Question

尝试使用命令部署旧项目时出现问题：

ruby脚本/服务器-e production -p 999

结果：

我的版本是：

Ruby -v

D:\InstantRails\rails_apps\TestManager>ruby -v
ruby 2.3.1p112 (2016-04-26 revision 54768) [x64-mingw32]

Gem -v

2.6.7

iconv gem安装的结果：

gem install iconv - --with-iconv-include = D：/ iconv / include --with-iconv-lib = D：/ iconv / lib

结果：

    Temporarily enhancing PATH to include DevKit...
Building native extensions with: '--with-iconv-include=D:/iconv/include --with-iconv-lib=D:/iconv/lib'
This could take a while...

Could not create Makefile due to some reason, probably lack of necessary
libraries and/or headers.  Check the mkmf.log file for more details.  You may
need configuration options.

Provided configuration options:
        --with-opt-dir
        --without-opt-dir
        --with-opt-include
        --without-opt-include=${opt-dir}/include

To see why this extension failed to compile, please check the mkmf.log which can be found here:

  D:/InstantRails/ruby/lib/ruby/gems/2.3.0/extensions/x64-mingw32/2.3.0/iconv-1.0.4/mkmf.log

extconf failed, exit code 1

Gem files will remain installed in D:/InstantRails/ruby/lib/ruby/gems/2.3.0/gems/iconv-1.0.4 for inspection.

Answer 1

好像你没有安装iconv gem 查看类似的question。

Answer 2

您可能缺少适用于Windows的Devkit：http://rubyinstaller.org/add-ons/devkit/

另请注意，您应该在安装ruby的同一个arch中安装devkit（即：两个64位版本） - ppl经常安装一个32和一个64版本，这也会导致错误。

祝你好运
