use*_*003 73 ruby gcc therubyracer libv8 osx-mavericks
我正在尝试在Mavericks上安装以下gem版本
显然,therubyracer宝石取决于libv8.
什么是libv8?我的一些研究似乎表明它是Google Chrome使用的某种javascript库?
我在安装它时遇到了麻烦,但是这个很棒的帖子既有我的错误,也有关于如何绕过它的解释清楚的答案.
所以我安装libv8
了
gem install libv8 -- --with-system-v8

这是我的理解,这安装了gem,但使用我的本地系统安装v8库而不是... gem附带的版本?无论哪种方式,它都是成功的.
在下一步中,我在安装therubyracer
gem时遇到了麻烦.我不太确定这个gem是做什么的,只是因为它是我正在尝试的rails项目的依赖项bundle install
.
它给了我以下错误:
Gem::Ext::BuildError: ERROR: Failed to build gem native extension.

从我可以收集的内容来看,我选择libv8
使用我的本地V8库而不是提供的内容进行安装libv8
,但现在无法找到本地安装.
extconf.rb
?我在几个地方见过它.它gcc
在具体的编译器中尝试做什么?谢谢!!

这些步骤对我有用.
操作系统:Maverick Ruby:2.1.1
gem uninstall libv8
gem install therubyracer -v '0.11.3'
gem install libv8 -v '3.11.8.13' -- --with-system-v8

对于那些在OS X El Capitan中遇到此问题的人来说,来自therubyracer问题线程的这个解决方案最终对我有用:
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

我之前也跑过brew install gcc
,但我不确定这是否真的有必要.

首先尝试卸载libv8 gem,然后安装rubyracer,再安装libv8
gem uninstall libv8
gem install therubyracer
gem install libv8 -- --with-system-v8

在尝试了相应github问题和此处提出的所有其他解决方案后,Tertom 在github上发布的解决方案为我解决了这个问题.
我有完全相同的系统配置.
这是el capitan,所以不是问题的确切答案,但人们可能会发现此信息有用.
我在这里引用它的可见性:
解决了同样的问题
- MacOS 10.11.2
- 红宝石1.9.3
- libv8 3.16.14.13
- therubyracer 0.12.2
-
Run Code Online (Sandbox Code Playgroud)brew tap homebrew/versions brew install v8-315 brew link --force v8-315 bundle install brew unlink v8-315
如果你也无法安装libv8,
Run Code Online (Sandbox Code Playgroud)gem install libv8 --with-system-v8
要么
Run Code Online (Sandbox Code Playgroud)bundle config build.libv8 --with-system-v8

对于所有使用 macOS 10.15 的人来说,brew 已经发生了变化,因此您需要执行这些命令。
brew install v8@3.15
gem install libv8 -v 'YOUR_VERSION' -- --with-system-v8
gem install therubyracer -v 'YOUR_VERSION' -- --with-v8-dir=/usr/local/opt/v8@3.15
bundle install

上述答案对我不起作用; 我的bundler配置已disable-shared-gems
启用,这会导致其他问题.
我正在使用Yosemite 10.10.1,Rails 3.2.x和Ruby 1.9.3p550.
我的以下片段为我bin/setup
解决了这个问题.
if ! bundle show therubyracer; then
bundle config build.libv8 --with-system-v8
gem install --install-dir vendor/bundle libv8 -v 3.16.14.7
gem install libv8 -v 3.16.14.7
gem install --install-dir vendor/bundle therubyracer
