试用了下heroku，结果安装时就出问题了
windows环境，按照
http://docs.heroku.com/windows 装了
msysgit和
1.8.6 one click ruby installer
D:\Ruby>gem install heroku
ERROR: While executing gem ... (Gem::RemoteFetcher::FetchError)
timed out (http://gems.rubyforge.org/gems/json_pure-1.2.0.gem)
大概是网络不行，于是下载后本地安装
D:\Ruby>gem install "C:\Documents and Settings\wli\My Documents\Downloa
ds\heroku-1.8.0.gem"
ERROR: While executing gem ... (URI::InvalidURIError)
bad URI(is not URI?): C:/Documents and Settings/wli/My Documents/Do
wnloads/heroku-1.8.0.gem
不行
D:\Ruby>gem install C:\Documents and Settings\wli\My Documents\Download
s\heroku-1.8.0.gem
ERROR: could not find gem C:\Documents locally or in a repository
ERROR: could not find gem and locally or in a repository
ERROR: While executing gem ... (RegexpError)
Invalid escape character syntax: /\ASettings\wli\My\Z/
还是不行，猜测是路径空格的问题
D:\Ruby>gem install E:/json_pure-1.2.0.gem
Successfully installed json_pure-1.2.0
1 gem installed

OK，成功
如此
