TL;DR

The most likely fix is to install the typescript-language-server executable and ensure it is available in the system's PATH.

Guidance

1. Verify the absence of typescript-language-server: Check if typescript-language-server is installed and available in the system's PATH by running the command which typescript-language-server in the terminal. If it's not found, proceed to the next step.
2. Install typescript-language-server: Install the typescript-language-server using a package manager like npm by running the command npm install -g typescript-language-server or yarn global add typescript-language-server.
3. Update the system's PATH: Ensure the directory where typescript-language-server is installed is included in the system's PATH environment variable. This may require restarting the terminal or running source $HOME/.bashrc (or equivalent) to apply the changes.
4. Retry the operation: After installing typescript-language-server and updating the PATH, retry the operation that previously failed to see if the issue is resolved.

Example

No code snippet is necessary for this issue, as it involves installing and configuring an executable.

Notes

The provided error messages consistently indicate that the typescript-language-server executable is not found in the system's PATH. Installing the executable and ensuring it is accessible should resolve the issue. However, if the problem persists, further investigation into the specific Opus configuration or environment may be necessary.

Recommendation

Apply the workaround by installing typescript-language-server and updating the system's PATH, as this directly addresses the error messages provided.
