Node Bindings

[mishra123]

I have set up the installation files on windows and I am able to run it using command line utility. But the problem is when I set up the node bindings with "npm install openvenues/node-postal", it gives me stack of error messages. Please see below:

\AppData\Roaming\npm\node_modules\npm\node_modules\npm-lifecycle\node-gyp-bin\....\node_modules\node-gyp\bin\no
de-gyp.js" rebuild ) else (node "C:\Roaming\npm\node_modules\npm\node_modules\node-gyp\bin\node-
gyp.js" rebuild )
Building the projects in this solution one at a time. To enable parallel build, please add the "/m" switch.

Can you help me resolve the error?

node-postal has only been tested on Mac and Linux, not Windows. Support for Windows was only recently added in the libpostal C library (has to be compiled with MSYS2), but not sure if node-postal would work unmodified. If you get it working, please feel free to make a pull request. Otherwise it's best to use a Linux VM or container if possible.

Now, I am doing it on Amazon EC2 Linux. when I run "npm install openevenues/libpostal", it gave me the following error:

How shall I resolve this?

[albarrentine]

Make sure to install libpostal first, as mentioned in the README. It’s not currently possible to install node-postal with one command. The C library needs to be installed separately.

[mishra123]

Yeah I have installed libpostal on EC2 before setting up node-postal. I have followed the following steps:

1. sudo yum install curl autoconf automake libtool pkgconfig
2. git clone https://github.com/openvenues/libpostal
   cd libpostal
   ./bootstrap.sh
   ./configure --datadir=[...some dir with a few GB of space...]
   make -j4
   sudo make install

sudo ldconfig

3. sudo npm install -g node-gyp

4. npm install openvenues/node-postal - This is the step where the error in the previous post was occurred.

I am actually setting up AWS Lambda with node-libpostal. I am deploying the executables from EC2 on to S3 bucket which will be executed by Lambda. But I cannot go any further as I am stuck with step 4 above.
Please help me with this.

Hi @mishra123 , Were you able to find a solution for running the libpostal in AWS lambda?

[RayRenteria]

Hi @mishra123 , I too am interested in hearing about your efforts in deploying libpostal onto AWS Lambda.

[danielmklein]

Hello all -- I stumbled upon this while trying to deploy a Lambda function that uses pypostal and just wanted to chime in (with some bad news). It appears to me that, it's not going to be possible to deploy code that uses libpostal to AWS Lambda, barring something I'm missing or not understanding. This is given that Lambda's 250MB cap for deployment packages (including function code and all layers) and that libpostal appears to blow up if the data directory is not present. In my testing, I see my data directory taking up almost 2GB.

I would love to be proven wrong here! If anyone out there has any tips for working around this, I am all ears.

With the new EFS and Fargate integration, this should at least be possible now - whether you'd want the data dir effectively NFS mounted is another story alltogether though....

Could you elaborate a bit on this?
