$ brew doctor
Warning: You have uncommitted modifications to Homebrew
If this a surprise to you, then you should stash these modifications.
Stashing returns Homebrew to a pristine state but can be
undone should you later need to do so for some reason.

尝试安装XCode,这往往是一个巨大的下载:
$ xcode-select --install
如果结果如下所示,那就可以了。
command line tools are already installed,
use "Software Update" to install update
更新OSX以确保其正常且最新:
Apple Menu -> About This Mac -> Software Update
在撰写本文时,确认您有一个当前系统,10.10:
$ sw_vers
ProductName: Mac OS X
ProductVersion: 10.10
BuildVersion: 14A389
如果您使用自制软件包管理器,那么什么版本? (请发布输出)
$ brew --version
验证brew是否健康:
$ brew doctor
如果医生发现任何错误,请修复这些错误。例如,医生可能会说这样做,所以这样做:
cd /usr/local/Library && git stash && git clean -d -f –
当医生说一切都很好的时候,然后带上冲泡电流:
$ brew update
$ brew upgrade
自制软件添加GCC吗? (请发布输出)
$ brew info gcc
GCC是否可用?
$ command -v gcc
/usr/bin/gcc
查看您的CC
编译器变量是空白还是已设置。 (请发布输出)
$ echo $CC
你在运行什么GCC版本? (请发布输出)
$ gcc -v

你在Ruby看的地方安装了GCC吗? (请发布输出)

如果您是root用户,是否会安装gem?
$ sudo su -
$ gem install bcrypt
答案 1 :(得分:0)
这里的根本问题是ruby本身带有bcrypt版本3.1.5,它有更新的更新错误。然而,当你安装或卸载bcrypt时,你会在bcrypt-ruby之后留下它总是要求的,所以你所做的一切都不会经过这样做怎么办? 1-通过运行以下两个命令卸载bcrypt和bcrypt-ruby:
$ gem uninstall bcrypt
和
$ gem uninstall bcrypt-ruby
2-用
重新安装gem install bcrypt --platform=ruby
在你的Gemfile中写上gem'bcrypt','〜&gt; 3.1.11'
现在,当我写这些行时,最新版本是3.1.11,但无论更新版本,只需从他们的宝石页面添加它。运行bundle install,它应该可以正常工作。
我希望您完全理解它的解决方案和机制,因此您会知道捆绑安装可能会导致同样的问题,因此您必须重复此过程并且它将再次起作用。

坚持一个旧项目,我可以通过以下步骤安装宝石(检查你自己的路径 - 不要只是复制粘贴):
1)安装所需的特定gcc版本(查看版本):
<table class="table table-bordered table-condensed">
<tr>
<th>Days</th>
<th>Date</th>
<th>Calories</th>
<th>Happiness</th>
<th>Hunger</th>
<th>Motivation</th>
</tr>
<tr>
<td>1</td>
<td id="day">{{dayArray[0]}}</td>
<td id="calorie">{{calorieArray[0]}}</td>
<td><input placeholder="0" /></td>
<td><input placeholder="0" /></td>
<td><input placeholder="0" /></td>
</tr>
<tr>
<td>2</td>
<td id="day">{{dayArray[1]}}</td>
<td id="calorie">{{calorieArray[1]}}</td>
<td><input placeholder="0" /></td>
<td><input placeholder="0" /></td>
<td><input placeholder="0" /></td>
</tr>
<tr>
<td>3</td>
<td id="day">{{dayArray[2]}}</td>
<td id="calorie">{{calorieArray[2]}}</td>
<td><input placeholder="0" /></td>
<td><input placeholder="0" /></td>
<td><input placeholder="0" /></td>
</tr>
<tr>
2)符号链接已安装的gcc目录:
brew install gcc46
3)安装报告错误的gem(检查你的宝石名称)
ln -s /usr/local/Cellar/gcc\@4.6/4.6.4_2 /usr/local/Cellar/gcc46/4.6.4
