Polis: gyp / bcrypt error while running npm install

[joshsmith2]

Issue encountered during an attempt to set up polisServer on Ubuntu 18.04.3 LTS (GNU/Linux 4.15.0-66-generic x86_64) according to the instructions in the readme.

The first steps go well (smoothly, even!) but npm install throws up this:

gyp: Call to '/usr/bin/pg_config --libdir' returned exit status 1 while in binding.gyp. while trying to load binding.gyp
gyp ERR! configure error

Uninstalling node-gyp and retrying gives the same error:

rm -r ~/.node-gyp/
rm -r /opt/polisServer/node_modules/

Running the offending command:

/root/.nvm/versions/node/v10.9.0/lib/node_modules/npm/node_modules/node-gyp/bin/node-gyp.js rebuild
threw up the following interesting error:

gyp: Undefined variable module_name in binding.gyp while trying to load binding.gyp

Optimistically trying to run ./x fails too, with this error:

internal/modules/cjs/loader.js:583
throw err;
^

Am getting the same error.

The bcrypt version in package.json is failing to install

You can replace this line in package.json
"bcrypt": "3.0.0",
to this
"bcrypt": "https://github.com/kelektiv/node.bcrypt.js.git#master",
then run npm install again

[joel-zilliqa]

Python is also a requirement

[joshsmith2]

Kenbok - thanks for raising that. Didn't fix the issue for me, but I've eventually managed to get npm install working. As above, it looks like there are some extra requirements.

From a fresh Ubuntu 18.04.3 instance, I needed to run:
apt install python libpq-dev make g++

which seems to fix things

[joshsmith2]

Update - while the above gets npm install to run, the server still doesn't start until package.json is updated as per Kenbok's comment above

[patcon]

I think we can close this now that we've got Dockerfiles as the canonical how-to :)

Work for me. Thanks !!!
