Not able to install

[E3V3A]

Hi @eouia

I'm following your wiki instructions, but the installation fails with:

$ npm install

> [email protected] preinstall /home/pi/MagicMirror/modules/MMM-Assistant/node_modules/snowboy
> npm install node-pre-gyp

npm notice created a lockfile as package-lock.json. You should commit this file.

That file does not exist and seem outdated. But I found one here: https://storage.googleapis.com/grpc-precompiled-binaries/node/grpc/v1.7.1/node-v59-linux-arm.tar.gz

However, I don't know where that file belong, do you? Either way, I did this:

cd ~/Downloads
wget https://storage.googleapis.com/grpc-precompiled-binaries/node/grpc/v1.7.1/node-v59-linux-arm.tar.gz
tar -zxvf node-v59-linux-arm.tar.gz 
cd node-v59-linux-arm
mkdir -p /home/pi/MagicMirror/modules/MMM-Assistant/node_modules/google-assistant/node_modules/grpc/src/node/extension_binary/node-v59-linux-arm/
cp grpc_node.node /home/pi/MagicMirror/modules/MMM-Assistant/node_modules/google-assistant/node_modules/grpc/src/node/extension_binary/node-v59-linux-arm/.
cd /home/pi/MagicMirror/modules/MMM-Assistant/
npm install

That resulted in the following message:

npm notice created a lockfile as package-lock.json. You should commit this file.
npm WARN [email protected] No repository field.
npm WARN [email protected] No license field.

removed 23 packages in 26.832s

Not sure if this went well, because I cut the install short the first time when it failed finding that file.

So I did this:

So tried to do the auth thing, that also failed:

$ node google-auth.js

This is the same issue as in #11

@eouia Perhaps this could have something to do with this?

Google changed their Assistant API to include model-id: Assistant(credentials, device_model_id)...

Well, First, sorry for my late update. I should do my job so I couldn't make time to maintain this. I hope I could get the time in a month.

I hadn't tested but I suspect it was caused by the old version dependencies in package.json. I had to fix the version constantly for escaping some urgent bugs at that time a few months ago. After time, it makes my code to be unstable.

I have no time to research it currently, But if you have some luck, this could be a help. Reinstall it with this package.json

1. ok, it made two manual compiles with lots of deprecation warnings.

• Why is the gRPC so old?

2. Then the google_auth.js copy paste worked, even with this error:

$ node google-auth.js

• How can we fix?

3. The post installation part take too long...

• Why is the post installation part needed? What does it do exactly?

npm install --save-dev electron-rebuild && ./node_modules/.bin/electron-rebuild --pre-gyp-fix

It took ~ 25 min (RPi3)

1. Why is the gRPC so old? I haven't updated the package.json for newer dependencies. new gRPC is published a few months ago(one or two months). I had no time to update it. npm tried to install many dependencies with newer version, but I fixed it with some specific versions. That makes this kind of warnings and errors.

2. How can we fix?(Google Auth.js) Regardless of errors, if you can get token.js in resources directory, you don't have to care this error anymore. Just forget it. Anyway, this error is caused by version of node of MagicMirror. As I know, MM use lower version node for stability. Google-Auth.js uses some functions in higher node version. I doubt this error is placed when you try this again after recompilation.

3. That point is the core problem on the installment of this module. MagicMirror, Google Assistant, Google Cloud Speech and Snowboy are using DIFFERENT VERSION OF NODE AND DEPENDENCIES EACH OTHER. That commands makes some node dependencies executable by recompiling after installment. By example, google-auth.js will be failed after this recompile. So you should finish step 3-1 before 4. And current snowboy modules doesn't work with current MagicMirror Electron version. So in step 4, it is recompiled for compatibility.

Thanks for your effort in explaining! I'm very grateful. :1st_place_medal:
