"Error: Cannot find module 'readable-stream'" when running heroku update

[Taytay]

To my knowledge, this Heroku installation on Linux has been working for some time without issue. However, now I get the following error when running heroku update:

$ heroku update
heroku-cli: Updating plugins...
 ▸    module.js:341
 ▸        throw err;
 ▸        ^

no plugins to update.
 !    To update this version of the Heroku client please use
 !    `apt-get install heroku-toolbelt`

I do not know if this is a factor or not, but here are my plugins:

$ heroku plugins
=== Installed Plugins
heroku-apps@1.2.4
heroku-cli-addons@0.2.1
heroku-fork@4.1.1
heroku-git@2.4.5

do you get this consistently? what is the output of heroku version?

[Taytay]

I did get it consistently, and then I uninstalled and reinstalled, and that fixed it, so we can close this. Here was the version info at the time:

heroku version
heroku-toolbelt/3.42.33 (x86_64-linux) ruby/2.3.0
heroku-cli/4.27.26-693efcb (amd64-linux) go1.6
=== Installed Plugins
heroku-apps@1.2.4
heroku-cli-addons@0.2.1
heroku-fork@4.1.1
heroku-git@2.4.5
heroku-local@4.1.7
heroku-orgs@1.0.4
heroku-pipeline
heroku-pipelines@1.1.1
heroku-run@2.9.2
heroku-spaces@2.0.14
heroku-status@2.1.0

that version of heroku-toolbelt is quite a bit out of date, that could've caused this

Thanks @dickeyxxx for the followup!
