (from the configure output) that the rand_bytes function could not be found. This happens on some systems (mac i believe) but is ok? on linux it doesn't seem to be.

Another alternative from the output is that node-waf is doing something weird, but I suspect there is something up with the includes.

[AlbertoElias]

I decided to try removing everything related to node.js and install it again and amazingly it's working. I also checked what you mentioned, and at least this time, it's fine, so maybe it was related with that. Thanks for your help.

[ncb000gt]

Sure. Sorry I couldn't be of more help.
