PlatformIO IDE extension is not found in the Marketplace

Here are two temporary fixes until Cursor be installed from the marketplace:

  • Install from VSIX file
  1. Download and install VS Code (if you haven’t already)

  2. Launch VS Code and navigate to the extensions marketplace in the sidebar

  3. Search for what ever extension you need (in this case you will need to install both the PlatformIO IDE and C/C++ extensions)

  4. Click on the settings button and then the Download VSIX button (or a specific version if you want)

  5. You will be prompted to pick a version for your specific OS and architecture, and also a download location (you can put it in your downloads folder.)

  6. Now to install the extension, launch Cursor, open the command palette (Ctrl + Shift + P) and search and run the “install from VSIX“ command

  7. After running the command, you should be prompted to select the VSIX extension file to install.

  8. To get the PlatformIO IDE extension working in Cursor, you will also have to install the C/C++ extension. Repeat these steps for both extensions if you are planning on using Platform IO IDE. Note: You may have to uninstall the Anysphere C/C++ extension to install the Microsoft version in Cursor.

  • Import extensions and settings from VS Code
  1. If you find it easier to just transfer everything over from VS Code, you can do so. First open Cursor settings (gear icon in top right corner)

  2. Press the “Import Settings from VS Code“ button and follow the prompts (Note: this will override all of your settings, extensions, and keybindings that you already have configured. If you want to keep these, follow the first method)

I hope this helps.
