Error update plugins (Deprecation warning)

[VincentLanglet]

• I am on the latest Hyper.app version
• I have searched the issues of this repo and believe that this is not a duplicate

• OS version and name: Mojave 10.14.4
• Hyper.app version: Just installed
• Node version: 12.4.0
• Npm version: 6.9.0
• Yarn version: 1.16.0

Issue

Everytime i launch the terminal I get a message
Deprecationwarning Buffer() is deprecated due to security and usability issue

I look for Error update plugins in the issues but didn't find one about the deprecation warning message.

Duplicate of #3595

[IgorGanapolsky]

This issue is still occurring now in Hyper 3.0.2 (stable)

[andreaspabst]

Still there

[calexandre]

Happening to me aswell. Running 3.0.2 (stable)

[VincentLanglet]

Since the issue #3595 is close, I reopen this one.

Had the same issue but fixed it by doing this:

1. Remove all plugins from .hyper.js and do a full reload
2. Add the plugins back and reload again

Adding proxies for yarn in my .zshrc solved the issue for me:

# yarn config for hyper
yarn config set proxy $http_proxy --silent
yarn config set https-proxy $http_proxy --silent
yarn config set no-proxy $no_proxy --silent 
yarn config set strict-ssl false --silent

For me this was an issue with Yarn trying to use a proxy for some reason (yarnpkg/yarn#4890). I don't use yarn so I didn't know it wasn't working. You can try running the 'yarn' command manually in your '.hyper_plugins' folder to see if that's the issue. Yarn gave me more helpful error messages than Hyper did.

e.g.

cd ~/.hyper_plugins
yarn

You can see if yarn has a proxy set by running:

yarn config list

These commands eventually fixed it for me:

yarn config delete https-proxy
yarn config delete proxy
yarn config set no-proxy true

@danacr 's suggestion worked for me, I presume then (as I also tried @drdogbot7 's solution) that strict-ssl = false might have been the source of my flag.

Fresh install of macOS, Hyper 3.0.2 stable installed and this issue is occurring for me as well.

hyper -v shows a longer version of the notification message.

[Notification] Error updating plugins.: (node:88731) [DEP0005] DeprecationWarning: Buffer() is deprecated due to security and usability issues. Please use the Buffer.alloc(), Buffer.allocUnsafe(), or Buffer.from() methods instead.

@marjorg's suggestion didn't work for me.

Don't have yarn installed so the other suggestions just cause more errors.

---

Update - reluctantly installed yarn, ran the commands in @drdogbot7's comment and this has fixed the issue for me.

I didn't plan on using yarn so I've removed it now and the error has not returned.

brew uninstall yarn

If you have a pretty clean set of homebrew install you may also be able to uninstall yarn's dependencies.

Find the dependencies:

brew deps yarn

Uninstall the ones you don't need, for me this was:

brew uninstall node
brew uninstall icu4c

@drdogbot7's suggestion worked for me, but I had to install yarn from brew. For some reason, installing it with npm: npm i -g yarn didn't work :( Either way, glad I figured it out and thanks to everyone from this thread!

Commands that worked for me:

brew install yarn
cd ~/.hyper_plugins
yarn
yarn config delete https-proxy
yarn config delete proxy
yarn config set no-proxy true

I had this issue (twice - once for my mac mini m1 and once for my macbook air m1)
For me it was a permissions problem. I noticed that because every time I had to do a npm install / yarn add I got EACCES permission denied, I had to sudo everything - turns out that this was also messing up the ability of hyper to install plugins as well.

try doing this:

chown -R yourusername /users/yourusername

that solved the above issues I was having on my m1 mac
