Ruby：堆棧級別太深（SystemStackError）

Question

Ruby在Cygwin中因使用rails和bundler而崩潰。

$ ruby -v
ruby 1.9.3p374 (2013-01-15 revision 38858) [i386-cygwin]

Chloe@dumbopc /cygdrive/c/Sites
$ rails -v
Rails 3.2.11

Chloe@dumbopc /cygdrive/c/Sites
$ cd testapp

Chloe@dumbopc /cygdrive/c/Sites/testapp
$ rails -v

/usr/lib/ruby/gems/1.9.1/gems/bundler-1.2.3/lib/bundler/friendly_errors.rb:32: 
stack level too deep (SystemStackError) 

我嘗試了Ruby的兩個版本：ruby 1.9.3p327和ruby-1.9.3-p374-1。 我從Google找到了一些暗示1.9.2可以解決該問題的信息，但是我無法在setup.exe中選擇它。 我也試過

peflags -x8192000 `which ruby`

這沒有幫助。 我還嘗試了18192000。我卸載了Ruby，然后重新安裝。 與導軌相同。 它只有在應用程序目錄中時才會失敗。 當我嘗試

rails new testapp

它創建目錄和文件，但是在bundle install上失敗。 我也不能在該目錄中運行rails -v 。 我懷疑還有其他命令也會失敗，但是我還沒有找到它們。 我正在使用Windows XP SP3。

$ uname -a

如果您好奇的話，這是壞消息

$ rails -v
/usr/lib/ruby/site_ruby/1.9.1/rubygems/requirement.rb:114: stack level too 
deep (SystemStackError)
$ cat -n /usr/lib/ruby/site_ruby/1.9.1/rubygems/requirement.rb | grep '^ *114'
   114      requirements.map { |op, version| "#{op} #{version}" }.sort
$ bundle install
/usr/lib/ruby/gems/1.9.1/gems/bundler-1.2.3/lib/bundler/friendly_errors.rb:32:

$ cat -n /usr/lib/ruby/gems/1.9.1/gems/bundler-1.2.3/lib/bundler/friendly_errors.rb |  grep '^ *32'
    32        raise e

我還嘗試了bundler鏈接后的所有建議。 我在-rails腳本中添加了-d，並打印了以下內容：

$ head -1 /usr/bin/rails
#!/usr/bin/ruby.exe -d

Answer 1

我認為您的peflags命令行錯誤。 嘗試：

peflags -X409600 `which ruby`

作為描述在這里 。

Answer 2

同樣的事情發生在我身上。 我從cygwin設置文件中卸載了ruby，當我在CMD中打開ruby -v時，它仍然存在！

原來，我在“ PATH”環境變量中還有ruby.exe的其他實例。 因此，請檢查您的環境變量，卸載所有內容，然后查看它是否指向另一個ruby文件。
