I am trying to build a native module on Node version 6.12.3 with target set to Node version 10.x. But the node-gyp command error out message:
gyp: name 'build_v8_with_gn' is not defined while evaluating condition 'build_v8_with_gn == "true"' in binding.gyp while trying to load binding.gyp

Here are the commands I am invoking:

node --version
v6.12.3

~/{nodeSourceCodeLocation}/lib/node_modules/npm/node_modules/node-gyp/bin/node-gyp.js --version
v3.4.0

~/{nodeSourceCodeLocation}/lib/node_modules/npm/node_modules/node-gyp/bin/node-gyp.js rebuild --verbose --target=v10.4.0 --release

gyp info it worked if it ends with ok

The same issue is seen here prebuild/prebuildify#10 and there are insights on how to reproduce it.

build_v8_with_gn is coming from Node.js v10's common.gypi. As a workaround you can pass --build_v8_with_gn=false to node-gyp or npm.

Does it also happen with node-gyp 3.6.0?

[kanikashah90]

The workaround worked. Thanks :)

Yeah, it also happens with node-gyp 3.6.0
