Failed to login. Message: undefined is not an object (evaluating 'is_stream_1.default.readable')

[ry24aai-herts-ac-uk]

What happened?

I am unable to login via browser after updating to latest version of gemini-cli 0.3.4 after using API based login, responses are exhausting much faster than actual browser based login

I am using
Ubuntu 24.04
Python 3.12.11
Bun 1.2.18

(node npm alternative)

I have attached screenshots from both browser and terminal

Failed to login. Message: undefined is not an object (evaluating 'is_stream_1.default.readable')

Gemini-CLI not logging in via browser after updating to latest version error message in terminal is pasted as title of the issue Failed to login. Message: undefined is not an object (evaluating 'is_stream_1.default.readable')

while API based login works but credits exhaust much faster

### Anything else we need to know?

_No response_

[gemini-cli]

User is unable to log in via the primary browser authentication method after updating to the latest version. This is a high-priority bug as it affects a core functionality, even though an alternative (API key) login method exists.

I had this issue with bun. Fixed it by switching to npm to install.

@ry24aai-herts-ac-uk What installation method did you use? And are you still experiencing this on latest?

@hjaber were you consistently seeing this with bun?

Still broken after trying latest with bun install -g @google/gemini-cli@preview and trying to authenticate

but npm install -g @google/gemini-cli@preview works
