描述

Do you want to request a feature or report a bug? bug

What is the current behavior? Installed yarn has version 0.24.6 instead of 0.27.5 through some package providers (Debian repositories, shell script, npm).

If the current behavior is a bug, please provide the steps to reproduce. docker run --rm -it node "curl -o- -L https://yarnpkg.com/install.sh | bash && yarn --version" outputs the following latest lines:

> Successfully installed Yarn 0.27.5! Please open another terminal where the `yarn` command will now be available.
0.24.6

What is the expected behavior? Last line should output 0.27.5.

Please mention your node.js, yarn and operating system version. From node docker image:

# node -v
v8.1.2
# uname -r
4.9.0-3-amd64
# cat /etc/issue
Debian GNU/Linux 8 \n \l

研究方向
Examine the install script (likely `install.sh`) to understand how it detects and replaces existing yarn installations. The issue shows that after running the script, the old version remains. Focus on the version check and replacement logic. Check the repository's issues and comments for any related discussion or proposed fixes.
