新手问题 Mac 构架 Ruby 环境,运行 Rails 时出错

chihwoo · 2018年06月05日 · 最后由 IChou 回复于 2018年06月17日 · 1132 次阅读

bundle时出错,出错信息是:

An error occurred while installing nokogiri (1.8.2), and Bundler cannot
continue.
Make sure that `gem install nokogiri -v '1.8.2' --source
'https://rubygems.org/'` succeeds before bundling.

求解。 Rails版本:Rails 4.2.6 Ruby版本:ruby 2.3.0p0 (2015-12-25 revision 53290) [x86_64-darwin15]

谢谢。

报错提示截取太少了 看不到原因 应该有生成一个 gem_make.out 的文件吧

打开看下里面爆了啥

看上去应该是你的环境缺少某个编译依赖

可能是找不到 libxml2 或者 libxslt

你看看 ls /usr/include/libxslt 有没有, 如果没有那就

brew install libxml2 libxslt
gem install nokogiri -v '1.8.2' -- --with-xslt-dir=/usr/local/opt/libxslt --with-xml2-dir=/usr/local/opt/libxml2

然后 bundle

我自己录制了 mac 下 rails开发环境的配置视频。你可以参考。https://itfun.tv/courses/25 直接QQ登录看,不需要注册了。

你直接 gem install nokogiri 会出现更详细的报错信息 然后报错信息里会指向一个页面 去那个页面里有解决方案~

可以看看官方文档,我比较喜欢用brew装libxml2,因为编译时间快。

brew install libxml2
# If installing directly
gem install nokogiri -- --use-system-libraries \
  --with-xml2-include=$(brew --prefix libxml2)/include/libxml2
# If using Bundle
bundle config build.nokogiri --use-system-libraries \
  --with-xml2-include=$(brew --prefix libxml2)/include/libxml2
bundle install

另外如果你用Rails 4.2的话,应该尽早升级到4.2.10和Ruby 2.3.7,否则会漏掉不少安全补丁。

chihwoo:~ goki$ brew install libxml2 libxslt
Error: libxml2 2.9.4 is already installed
To upgrade to 2.9.7, run `brew upgrade libxml2`
Error: libxslt 1.1.28_1 is already installed
To upgrade to 1.1.32, run `brew upgrade libxslt`

谢谢,貌似没有问题。

谢谢回复。 gem_make.out里的内容如下。 如何看哪里爆了呢?

这个报错,有点少见了,在编译阶段触发的,感觉像是 gcc 的问题呀 在你开始装环境之前 xcode-select --install 执行了么?

这个问题我也没遇到过,所以怎么处理也不是很确定

https://github.com/sparklemotion/nokogiri/issues/1111 这个里面稍微有提到一些

建议尝试:

xcode-select --install
rbenv uninstall 2.3.0
rbenv install 2.3.0
gem install nokogiri -v '1.8.2'

看看能不能解决

装个 node 就行了

chihwoo 回复

mac 别用 gcc, 把 gcc 卸掉

IChou 回复
Error: Your Xcode (7.3.1) is too outdated.
Please update to Xcode 9.4 (or delete it).
Xcode can be updated from the App Store.

好像提示我Xcode的版本低。。。我正在升级试试看。

luikore 回复

其实并不确定他是不是装了 gcc 🤪

jasl 回复

为什么装 node 可以解决这个呢?

IChou 回复

我确定啊, couldn't understand kern.osversion 就是 gcc 出来的:

https://github.com/gcc-mirror/gcc/blob/master/gcc/config/darwin-driver.c#L80

根本原因可能是看了太古老的教程

IChou 回复

看错了。。看成了 therubyracer

先执行 gem install nokogiri -v '1.8.2 看看这样的报错信息吧。

luikore 回复

请教有没有最新的安装教程呢? 人在海外。谢啦

chihwoo 回复

brew list 看看有没有 gcc 的包, 如果有就 brew remove 包名.

如果有 macports, 也用类似的方式删掉 gcc.

然后 gcc -v 看一下, 如果显示 Apple LLVM version ... (clang-...) 那就好了 (这是 LLVM 的假 gcc)

如果还有而且你不知道怎么删... 建议还是用 docker 搞吧 https://hub.docker.com/_/ruby/

《Rails 5 敏捷开发》/ 《Agile Web Development with Rails 5》

https://about.ac/books/agile-rails5/ 国内版本的介绍,论坛里也有不少介绍

或者

《Ruby on Rails 教程(原书第 4 版)》

请问是什么原因呢?

你没有当前目录的权限啊

应该怎么解决呢 T_T

cd 到一个你有权限的目录去执行,或者修改当前目录的权限
