gem install theruraracer -v 0.11.4가 OS X 10.10에서 작동하지 않습니다.

Question

여기에 나와있는 단계를 따라 "gem install therubyracer -v '0.10.2'" on osx mavericks not installing을 실행하면 rbyracer -v 0.10.2와 0.12.0을 설치하면 잘되지만 0.11.4는 얻을 수 없었습니다.

gem install therubyracer -v 0.11.4

결과 :

Answer 1

마침내 theraracer 0.11.4를 설치하고 Xcode 6.1.1, 6.2 베타 또는 6.3 베타 (모두 3 개를 테스트했습니다) 및 Xcode 4.6.3 (사용 가능 : https://developer.apple.com/downloads/index.action)을 사용하여 다음을 실행합니다.

# rename your current version of Xcode to make it distinguishable 
sudo mv /Applications/Xcode.app /Applications/$(xcodebuild -version | head -1 | sed -e 's/ //').app 

# Download and install Xcode 4.6.3 and run: 
sudo mv /Applications/Xcode.app /Applications/Xcode4.6.3.app 

# Switch to your 4.6.3 version of Xcode 
sudo xcode-select --switch /Applications/Xcode4.6.3.app 

# Install the version of libv8 that's tied to your version of TRR: 
gem install libv8 -v '3.11.8.17' 

# Switch back to you original version of Xcode 
sudo xcode-select --switch /Applications/Xcode6.x.app 

# Install TRR 
gem install therubyracer -v '0.11.4'

이 줄이 오류 메시지에 몇 번 나타납니다

It is recommended to use GCC v4.4 or higher 

당신이 수행 한 단계에 대한 링크가있는 것으로 추정를 brew install apple-gcc42를 실행 말한다 GCC 4.2를 설치합니다. 4.2는 4.4 미만입니다. 어떻게 든 메이크 파일을 편집 할 수 있습니다 (또는 extconf.rb) 그 또한 작동 할 수 있습니다, 그 플래그를 제거한다면

C 소스가 생성하는 것을 특정 오류 것 같다 . 그러나 나는 cflags를 수정하는 것이 약간 해킹 된 것 같기 때문에 호환성있는 컴파일러를 설치하는 것이 좋습니다.

Answer 3

이것은 정확히 내가 겪고있는 문제이며, 홈브류 버전을 사용하여 해결했습니다.

문제

보석 libv8을 설치하는 데 문제가있었습니다. 이 문제를 해결하기 위해 brew를 통해 시스템에 v8을 설치 한 다음 --with-system-v8 옵션을 사용했습니다.

$ brew install v8 
$ gem install libv8 -v '3.11.8.13' -- --with-system-v8 
$ gem install therubyracer -v '0.11.4' 

gem libv8이 문제없이 설치되었지만 마지막 줄에 원래 질문의 오류가 발생했습니다. 나는 그 다음 시도했다,

$ gem install therubyracer -v '0.11.4' -- --with-system-v8 --with-v8-dir=/usr/local/Cellar/v8/3.30.33.16 

brew에서 제공하는 v8을 가리킨다. 이 경우 오류가 변경되었으며 지금은과 호환되는 v8 버전을 제공하지 않는다고 말했습니다. 오류 메시지를 검색하는 사람들을 위해

: 나는 V8의 이전 버전을 설치하기로 결정

솔루션. 브루 잉을 다시 사용하여

$ brew search v8 
homebrew/versions/v8-315 v8 
$ brew install v8-315 
$ brew info v8-315 
$ gem install therubyracer -v '0.11.4' -- --with-system-v8 --with-v8-dir=/usr/local/Cellar/v8-315/3.15.11 

이 방법이 효과적입니다. 설치가 끝난 v8 버전은 ~ 3.15이지만 호환이 가능합니다. 3.11.8

실제 해결책은 모든 것을 최신 버전으로 업데이트하는 것입니다. 오래된 보석을 오래 사용하는 것을지지하지 않습니다. 시스템이 손상된 경우에도 깨끗하고 최신 상태로 유지하십시오!
