在 Windows7 64 位上安装 jslint-v8 Ruby gem 的问题 [英] Problems with jslint-v8 Ruby gem installation on Windows7 64-bit
问题描述
在 Windows 7(64 位)上设置 Rally App SDK 2.0p 环境时出现问题.我已经从 rubyinstaller.org 安装了 Ruby 1.8.7-p358 并设法安装了 rake Ruby gem.但我在安装 jslint-v8 gem 时遇到问题.它依赖于需要使用 Ruby DevKit 构建的 therubyracer 和 libv8 gems.在安装过程中出现以下错误:
There is a problem during Rally App SDK 2.0p environment setup on Windows 7 (64-bit). I have installed Ruby 1.8.7-p358 from rubyinstaller.org and managed to install rake Ruby gem. But I have problems installing jslint-v8 gem. It has dependencies on therubyracer and libv8 gems which need to be built using Ruby DevKit. During the installation I got the following error:
C:
uby> gem install jslint-v8

有人知道如何在Win7中正确安装吗?谢谢！
Does anyone know how to install it correctly in Win7? Thank you!
推荐答案
您尝试安装的 gem 依赖于 libv8 gem，它只不过是 Google V8 JavaScript VM 的包装器.
The gem you try to install depends on libv8 gem, which is nothing more than a wrapper for Google V8 JavaScript VM.
没有针对 Windows 的预编译 libv8(就像 Linux 或 OSX 一样)，这意味着它需要从头开始构建 V8.
There is no pre-compiled libv8 for Windows (like there is for Linux or OSX), this means it needs to build V8 from scratch.
围绕V8的构建过程的代码不是很便携，更不用说编译libv8你需要安装Python:-P
The code around the build process of V8 is not very portable, not to mention that to compile libv8 you need Python installed :-P
直到今天，没有人能够按照存储库说明在 Windows 上按照 libv8 预编译的说明进行操作:
Until today nobody was able to follow the instructions for libv8 pre-compilation on Windows, following the repository instructions:
