标签: rbenv

Ruby最近停止了我兄弟的机器.

• gem 命令
• rails server
• rails console

全部失败,出现以下错误:

$ irb
irb(main):001:0> require 'digest/sha1'

LoadError: dlopen(~/.rbenv/versions/2.0.0-p0/lib/ruby/2.0.0/x86_64-darwin12.2.0/digest/sha1.bundle, 9): Symbol not found: _rb_Digest_SHA1_Finish

    from ~/.rbenv/versions/2.0.0-p0/bin/irb:12:in `<main>'

他尝试了不同版本的Ruby.重新安装一切rvm.运行rvm implode并重新安装rvm.切换到rbenv.通过安装几个红宝石ruby-build.brew install ruby.

所有人都有同样的问题.

如果他卸载了所有红宝石,操作系统提供的版本/usr/bin/ruby就可以了.但它是1.8.7.

经过数小时的故障排除后,我们得出了以下解决方案.我希望它可以帮助你避免一些痛苦.

我对rbenv很新,更不用说ruby并且在诊断以下安装失败时遇到一些困难:

我正在尝试使用 Dockerfile 设置 rbenv，但这在rbenv install. 我确实在那里有 ruby​​-build，它似乎不起作用。

Dockerfile 的相关部分（主要来自https://gist.github.com/deepak/5925003）：

# 安装 rbenv
运行 git clone https://github.com/sstephenson/rbenv.git /usr/local/rbenv
运行 echo '#rbenv setup' > /etc/profile.d/rbenv.sh
运行 echo 'export RBENV_ROOT=/usr/local/rbenv' >> /etc/profile.d/rbenv.sh
运行 echo 'export PATH="$RBENV_ROOT/bin:$PATH"' >> /etc/profile.d/rbenv.sh
运行 echo 'eval "$(rbenv init -)"' >> /etc/profile.d/rbenv.sh
运行 chmod +x /etc/profile.d/rbenv.sh

# 安装 ruby​​-build
运行 mkdir /usr/local/rbenv/plugins
运行 git clone https://github.com/sstephenson/ruby-build.git /usr/local/rbenv/plugins/ruby-build

ENV 路径 /usr/local/rbenv/shims:/usr/local/rbenv/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin

# 设置为 Ruby 2.0.0-p247
运行 rbenv 安装 2.0.0-p247
运行 rbenv 重新哈希
运行 rbenv 本地 2.0.0-p247 …

任何使用的命令sudo似乎都不适用于RBenv.

我正在尝试安装ActiveRecord,它说我没有写权限,所以当我尝试这个时:

ERROR:  While executing gem ... (Gem::FilePermissionError)
    You don't have write permissions into the /usr/local/rbenv/versions/1.9.3-p194/lib/ruby/gems/1.9.1 directory.

它说:

sudo: gem: command not found

我怎么能绕过这个？

我尝试更新我的 ruby​​ 和 Rails 版本。但我最终遇到了这个错误：

~ ruby -v
/Users/Benjamin/.rbenv/shims/ruby: line 21: /usr/local/Cellar/rbenv/1.1.0/libexec/rbenv:
No such file or directory

我能做些什么来解决这个问题吗？

当我尝试启动 Rails 服务器时，出现以下错误：

$ bundle exec rails s
Your Ruby version is 2.3.7, but your Gemfile specified ~> 2.3.8

我不明白为什么会发生这种情况，因为我使用 Homebrew 和 rbenv 将 Ruby 设置为 2.3.8。2.3.7是系统的ruby版本。我使用的是 Mac 操作系统 10.14.4。

$ ruby -v
ruby 2.3.8p459 (2018-10-18 revision 65136) [x86_64-darwin18]

$ rbenv version
2.3.8 (set by /Users/ceasar/foo/.ruby-version)

$ which -a ruby
/Users/ceasar/.rbenv/shims/ruby
/usr/local/opt/ruby@2.3/bin/ruby
/usr/local/bin/ruby
/usr/bin/ruby

$ which -a bundle
/Users/ceasar/.rbenv/shims/bundle
/usr/local/bin/bundle

$ /usr/bin/xcodebuild -version
Xcode 10.2
Build version 10E125

$ brew list ruby@2.3
/usr/local/Cellar/ruby@2.3/2.3.8_1/bin/erb
/usr/local/Cellar/ruby@2.3/2.3.8_1/bin/gem
/usr/local/Cellar/ruby@2.3/2.3.8_1/bin/irb
/usr/local/Cellar/ruby@2.3/2.3.8_1/bin/rake
/usr/local/Cellar/ruby@2.3/2.3.8_1/bin/rdoc

/usr/local/Cellar/ruby@2.3/2.3.8_1/bin/ruby
/usr/local/Cellar/ruby@2.3/2.3.8_1/include/ruby-2.3.0/ …

所以我在 Mac OS Mojave 上将我的 Ruby 升级到 2.4.9。

我在安装 gem 时遇到问题...

    proj$ gem install google-cloud-vision
ERROR:  Loading command: install (LoadError)

proj$ ruby -v

我已经做了一堆 brew update && brew upgrade ，但我被卡住了......有什么指示吗？

我正在尝试在我的 Mac（带有所有更新的最新操作系统）上安装 Ruby 版本 2.7.2 并执行以下操作

brew update
brew upgrade rbenv ruby-build

进而

rbenv install 2.7.2
ruby-build: definition not found: 2.7.2

See all available versions with `rbenv install --list'.

If the version you need is missing, try upgrading ruby-build:

  brew update && brew upgrade ruby-build

所以我尝试按照上面的说明进行操作并得到这个

brew update && brew upgrade ruby-build
Already up-to-date.
Warning: ruby-build 20200926 already installed

我正在尝试使用rbenv在远程服务器上安装Ruby。
