CLI Version

2.36.2

Operating System and Architecture

Operating System Version

macOS Sonoma 14.6.1 (23G93)

Link to reproduction repository

No response

CLI Command

./sentry-cli uninstall

Exact Reproduction Steps

Checkout your app's source code, as you would on a CI server such as Jenkins
Install sentry to the current directory using the install script hosted at https://sentry.io/get-cli/
Attempt to uninstall or upgrade sentry-cli using ./sentry-cli update or ./sentry-cli uninstall

touch package.json
curl -sL https://sentry.io/get-cli/ | INSTALL_DIR="." SENTRY_CLI_VERSION="2.36.2" bash
./sentry-cli update
./sentry-cli uninstall

Expected Results

The upgrade or uninstall command succeeds, since sentry-cli is not mentioned anywhere in package.json.

Actual Results

Upgrade and uninstall fail with the following message:

Please use npm/yarn to update sentry-cli, using one of the following commands:
  yarn upgrade @sentry/cli
  yarn global upgrade @sentry/cli
  npm update @sentry/cli
  npm update -g @sentry/cli

This line checks for the existence of package.json, without checking if sentry-cli is actually included in the file:

sentry-cli/src/utils/system.rs

Line 43 in 1299e69

Ok(exe.is_file())

@jasondentler thanks for reporting this bug! Probably the most reliable way to fix this would be to distribute a different binary (e.g. using the managed feature) to npm so that we don't have to guess at runtime how the Sentry CLI was installed
