Linguist: Could not gem install github-linguist on Mac OS

[Jingciii]

I tried to execute sudo gem install github-linguist as well as gem install github-linguist --user-install on my Macbook, but both failed with the error messages. My ruby version is 2.3.7.

I have no prior knowledge on Ruby and just wanna use the linguist library. Can anyone help solve this? Thanks

[Jingciii]

@siawash96 Thanks anyway!

I just found out that I only need to add spaces /Library/Developer/CommandLineTools/SDKs/MacOSX10.14.sdk/System/Library/Frameworks/Ruby.framework/Versions/2.3/usr/include/ruby-2.3.0/universal-darwin18/ruby/config.h line 365 and 366 to distinguish between literal and identifiers. This solves my problem.

Guess this is caused by upgrade version of Xcode.

@Jingciii Can we close this then?

[Jingciii]

Sure

Same issue here
IMHO, having the user to fix manually the spaces in some header file (that could be used by anything else for all I know) is not a good workaround

As far as I understand, it's not really an issue on linguist side, but maybe the right compilation options might do the trick ?

@ReyAnthony Yup, I think the flags mentioned at https://github.com/github/linguist/issues/4449#issuecomment-470208078 should do the trick.

It really bugs me that a third party gem requires peeps in an unrelated project to jump through hoops to get it installed. We could document this, but I fear we'll be continually updating our docs as this seems to change ever-so-slightly with almost every release of macOS 😞.

[ProjectBarks]

For those who struggled to understand what needed to be done:

Change line 365-366 to this:

#define RUBY_ARCH "universal-" RUBY_PLATFORM_OS
#define RUBY_PLATFORM "universal." RUBY_PLATFORM_CPU "-" RUBY_PLATFORM_OS

[hudsontavares]

@lildude I would suggest at least the inclusion of these steps in a FAQ or similar.

Not all the users have ever seen make error messages related to header files - so, not all of them will paste the error on Google as I did to find out this issue entry.

I agree that this is not linguist's call, but it ends blocking the usage of this amazing tool for many people.

Thanks @ProjectBarks, for me it was the lines 413-414 👍

[hyeoksuhan]

The file path and lines are depend on my system.
So, it should be checked the path in error message.

In my case the path was /Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.15.sdk/System/Library/Frameworks/Ruby.framework/Versions/2.6/usr/include/ruby-2.6.0/universal-darwin19/ruby/config.h and line was 413-414.

You can run

sudo gem install charlock_holmes -- --with-icu-dir=/usr/local/opt/icu4c --with-cxxflags='-Wno-reserved-user-defined-literal -std=c++11'

and then run

sudo gem install github-linguist
