Hi Luis,

Thank you for the report. That’s weird.
I need to reproduce the issue. Can you please share the reproduction Markdown code?
Have you installed any other plugins?

[anon66889901]

Hello Takuya
Thank you for your response. I tried the example in the Plugin-description.

$$
\int_0^\infty \frac{x^3}{e^x-1}\,dx = \frac{\pi^4}{15}
$$

I don’t have any other Plugins installed.

Thanks for the reproduction code. I’ve tried to reproduce it but can’t at the moment.

Can you please show me the error stack in the Developer Console? You can toggle it by Developer → Toggle Developer Tools from the menu. Please don’t forget to expand the stack.

Looks like you are on v5.4.3, which is the old version. Please try updating it to the latest version and try again.

[anon66889901]

I downloaded the new Version and still see the Error code.
Here are some Screenshots of the Developer Console:

Thanks for the information. Looks like the package react-katex is loaded from somewhere under your home directory /Users/luisgjokaj/...:

So perhaps you’ve installed that package globally via npm, which is incompatible with Inkdrop.
Can you please try uninstalling it?

[anon66889901]

I just uninstalled the package. It still does not work.

[craftzdog (Takuya Matsuyama)]

Now what does the error stack look like?

[anon66889901]

I thought i uninstalled it, but it looks like its still here.
I used npm uninstall -g @matejmazur/react-katex
I also used npm uninstall -g katex
and npm uninstall -g react-katex

Are these the wrong commands?

[craftzdog (Takuya Matsuyama)]

Yeah looks like it’s still there: /Users/luisgjokaj/Li...st/react-katex.js
You can search those files and remove them manually with rm -r command.

[anon66889901]

I tried this now. This is the new Error Stack:

[craftzdog (Takuya Matsuyama)]

What is index.tsx in the stack? It is nothing to do with the math plugin, so I don’t know why it’s loaded. Let me know the full path of it. You can click it to see its content.

I was having the same issue, I fixed it with the following:

1. quit inkdrop (⌘Q)

2. rm -r /Users/$USER/Library/Application Support/inkdrop/packages/math

3. npm uninstall react-katex

4. ipm install math

Open up inkdrop and hopefully it works

[craftzdog (Takuya Matsuyama)]

Thanks for the info!
The math plugin is using @matejmazur/react-katex instead of the original react-katex package. So, I don’t know why it is something to do with the issue

[anon66889901]

Hello George and Takuya
I just tried what you recommended and it still does not work.
Here the Error stack:

[craftzdog (Takuya Matsuyama)]

You still have react-katex under your home directory:

Does that mean ipm installs react-katex in your home directory? Can you please tell me the exact path of that? I’m confused.

[anon66889901]

complete Path:
/Users/luisgjokaj/Library/Application Support/inkdrop/packages/math/node_modules/@matejmazur/react-katex/dist/react-katex.js

[craftzdog (Takuya Matsuyama)]

Got it. I guess you have the react package installed globally at a path something like /Users/luisgjokaj/node_modules/react:

So, there are duplicate React instances that cause the error.
Can you please try uninstalling it?

[anon66889901]

I just uninstalled react from node_modules and it seems like this was the problem that was causing the error. THANK YOU very much Takuya for your time and your help.

[craftzdog (Takuya Matsuyama)]

Great! Thanks for your report as well!
