尝试在 windows 10 上安装 node-ffi 会出现错误：error C2660: 'v8::FunctionTemplate::GetFunction': function does not take 0 arguments

Question

I'm trying to install node-ffi as a package in one of my electron applications. doing a straight " npm install node-ffi" failed... so I ended up trying the "Source Install" section found here:

  https://github.com/node-ffi/node-ffi

What I've Done So Far:

  npm install --global windows-build-tools

This created the following folder:

PS C:\Users\jmk\.windows-build-tools> dir
Directory: C:\Users\jmk\.windows-build-tools

As yo u can see it installed python2 but I changed the default python that node-gyp uses like so:

PS C:\Users\jmk\source\github\node-ffi> npm config set python C:\Python38\python.exe

And then confirmed like so:

nPS C:\Users\jmk\source\github\node-ffi> node-gyp configure

now when i do a "node-gyp build" or rebuild, i see errors like:

I tried to track down the first error. This is what ffi.cc(49,57) looks like:

Nan::New<FunctionTemplate>(FFIPrepCif)->GetFunction());

And this is what C:\Users\jmk\AppData\Local\node-gyp\Cache\12.18.4\include\node\v8.h(6126,46) looks like

  /** Returns the unique function instance in the current execution context.*/
  V8_WARN_UNUSED_RESULT MaybeLocal<Function> GetFunction(
      Local<Context> context);

So it seems the new version of v8 requires that GetFunction be passed a context? not sure. I'm not JS programmer nor C++ programmer. I thought if it was something simple, like installing some new library?

https://github.com/node-ffi/node-ffi/tree/master/src is the code I'm essentially dealing with at this point.

Can you point me in the right direction please?

thanks.

Answer 1

Node-ffi is no longer maintained and doesn't work with Node versions > 10, use node-ffi-napi instead. There are a number of related packages that are also no longer maintained and have napi functioning forks (eg ref-napi, ref-wchar-napi).

The old packages and the napi forks have the same API as far as I can tell, so you just need to install the new versions and change the imports in your code and it should install and run.
