无法安装gem -未能建立gem本地扩展-无法加载这样的文件——mkmf (LoadError)

Ruby 1.9.3

Gemfile的部分

#...............
gem "pony"
gem "bcrypt-ruby", :require => "bcrypt"
gem "nokogiri" 
#..................

当我试图安装宝石时，我得到一个错误

An error occurred while installing bcrypt-ruby (3.0.1), and Bundler cannot continue.
Make sure that `gem install bcrypt-ruby -v '3.0.1'` succeeds before bundling.

然后我做这个

sudo gem install bcrypt-ruby -v '3.0.1'

也会得到一个错误。

我错过了什么?

这对我很管用。捆绑包配置——全局构建。Snappy——with-opt-dir="$(brew -前缀Snappy)"

其他回答

还有类似的问题:

' require':没有这样的文件加载——mkmf (LoadError) 构建gem本地扩展失败(mkmf (LoadError)) - Ubuntu 12.04

通常，解决方案是:

sudo apt-get install ruby-dev

或者，如果这不起作用，根据你的ruby版本，运行如下代码:

sudo apt-get install ruby1.9.1-dev

应该能解决你的问题。

还是不行?安装ruby-dev后尝试以下操作:

sudo apt-get install make

在经历了几个小时的痛苦后，我终于找到了工作。

如果你正在运行brew..

brew install ruby

在终端输出/日志中，确定ruby安装的路径，brew建议“您可能想要将此添加到您的path”，所以这就是我们要做的。例如，我的是

/usr/local/lib/ruby/gems/3.0.0/bin

通过运行(省略大括号)将其添加到路径中

echo 'export PATH"{the_path_you_found_above}:$PATH"' >> ~/.bash_profile

然后通过运行更新环境

source ~/.bash_profile

现在，尝试运行您的安装，即，

sudo gem install middleman

在Mac中，这对我来说是有效的:

CONFIGURE_OPTS="--enable-shared" rbenv install 2.2.2

确保安装了ruby-dev 确保安装了Make 如果仍然得到错误，请查找建议的包。如果你想安装gem install pg，你还需要安装lib libpq-dev (sudo apt-get install libpq-dev)。

我正在做一个单词搜索应用程序，我必须安装cocoapods，在格式化我的mac并重新安装xcode后，当我想安装cocoapods时，我仍然得到了错误。

解决方法如下:

看起来CocoaPods 1.9.0(撰写本文时的最新版本)依赖于比2.3.7更新的Ruby版本。但是macOS Mojave只包含Ruby 2.3.7，所以你有几个不同的选择。

    Upgrade to macOS Catalina and get Ruby 2.6.3
    Use Ruby Version Manager to install a newer version of Ruby
    Install an older version of CocoaPods
    sudo gem install cocoapods -v 1.8.4

我做了3个:

Sudo gem安装cocoapods
