Can not download python language server

finntenzor commented 3 years ago

Issue Type: Performance Issue

Open VSCode
Open any python project
Download failed

It's really weird. I CAN download this file with any other tool with relatively reasonable speed(20~100KB/s, in China). But it always failed download with VSCode.

I don't think this is just a network issue. Because I can download this file normally using other tools, but this always fails in VSCode. I think it has to do with VSCode's strategy and approach to downloading files.

Thanks for your feedback! We have recently released a new and more performant language server called Pylance which likely solves these issues you are reporting. You can download Pylance from the marketplace and install it alongside the core Python extension. Because our team's development efforts have shifted to support the new language server, we'd encourage you to try it out.

In the meantime, I'll transfer this issue over to the Microsoft Python Language Server repo for tracking. If you try out Pylance and this issue persists, you can open an issue on the pylance-release repo.

Thank you! I'm excited to try out Pylance.

I hadn't noticed that there was a configuration option that allowed me to select the language server.

A piece of advice for the other guys: Find "Python: Language Server" with "@ext:ms-python.python" and then select "Pylance", or Pylance will not enable (even if you install the extension). In fact, it solved my download problem immediately.
