import tfjs-node and build via webpack,babel - error node-pre-gyp
See original GitHub issueHi, I’m trying to break tfjs-node in vain the next day. When compiling using a webpack, I get errors from the node-pre-gyp package. I tried all possible ways I found in the forums, but nothing helps. I tried downgrading tfjs-node to version 1.2.1, but also without effect. I also tried the node in 8. I import the package according to the example. Is there a bug in building with a webpack with a babel?

@kangyizhang @jakubfrydrych hello , i am struggling with the exact same error
I do not understand what do you mean when you say that you have “installed tensorflow library”, should i install it from pip or put the Tensorflow C library folder somewhere ? how does tfjs-node know where my tensorflow C library is located ?
thank you very much
I’m getting the same errors. webpack-node-externals didn’t help.
