问题描述
我正在尝试在 cygwin (windows7) 上运行 Rails 入门博客.我收到以下错误消息:
I am trying to run the Getting Started with Rails blog on cygwin (windows7). I get the following error message:
ExecJS::Welcome#index 中的运行时错误
ExecJS:: RuntimeError in Welcome#index

throw err;
^

节点已安装.
这是在
$rails generate controller welcome index
$rails s
我在 cygwin 上运行 Rails 4.0知道为什么会发生这种情况吗?

推荐答案
我遇到了这个错误,它与临时文件的路径错误有关.我能够通过更改 \gems\[ruby version]\gems\execjs-2.0.2\lib\execjs
中的以下两个文件来修复它.(可能在 \usr\lib\ruby\
中找到,但这取决于您的 Ruby 的安装方式.我使用的是 RVM,所以我的不同.)
I encountered this error and it had to do with the path to the temp file being wrong. I was able to fix it by changing the following two files in \gems\[ruby version]\gems\execjs-2.0.2\lib\execjs
.
(Possibly found in \usr\lib\ruby\
, but that depends on how your Ruby is installed. I'm using RVM so mine is different.)
compile_to_tempfile(source) do |file|
extract_result(@runtime.send(:exec_runtime, file.path))
end
end
应该改为
compile_to_tempfile(source) do |file|
filepath = file.path
if ExecJS.cygwin? && @runtime.name == "JScript"
IO.popen("cygpath -m " + file.path) { |f| filepath = f.read }
filepath = filepath.gsub("\n","")
end
extract_result(@runtime.send(:exec_runtime, filepath))
end
end
module.rb
在最后两个 end
之前添加这个.
def cygwin?
@cygwin ||= RbConfig::CONFIG["host_os"] =~ /cygwin/
end
在这之后重启你的 Rails 服务器,幸运的话它应该可以工作了.
After this restart your Rails server and with any luck it should work.
