npm install in fabric demo throws error : ...nan_maybe_43_inl.h:112:15: error: no member named 'ForceSet' in 'v8::Object' about education HOT 6 OPEN

@sornss
I have tried that earlier but no luck.

The problem is that package.json file of git project points to nan 2.7.0 .. whereas It should point to nan 2.10.0..

What changes do I make to make it right ?

I also ran into this problem. Attempting an npm update also failed, with npm suggesting I change ownership of the .config file in my home dir:

sudo chown -R $USER:$(id -gn $USER) /home/<username>/.config

After I did this I ran npm update followed by npm install. This seems to have fixed the issue.

Had the same issue on Mac OS X Hight Sierra. Seems like nan version used by fabric-client is too outdated. I had no time to investigate all the details and try different combinations of node/npm/dependencies and fight build issues on my Mac. So I just spin up a docker container with node version 8 (had this one already pulled, but I think any other version will work too). The only thing I need to fix is URLs used by client application. Here is an instruction

cd ./education/LFS171x/fabric-material/tuna-app

# remove already installed modules, because inside docker there would be other platform tools
rm -rf node_modules  

# patch URLs, we will need it soon
grep -rl "localhost" --exclude-dir node_modules . | xargs -n 1 sed -i'.bak' 's/localhost/host.docker.internal/'

# spin docker container 
docker run -it -v `pwd`:/usr/src/app -p 8000:8000 --name edx-tuna-app node:8 bash

Once image will be downloaded you will see a prompt like root@703e329f2451:/usr/src/app# type following instructions there

cd /usr/src/app
npm install [email protected]
npm install fabric-ca-client
npm install

# create dir for credentials
mkdir ~/.hfc-key-store/

Now you're ready to start, just execute following instructions (in the same session).

node registerAdmin.js
node registerUser.js
node server.js

Now if you'll open http://localhost:8000 you should see an application interface.

How about:

npm uninstall nan
npm install https://github.com/nodejs/nan

and try again

Try Removing the node_modules folder. Then try npm install.
Also from what I see your problem is not with nan but with fabric-client.
Try
npm install fabric-client
npm instal fabric-ca-client

from education.

Same problem here. Nothing helps so far.. but I am using Mac
