Ubuntu 18.04安装Ruby 2.1.10时出现'__rvm_make -j4'执行错误求助

Hey there, sorry to hear you’ve been stuck on this frustrating installation issue for a full day—let’s break down some additional fixes that might get you past that __rvm_make -j4 error. The problem usually boils down to missing compile dependencies, incompatible system tools, or resource constraints, so let’s tackle each angle:

1. Install All Required Compilation Dependencies #

You’ve already installed some libraries, but Ruby 2.1.10 (a pretty old version) needs a full set of build tools and dependencies to compile successfully. Run this to cover any gaps:

sudo apt-get update && sudo apt-get install build-essential zlib1g-dev libssl-dev libreadline-dev libyaml-dev libsqlite3-dev sqlite3 libgdbm-dev libncurses5-dev automake libtool bison libffi-dev

2. Clean RVM Cache & Force a Fresh Compilation #

RVM might be holding onto corrupted cached files from your previous attempts. Clear them out and force a source compile (skipping pre-built binaries which can be problematic for older Ruby versions):

rvm cleanup all
rvm install 2.1.10 --disable-binary

3. Use a Compatible GCC Version #

Newer GCC versions (8+) often introduce compatibility issues with older Ruby releases like 2.1.10. Try installing an older GCC version and forcing RVM to use it:

# Install GCC 6 (a safe choice for Ruby 2.1.x)
sudo apt-get install gcc-6 g++-6

# Install Ruby using GCC 6
CC=gcc-6 rvm install 2.1.10

4. Fix Memory Constraints (Common on VMs/Low-RAM Systems) #

The make error can pop up if your system doesn’t have enough RAM to handle the compilation. Add a swap file to give your system extra memory:

# Create a 2GB swap file
sudo fallocate -l 2G /swapfile

# Secure the swap file permissions
sudo chmod 600 /swapfile

# Enable the swap file
sudo mkswap /swapfile && sudo swapon /swapfile

# Now try installing Ruby again
rvm install 2.1.10

5. Manual Compilation (If RVM Still Fails) #

If RVM continues to misbehave, try compiling Ruby from source directly and then registering it with RVM:

# Download the Ruby 2.1.10 source
wget https://cache.ruby-lang.org/pub/ruby/2.1/ruby-2.1.10.tar.gz

# Extract and enter the source directory
tar -xzf ruby-2.1.10.tar.gz && cd ruby-2.1.10

# Configure the build (point to RVM's rubies directory)
./configure --prefix=$HOME/.rvm/rubies/ruby-2.1.10

# Compile and install
make -j4 && make install

# Tell RVM about this installation
rvm use ruby-2.1.10 --default

If none of these work, could you share the full output from the rvm install command (specifically the part right before the __rvm_make error)? That will help pinpoint exactly where the compilation is failing.
