如何在 Ubuntu 11.10 上使用 RVM 在 IRB 中获得 Readline 支持

Question

我已经尝试了我能想到的一切方法来使其正常工作，但无济于事，因此我在这里请求有关如何调试的建议。

首先，运行Ubuntu 11.10

安装rvm：

$ bash < <(curl -s https://raw.github.com/wayneeseguin/rvm/master/binscripts/rvm-installer)

使用apt-get安装readline：

$ sudo apt-get install libreadline-dev

检查readline安装：

$ dpkg --get-selections | grep readline
lib64readline-gplv2-dev             install
lib64readline5                  install
libreadline-dev                 install
libreadline5                    install
libreadline6                    install
libreadline6-dev                install
readline-common                 install

安装ruby，有readline支持吗？

$ rvm install 1.9.2 --with-readline-dir=/usr

这是 rvm 版本：

$ rvm --version

rvm 1.9.2 by Wayne E. Seguin ([email protected]) [https://rvm.beginrescueend.com/]

让我们尝试 ruby​​ shell：

$ irb
1.9.2 :001 > puts "add history"
add history
 => nil 
1.9.2 :002 > ^[[A^[[A^[[A^[[A^[[A <------ PRESS UP ARROW DOES THIS

不，好吧，如果它不能与 ubuntu 的 readline 版本一起工作？？？让我们尝试使用 rvm 自己的 readline 版本：

$ rvm pkg install readline
Fetching readline-5.2.tar.gz to /home/keith/.rvm/archives
  % Total    % Received % Xferd  Average Speed   Time    Time     Time  Current

好的，那里有一个错误，让我们看一下：

正如预期的那样，irb 无法与 readline 一起使用：

PS - 是的，我已经“谷歌”这个问题了......

Answer 1

Ubuntu 12.04 这里：这里的答案有帮助，但也有误导性。

如果您使用的是 Ubuntu 12.04，请勿 pkg install readline，无论是否带有 --skip-autoreconf。完成此操作后，无论您为 rvm install 1.9.3 提供何种开关组合，readline 或 zlib 都将被破坏。

要使其正常工作，请执行rvm requests告诉您的apt-get install，执行pkg uninstall readline，然后执行简单的rvm remove 1.9 .3； rvm安装1.9.3

Answer 2

我在 Ubuntu 11.10 中也遇到了同样的问题。

就我而言，如果我使用以下内容，readline 似乎会正确编译：

$ rvm --skip-autoreconf pkg install readline

如 http://beginrescueend.com/packages/readline 底部所述/

但是，当我调用 irb 时，我会得到正常错误“Unable to require readline”

最后，基于 Shane 的命令行，我调用了以下命令：

$ rvm install 1.9.3 --with-readline-dir=$rvm_usr_path --with-iconv-dir=$rvm_usr_path --with-zlib-dir=$rvm_usr_path --with-openssl-dir=$rvm_usr_path

而不是 http://beginrescueend.com/packages/readline/

$ rvm install 1.9.2 --with-readline-dir=$rvm_path/usr

就我而言，版本 1.9.3 就是我想要的。 最终 irb 提出了一个有效的 readline。

感谢这里的每个人为我指明了正确的方向。

Answer 3

好吧，这看起来似乎很明显，但当你知道答案时总是如此：

我放弃使用 RVM，转而使用 rbenv - 我很高兴我这么做了！

sudo apt-get install libreadline-gplv2-dev
CONFIGURE_OPTS="--with-readline-dir=/usr/include/readline --with-openssl-dir=/usr/local" rbenv-install 1.9.2-p290

安装没有错误 - 我仍然不相信我需要 gplv2 软件包，因为我已经安装了 libreadline6-dev 。然而，这仍然没有解决我的问题。它确实从等式中删除了 RVM，并向我表明，尽管我尽了最大努力，IRB shell 仍拒绝使用 readline。

答案来自阅读这个伟大的指南：

RubyTools.pdf

在我的 ~/我发现 .irbrc 文件：

IRB.conf[:USE_READLINE] = false

快速更新：

IRB.conf[:USE_READLINE] = true

我正在用煤气做饭！

感谢您的所有精彩回答和建议，我非常感谢您的宝贵时间。

Answer 4

这解决了我使用 Ruby 1.9.3 的 rvm 问题

gem install rb-readline

Answer 5

我遇到了同样的问题，但我使用的是 11.04，并且阅读了您提供的链接 https://github .com/wayneeseguin/rvm/issues/553
从 peplins 评论中的信息中，我删除了此处添加的 autoreconf 调用
https://github.com/wayneeseguin/rvm/commit/94c301d
现在 readline 编译没有任何错误。在再次安装 ruby​​ 之前，我在编译 readline 后添加了 autoreconf 调用。

