迁移MacBook后重装rvm执行./configure时遇错误求助

Hey there, I’ve run into this exact combination of issues before—migrating a MacBook, using Fish shell, and trying to install older Ruby versions with RVM. Let’s walk through fixing this step by step:

1. Wipe Existing RVM Residues First #

Migration often leaves behind corrupted or mismatched RVM files. Let’s start fresh:

# Uninstall RVM completely
rvm implode
# Remove leftover system and user RVM files
sudo rm -rf /etc/rvmrc ~/.rvm

Close and reopen your Fish terminal to ensure all traces are gone.

2. Reinstall RVM with Fish Shell Support #

RVM was built for Bash/Zsh, so we need to set it up properly for Fish:
First, install RVM using Bash (since the installer relies on Bash syntax):

bash -c "$(curl -sSL https://get.rvm.io)"

Next, add Fish shell support for RVM. The simplest way is to manually configure your Fish config:
Open ~/.config/fish/config.fish in your favorite text editor and add this line:

source ~/.rvm/scripts/rvm

Reopen your terminal again to load the new RVM configuration.

3. Install Required Dependencies for Ruby 2.3.3 #

Ruby 2.3.3 is an older version that needs specific system libraries to compile on macOS 10.13:

1. Install Xcode Command Line Tools (if not already installed):

xcode-select --install

2. Use Homebrew to install critical libraries (install Homebrew first if you haven’t already):

brew install openssl libyaml libffi

4. Install Ruby 2.3.3 with Correct Library Paths #

The most common failure here is missing OpenSSL support. Tell RVM to use the Homebrew-installed OpenSSL (which is compatible with Ruby 2.3.3):

rvm install 2.3.3 --with-openssl-dir=$(brew --prefix openssl)

This command forces Ruby to compile against the compatible OpenSSL version instead of the system’s outdated one.

5. Fix Permissions (If Issues Persist) #

Migration can mess up file ownership. Ensure you own the RVM directory to avoid permission errors:

sudo chown -R $USER:$GROUP ~/.rvm

Quick Checks to Confirm Success #

After installation, run these commands in Fish to verify everything works:

# List installed Ruby versions
rvm list
# Switch to Ruby 2.3.3
rvm use 2.3.3
# Confirm the correct Ruby version is active
ruby -v

If you still hit errors, dig into the configure.log file you mentioned—look for lines mentioning missing libraries (like OpenSSL) or shell syntax errors (which would point to a Fish configuration issue).
