如何在10.10 Yosemite上安装therubyracer gem？

Question

我无法在Yosemite 10.10上安装therubyracer gem.

这是日志:

and *not* the one that is bundle with the libv8 rubygem. However,
it could not be located. please make sure you have a version of
v8 that is compatible with 3.16.14.3 installed. You may
need to special --with-v8-dir options if it is in a non-standard
location

Gem files will remain installed in /usr/local/var/rbenv/versions/2.1.2/lib/ruby/gems/2.1.0/gems/therubyracer-0.12.1 for inspection.
Results logged to /usr/local/var/rbenv/versions/2.1.2/lib/ruby/gems/2.1.0/extensions/x86_64-darwin-14/2.1.0-static/therubyracer-0.12.1/gem_make.out

Answer 1

gem uninstall libv8
brew install v8
gem install therubyracer
gem install libv8 -v '3.16.14.3' -- --with-system-v8

这是它在10.10上的唯一方式(ruby 2.1.2)

或者尝试gem install libv8 -v 'XX.XX.XX' -- --with-system-v8添加gem的版本:)

Answer 2

git clone https://github.com/cowboyd/libv8.git
cd libv8
bundle install
bundle exec rake clean build binary
gem install pkg/libv8-3.16.14.3-x86_64-darwin-12.gem #note that libv8 version may change, so tab through files in pkg/, also remember to use the one with version specified

然后只是捆绑你的项目宝石

这是它在10.10上的唯一方式(ruby 2.1.2)

Answer 3

这次没有一个答案对我有用.我也用过这个:

brew tap homebrew/versions
brew install v8-315

gem install libv8 -v '3.16.14.13' -- --with-system-v8
gem install therubyracer -- --with-v8-dir=/usr/local/opt/v8-315

bundle install

看到红宝石Github问题.

希望它可以帮助别人.

Answer 4

也许它会对某人有用但我在安装therubyracer时遇到问题(因为libv8存在问题)解决方案是卸载我安装的所有libv8.安装therubyracer

$ gem uninstall libv8
$ gem install therubyracer -v '0.12.0'
Fetching: libv8-3.16.14.7-x86_64-darwin-14.gem ( 57%)

我希望这可以帮助别人.

Answer 5

看起来这已经在上游修复了.对我和@aurels以及@Mike Causer和@Juanda有用的是:

bundle update libv8

Answer 6

这对我的Yosemite和Ruby 2.1.5(Ruby通过RVM)非常有用.

gem install libv8 -v '3.16.14.3' -- --with-system-v8

之前它给了我Gem::Ext::BuildError: ERROR: Failed to build gem native extension.libv8 gem版本3.16.14.3的错误

Answer 7

我之后能够继续使用红宝石赛车 rm Gemfile.lock

事先:我安装了v8 brew install v8,然后做了gem install libv8 -v '3.16.14.3' -- --with-system-v8

我正在跑10.10优胜美地

Answer 8

只有这在我的Yosemite,Ruby 2.1.2中适合我:

gem install libv8 -v '3.16.14.3' -- --with-system-v8
brew link --overwrite v8-315 --force
gem install therubyracer -v '0.12.2' -- --with-system-v8