这就是我的工作方式：

编辑 ~/.rvm/scripts/functions/pkg 并删除以下内容：

if [[ "${rvm_skip_autoreconf_flag:-0}" == 0 ]] &&
  which autoreconf >/dev/null 2>&1 &&
  which libtoolize >/dev/null 2>&1 &&
  [[ -f configure.ac || -f configure.in ]]
then
__rvm_run "$package/autoreconf" \
  "autoreconf -is --force" \
  "Prepare $package in $rvm_src_path/$package-$version."
fi

编译 readline 并删除 ruby​​（我使用了 ree_dependency 命令，但我不确定这是必要的）：

rvm pkg install ree_dependencies
rvm remove 1.9.2

撤消删除到 ~/.rvm/scripts/functions/pkg
然后我用这个命令安装了 1.9.2（同样是来自 ree 安装，我不确定是否有必要，但这是我使用的）

rvm install 1.9.2 --with-readline-dir=$rvm_usr_path --with-iconv-dir=$rvm_usr_path --with-zlib-dir=$rvm_usr_path --with-openssl-dir=$rvm_usr_path

，现在一切似乎都正常工作，希望对某人有所帮助。

Answer 6

我的设置是 ubuntu 11.10、RVM 1.10.2、ruby 1.9.3。

此 readline 问题在运行 irb 时出现错误，并由于以下错误而阻止了 Rails 控制台的运行：

“require”：无法加载此类文件 -- readline (LoadError)

对我有用的解决方案是 Bryan Larsen 描述的解决方案，即

不要 pkg install readline，无论有或没有 --skip-autoreconf

执行 apt-get install rvm 要求告诉你做什么，然后

rvm --skip-autoreconf pkg 卸载读取行

rvm 删除 1.9.3

rvm安装1.9.3

感谢 Bryan 的提示。

Answer 7

这些步骤解决了我之前编译 ruby​​ 后的问题（在 Lubuntu 12.04 上），并且在每次运行时不断收到“编译 readline 丢失”错误：

sudo aptitude install build-essential openssl libreadline6 \
                      libreadline6-dev curl git-core zlib1g zlib1g-dev \
                      libssl-dev libyaml-dev libsqlite3-dev sqlite3 \
                      libxml2-dev libxslt-dev autoconf libc6-dev ncurses-dev \
                      automake libtool bison subversion
rvm pkg uninstall readline
rvm remove 1.9.3
rvm install 1.9.3

Answer 8

不幸的是，这些都不适合我。我最终使用了 http://beginrescueend.com/packages/readline/ 中的快速修复

解决了问题我的问题。

Answer 9

您可以尝试安装包libreadline5-dev的解决方法。
我猜 libreadline6-dev 现在无法工作。

Answer 10

对我来说，它只是在最新版本的 rvm 中开箱即用。 我的步骤：

bash -s stable < <(curl -s https://raw.github.com/wayneeseguin/rvm/master/binscripts/rvm-installer )

根据rvm要求

apt-get install build-essential openssl libreadline6 libreadline6-dev curl git-core zlib1g zlib1g-dev libssl-dev libyaml-dev libsqlite3-0 libsqlite3-dev sqlite3 libxml2-dev libxslt-dev autoconf libc6-dev ncurses-dev automake libtool bison subversion

rvm install 1.9.3

rvm

您可以看到它可以很好地工作我。

1 - 不要忘记安装 libedit-dev

# dpkg --get-selections| egrep '(readline|libedit)'
libedit-dev                                     install # <= BSD PACKAGE, not GNU, but... it is work fine to me
libedit2                                        install # the same story as previous
libreadline-dev                                 install
libreadline5                                    install
libreadline6                                    install
libreadline6-dev                                install
readline-common                                 install

2 - 卸载 pkg readline

$ rvm pkg uninstall readline

3 - 转到 $rvm_path/src/ruby-#{version}/ext/readline 并执行

$ ruby extconf.rb; make; make install

4 - 忘记头痛

Answer 12

如果您使用 Bundler 那么以下内容可能会有所帮助：

echo "gem 'rb-readline'" >> Gemfile
bundle install
