问题描述
我正在关注Michael Hartl的教程,如果它是有助于回答这个问题。
首先我安装Cygwin64,然后我下载rubygems-2.3.0。我将rubygems-2.3.0移动到C:\cygwin64\home\mycomputername。我解开它成功,cd进入rubygems-2.3.0文件夹,并运行setup.rb。
当我运行命令gem install rails --version 3.0.0,它安装成功,直到我到达
p> Fetching:rack-1.2.8.gem(100%)
错误:执行gem ...(TypeError)时
无法转换nil into String
这是上述错误发生的地方。在这之后,没有rails命令将工作。
我应该注意,我的版本的ruby是v1.9.3,如果有意义。
我建议您从(如果您使用的是Windows 7)。
I'm trying to install ruby on rails for windows 7. I've tried this on Professional and Enterprise.
I'm following Michael Hartl's tutorial if it helps answer this question.First I install Cygwin64, then I download rubygems-2.3.0. I move rubygems-2.3.0 into C:\cygwin64\home\mycomputername. I untar it successfully, cd into the rubygems-2.3.0 folder, and run setup.rb.Everything works fine up till here.
When I run the command gem install rails --version 3.0.0, it installs successfully until I get to
Fetching: rack-1.2.8.gem (100%)ERROR: While executing gem ... (TypeError) can't convert nil into String
Which is where the above error happens. After this, no rails command will work.
I should note that my version of ruby is v1.9.3, if it matters.
I suggest you install Ruby and Rails from http://railsinstaller.org/en if you are on Windows 7.
