read-only variable: ZVM_NAME

[mskar]

What does this mean?

~/.zsh-vi-mode/zsh-vi-mode.zsh:100: read-only variable: ZVM_NAME

How can I avoid this message upon shell startup?

Hi @mskar

Could you provide the instructions about how you loaded this plugin? Especially, the context around the source line.

Thanks and regards

[mskar]

I cloned and sourced the plugin:

git clone https://github.com/jeffreytse/zsh-vi-mode.git $HOME/.zsh-vi-mode
source $HOME/.zsh-vi-mode/zsh-vi-mode.plugin.zsh

I think I will have to use the process of elimination to see which line(s) in my .zshrc is/are causing the problem.

Hi @mskar

👍 You are right, to use the process of elimination to see the problem. Any progress, please share to here, in case of it could help other people.

Thanks and regards

I'm also having this issue. Get this on the terminal when I run source
~/.oh-my-zsh/custom/plugins/zsh-vi-mode/zsh-vi-mode.zsh:105: read-only variable: ZVM_NAME

Line 105 of zsh-vi-mode.zsh is below:
typeset -gr ZVM_NAME='zsh-vi-mode'

It seems that ZVM_NAME cannot be set for some reason.

Could it be an OS-specific issue?
@GerardKetuma, do you also use MacOS?
What if we remove the -r option from line 105?
typeset -g ZVM_NAME='zsh-vi-mode'
https://opensource.apple.com/source/zsh/zsh-65/zsh/Doc/help/typeset.auto.html
If that doesn't work, maybe we can use export instead of typeset to set ZVM_NAME?

@mskar Yes, I'm using Mac OSX.

Tried removing the -r option but still got the same error.

Hi, @GerardKetuma @mskar

Many thanks for you guys reporting this issue and I'm so sorry for the inconvenient. Could you provide more details for me to dig this problem? Currently I have no way to reproduce it.
