Missing symbol when installing ruby-2.3.0 on OS X

问题:

I was failing to install ruby-2.3.0 by rvm, while it worked with ruby-2.2.0.

The error message is as below

Error running '__rvm_make -j 1',

There has been an error while running make. Halting the installation.

/usr/lib/libSystem.B.dylib is where it is...

Is there any way to fix it?

回答1:

I had the same problem with Ruby 2.3.1 (El Capitan). The good news I solved it. :-)

I followed the installation tutorial on this page: https://gorails.com/setup/osx/10.10-yosemite

After the first step:

brew install rbenv ruby-build

There is a message like: "Install the XCode Command Line Tools." Maybe they need to be reinstalled after updating XCode.

Like suggested, run:

sudo xcode-select --install

After that the Build and Install of Ruby worked for me.

The answer above suggests to use brew install rbenv ruby-build. I did not have to. Since I do iOS development, I had Xcode installed. But apparently that does not install the xcode command line tools. So I just had to run the following first:

xcode-select --install

I think the linked answer is relevant, my code worked after running the command:

pip install 'pillow!=5.1.0'
