升级到 Ruby EE 后，Rails 2.3.8 将无法在 Passenger 上运行 - iconv 错误

Question

我刚刚安装了 Ruby EE 11.01。我有一个 Rails 2.3.8 应用程序，它在 Apache2 上的 Passenger 3.0.2 上运行。现在，我的申请不会出现。错误是：

no such file to load -- iconv

我使用的是 Mac OS X 10.6.4。我安装 Ruby EE 时使用：

sudo ./installer -c --with-openssl-dir=/opt/local -c --with-readline-dir=/opt/local -c --with-iconv-dir=/opt/local

“which iconv”产生：

/opt/local/bin/iconv

尝试安装 gem iconv 产生：

Building native extensions.  This could take a while...
ERROR:  Error installing iconv:
ERROR: Failed to build gem native extension.

/opt/ruby-enterprise-1.8.7-2011.01/bin/ruby extconf.rb
checking for iconv() in iconv.h... no
checking for iconv() in -liconv... no
*** extconf.rb failed ***
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.

安装行中的 iconv 路径是否错误？帮助！

查看上面的日志文件我看到这个：

我强烈建议在 Mac 操作系统上使用 RVM。它的安装非常简单，它可以使用 readline、iconv、openssl、zlib 等来处理下载和编译环境。我无法告诉你它为我节省了多少个小时。

回到你的问题 - 你尝试过gem install iconv -- --with-iconv-dir=/opt/local ？
