您对/var/lib/gems/2.3.0目录没有写入权限 [英] You don't have write permissions for the /var/lib/gems/2.3.0 directory

问题描述

  $ which ruby​​ 
 
 / usr / bin / ruby​​ 
 
 $ ruby​​ -v 
 
 ruby​​ 2.3.0p0（2015-12-25）[x86_64-linux-gnu] 
 
 $ gem install bundler 
 
错误：执行gem时（Gem :: FilePermissionError）
您没有写入/var/lib/gems/2.3.0目录的权限。 
  

任何帮助都将不胜感激！

解决方案

首先需要用类似于的方式卸载由Ubuntu安装的ruby，sudo apt-get remove ruby​​ 。

然后使用 rbenv 和 ruby​​-build 根据他们的文档：

 < coded> cd $ HOME $ b $ sudo apt-get update $ b $ sudo apt-get install git-core curl zlib1g-dev build-essential libssl-dev libreadline-dev libyaml-dev libsqlite3-dev sqlite3 libxml2 -dev libxslt1-dev libcurl4-openssl-dev python-software-properties libffi-dev 
 
 git clone https://github.com/rbenv/rbenv.git〜/ .rbenv 
 echo 'export PATH =$ HOME / .rbenv / bin：$ PATH'>> 〜/ .bashrc 
 echo'eval$（rbenv init  - ）'>> 〜/ .bashrc 
 exec $ SHELL 
 
 git clone https://github.com/rbenv/ruby-build.git〜/ .rbenv / plugins / ruby​​-build 
 echo'export PATH =$ HOME / .rbenv / plugins / ruby​​-build / bin：$ PATH'>> 〜/ .bashrc 
 exec $ SHELL 
 
 rbenv install 2.3.1 
 rbenv global 2.3.1 
 ruby​​ -v 
  
 
 
 
最后一步是安装Bundler： > gem install bundler 
 rbenv rehash 
  

然后享受！

I have ruby installed on my ubuntu 16.04.

$which ruby  

/usr/bin/ruby

$ruby -v 

ruby 2.3.0p0 (2015-12-25) [x86_64-linux-gnu]

$gem install bundler 

ERROR:  While executing gem ... (Gem::FilePermissionError)
    You don't have write permissions for the /var/lib/gems/2.3.0 directory.

Any help will be greatly appreciated!

解决方案

You first need to uninstall the ruby installed by Ubuntu with something like sudo apt-get remove ruby.

Then reinstall ruby using rbenv and ruby-build according to their docs:

cd $HOME
sudo apt-get update 
sudo apt-get install git-core curl zlib1g-dev build-essential libssl-dev libreadline-dev libyaml-dev libsqlite3-dev sqlite3 libxml2-dev libxslt1-dev libcurl4-openssl-dev python-software-properties libffi-dev

git clone https://github.com/rbenv/rbenv.git ~/.rbenv
echo 'export PATH="$HOME/.rbenv/bin:$PATH"' >> ~/.bashrc
echo 'eval "$(rbenv init -)"' >> ~/.bashrc
exec $SHELL

git clone https://github.com/rbenv/ruby-build.git ~/.rbenv/plugins/ruby-build
echo 'export PATH="$HOME/.rbenv/plugins/ruby-build/bin:$PATH"' >> ~/.bashrc
exec $SHELL

rbenv install 2.3.1
rbenv global 2.3.1
ruby -v

The last step is to install Bundler:

gem install bundler
rbenv rehash

Then enjoy!
