Question

我按照这些说明尝试在Mac Lion上构建V8： http://code.google.com/apis/v8/build.html

我收到此错误：

    $ scons sample=shell mode=release snapshot=on
scons: Reading SConscript files ...
OSError: [Errno 2] No such file or directory:
  File "/Users/pottmi/Tools/v8/v8-read-only/SConstruct", line 1569:
    Build()
  File "/Users/pottmi/Tools/v8/v8-read-only/SConstruct", line 1517:
    opts = GetOptions()
  File "/Users/pottmi/Tools/v8/v8-read-only/SConstruct", line 1153:

  File "/Users/pottmi/Tools/v8/v8-read-only/SConstruct", line 1137:

    None
  File "/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/subprocess.py", line 1202:
    None

以下是我安装的软件版本：

svn, version 1.6.17 (r1128011)
Python 2.7.1
SCons by Steven Knight et al.:
        script: v2.1.0.r5357[MODIFIED], 2011/09/09 21:31:03, by bdeegan on ubuntu
        engine: v2.1.0.r5357[MODIFIED], 2011/09/09 21:31:03, by bdeegan on ubuntu
        engine path: ['/usr/local/lib/scons-2.1.0/SCons']

/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/路径存在，但没有subprocess.py文件。

我认为构建v8的推荐方法是使用gyp。有关以这种方式构建它的信息，请参阅http://code.google.com/p/v8/wiki/BuildingWithGYP。

在过去的两年中，使用Homebrew比使用手动编译更好运。通过Homebrew安装v8 Javascript引擎非常简单：

[12:26] Bryson@Galactica  ~ :$ brew install v8
==> Installing v8 dependency: scons
==> Downloading http://downloads.sourceforge.net/scons/scons-2.2.0.tar.gz

/usr/local/Cellar/v8/3.9.24: 12 files, 5.8M, built in 55 seconds

安装Dependancies，检查版本等。从这里开始，只需输入v8即可进入shell。
