Does Twilio Flex UI support Node 18 and NPM 8?-CodePudding

I am trying to follow the instructions from Twilio Flex found at: Twilio Flex Quickstart: Getting Started with React Plugin Development

I keep running into errors and can not figure them out. I've tried doing this on Windows and macOS and it's the same result. I am using NVM to use Node.js v18.13.0 and NPM v8.19.3. The only thing I can think of is that maybe Twilio Flex does not support the current versions of Node and NPM. Does anyone know what I'm doing wrong?

Terminal output:

Node.js v18.13.0

Here is the commands I have run so far (in order):

curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.39.3/install.sh | bash
nvm install --lts
brew tap twilio/brew && brew install twilio
twilio login
twilio flex:plugins:create plugin-sample --install --flexui2
cd plugin-sample
twilio flex:plugins:start

I have tried installing legacy versions of Node 16 and Node 14 with varying degrees of success. At one point I was able to actually have the plugin running on localhost but I had many errors and it would not let me publish the plugin. Since then, I have not been able to recreate this somewhat successful output.

CodePudding user response：

According to the installation instructions, Node 10.12 through 14 are supported. They are working towards support for 16. So using node 18 would be a very likely cause of the error.

You can switch to a supported version by doing nvm install 14.

To keep this version as your new default, you'll need to set it: nvm alias default 14.
