安装gem时出错：无法为cygwin的堆保留空间，Win32错误487 [英] Error installing gem: Couldn't reserve space for cygwin's heap, Win32 error 487

问题描述

我试图在我的机器上安装 win32-api gem，并且在构建本机扩展时遇到一些问题：

  $ gem install win32-api --no-ri --rdoc 
临时增强PATH以包含DevKit ... 
构建本机扩展。这可能需要一段时间... 
 C：\Programs\dev_kit\bin\make.exe：***无法为cygwin的堆预留空间，Win32错误0 
错误：安装win32-api时出错：
错误：无法构建gem原生扩展。 
 
c：/Programs/ruby/bin/ruby.exe extconf.rb 
检查strncpy_s（）... no 
创建Makefile 
 
 make 
 0 [main] us 0 init_cheap：VirtualAlloc指针为null，Win32错误487 
 AllocationBase 0x0，BaseAddress 0x60E90000，RegionSize 0x170000，State 0x10000 
 C：\Programs\dev_kit\bin \make.exe：***无法为cygwin的堆保留空间，Win32错误0 
  

这个问题发生在安装试图编译本地扩展的任何gem时，例如json或win32-api。

我已经尝试更改虚拟内存的大小这台机器，但它没有工作。

我的配置：

• Ruby版本：1.8.7p371


• Gem版本：1.8.24
  Bash 3.1.0


• DevKit 4.5.2
  
• Windows 7 x64

解决方案

很多搜索和许多不同的尝试，这是为我修复它：

1. 下载 rebase 来自 http://www.tishler.net/jason/software/rebase/（下载最新的* .exe版本）并运行它。 启动提示（以管理员身份运行）并转到 dev-kit 文件夹（例如，我的 C：\Programs\dev_kit ）




2. 在dev-kit文件夹中，运行 devkitvars.bat 将devkit添加到路径中。




3. 现在做一个 cd bin （它让我到 C：\Programs\dev_kit\\ bin ）并从那里运行：
   
   

     rebase -b 0x30000000 msys-1.0.dll 
     

尝试再次安装宝石。现在，您应该看到构建本机扩展，而不是看到错误消息。这可能需要一段时间... ，它会在那里挂起一段时间。

您的宝石应该在几分钟/秒后成功安装。没有更多的头痛：）

I'm trying to install win32-api gem on my machine and I'm facing some issues when building native extensions:

$ gem install win32-api --no-ri --rdoc
Temporarily enhancing PATH to include DevKit...

C:\Programs\dev_kit\bin\make.exe: *** Couldn't reserve space for cygwin's heap, Win32 error 0

This problem happens when installing any gem that tries to compile a native extension, like json or win32-api, for instance.

I already tried to change the size of virtual memory of this machine, but it didn't work.

My configuration:

• Ruby version: 1.8.7p371
• Gem version: 1.8.24
• Bash 3.1.0
• DevKit 4.5.2
• Windows 7 x64

解决方案

I was facing the exact same issue and after making a lot of searches and many different tries, this is what fixed it for me:

1. Download rebase from http://www.tishler.net/jason/software/rebase/ (download the latest *.exe version) and run it.

2. Fire up a Prompt ("Run as administrator") and go to your dev-kit folder (for instance, mine was C:\Programs\dev_kit)

3. While in the dev-kit folder, run devkitvars.bat to add devkit to the path.

4. Now do a cd bin (it got me to C:\Programs\dev_kit\bin) and from there run:

   rebase -b 0x30000000 msys-1.0.dll
   

Try to install the gems again. Instead of seeing an error message, now you should see Building native extensions. This could take a while... and it will hang for a while there.

Your gem should be successfully installed after a couple of minutes/seconds. No more headaches :)
