functions: Cannot start emulator

Hi there, Refer to issue #200 I try reinstall grpc but still getting same error

After install grpc it show success but grpc_node.node is installed via remote, like this [grpc] Success: "/usr/local/lib/node_modules/grpc/src/node/extension_binary/node-v48-darwin-x64/grpc_node.node" is installed via remote

When run firebase deploy --only functions it it showing functions: Cannot start emulator. Error: Cannot find module '/usr/local/lib/node_modules/firebase-tools/node_modules/grpc/src/node/extension_binary/grpc_node.node'

I checked in directory was nothing inside /usr/local/lib/node_modules/firebase-tools/node_modules/grpc/src/node/extension_binary

Please give some advice, thank you in advance.

I had the same issue when I ran on my Mac OS X High Sierra (not clear if this happens on Windows or Linux platforms)

sudo npm install -g firebase-tools

Error/Warning:

gyp WARN EACCES user “root” does not have permission to access the dev dir “/usr/local/lib/node_modules/firebase-tools/node_modules/grpc/.node-gyp/8.9.1” gyp WARN EACCES attempting to reinstall using temporary dev dir “/usr/local/lib/node_modules/firebase-tools/node_modules/grpc/.node-gyp”

Here is what I did to avoid this: sudo mkdir -p /usr/local/lib/node_modules/firebase-tools/node_modules/grpc/.node-gyp/8.9.1/

This creates an empty directory with the path specified then rerun the following: sudo npm install -g firebase-tools

I hope this helps.

Similar issue - I’ve found various other threads on here related to this, but none of them seem to work. For me, somehow not only am I getting the above error: Cannot start emulator. Error: Cannot find module ‘/usr/local/lib/node_modules/firebase-tools/node_modules/grpc/src/node/extension_binary/grpc_node.node’

But for me when I use “sudo npm install -g grpc” I get the following error:

node-pre-gyp ERR! Tried to download(undefined): https://storage.googleapis.com/grpc-precompiled-binaries/node/grpc/v1.7.0/node-v57-darwin-x64.tar.gz node-pre-gyp ERR! Pre-built binaries not found for grpc@1.7.0 and node@8.9.0 (node-v57 ABI) (falling back to source compile with node-gyp) gyp WARN EACCES user “root” does not have permission to access the dev dir “/Users/michaelrhanscom/.node-gyp/8.9.0” gyp WARN EACCES attempting to reinstall using temporary dev dir “/usr/local/lib/node_modules/grpc/.node-gyp”

Where the last 2 gyp warnings continue to populate on the screen over and over until I terminate the process. I tried to use “sudo npm install -g grpc --allow-root --unsafe” which seemed to work, but when I go back through the various folders, I still get down to '/usr/local/lib/node_modules/firebase-tools/node_modules/grpc/src/node" and then beyond that the folder for “extension_binary” doesn’t even exist. Additionally, for the path within the above error, within the node_modules/grpc, the folder .node_gyp also doesn’t exist. Help?
