After installing the 'C/C++' extension from Anysphere, 'PlatformIO IDE' is not activated

Bug Reports

Hello!
I have a problem! After installing the ‘C/C++’ extension from Anysphere, ‘PlatformIO IDE’ is not activated, here is the message “Cannot activate the ‘PlatformIO IDE’ extension because it depends on the ‘C/C++’ extension from ‘Anysphere’, which is not installed. Would you like to install the extension and reload the window?”.
I have installed and deleted Cursor a hundred times, but the problem does not go away, everything was fine with C/C++ from Microsoft before, I use the latest version of Cursor. What should I do?

Please help, I can’t work in the platformIO. This application is not activated. Maybe someone can install the platformIO and write here, is there the same error as me?

Hi all – thanks for raising this issue. I have submitted a PR to Platformio to fix it in their upstream repository: Fix compatibility with editors where MS Cpptools is not supported by ravirahman · Pull Request #4312 · platformio/platformio-vscode-ide · GitHub

In the meantime, we have forked their extension and republished it in Cursor. Could you uninstall the existing one and search for @id:anysphere.platformio-ide? This one removes the dependency on the unavailable cpp extension. Attaching a screenshot

Hi! Very strange behavior: after installing the extension “from scratch” the .platformio directory is empty.

Hello! Please tell me if there will be a solution to this error?

Hi All, thanks for sharing this bug report. We’re looking into it and will share more once we have a fix.

That work arround has gone, I think because the latest version from yesterday.
I work on Ubuntu updated everything but still have the problem.

Cannot activate the ‘PlatformIO IDE’ extension because it depends on the ‘C/C++’ extension from ‘Anysphere’, which is not installed. Would you like to install the extension and reload the window?

Ok got solution:
open /home/■■■/.cursor/extensions/platformio.platformio-ide-3.3.4-linux-x64/package.json

search for “extensionDependencies”

change to “extensionPack”

should look like that:

	"webpack-cli": "~6.0.1"
	},
	"extensionPack": [
		"ms-vscode.cpptools"
	],
	"__metadata": {

have fun

Hi all – we will have a permanent fix for this in the next update to the Cursor client. In the meantime, I would recommend the workaround that @JoergSH identified to manually monkey-patch the extension.

This is important to me as a paid user to Cursor.

I switched from Windsurf to Cursor, and I need PlatformIO.

Do Not Break PlatformIO, please.

Windsurf worked with PlatformIO via the manual .vsix install trick, but I didn’t have to do any other monkeypatching.

And on Windows, the file to modify is here:
%USERPROFILE%.cursor\extensions\platformio.platformio-\package.json

It works fine by renaming “extensionDependencies” by extensionPack".
