error C2039 ‘Buffer’ is not a member of ‘node’


When I ran a build for C++ code by node-gyp, the following error occurred.

$ npm run build

> module-name@2.9.14 build D:\development\software-name\src\modules\module-name
> sh

I tried to rebuild node-gyp but it didn’t solve the problem. The problem was that C:\Users\user_name\AppData\Local\node-gyp\Cache\12.16.1\include\node\node_buffer.h was empty for some reason. nan.h includes the file but the build of course fails without the implementation. It must have the implementation but not.

Once I deleted C:\Users\user_name\AppData\Local\node-gyp\Cache folder, the build succeeded again.
