After installing Mautic using composer … the terminal ended with this message

```auto
> npm ci --prefer-offline --no-audit
sh: npm: command not found
Script npm ci --prefer-offline --no-audit handling the npm-ci event returned with error code 127
Script @npm-ci was called via post-update-cmd

```

I went ahead and visit which load the install page but clicking on “Next Step” button does nothing. No refresh or anything. Page just sit there

I am not sure why it doesn’t start installing or if that last error in composer install mean something and broke it.

Please advise what to do about this? We’re wanting to upgrade to 5.1 but doing a fresh new install to test first and learn the layout before upgrading our existing one.

Thank you  
Bill

npm was installed … It was missing libraries.

To those with similar error on Redhat based Linux - To fix this issue run this at root command

```auto
yum install brotli

```
