总而言之，我正在尝试使用LetsEncrypt向自己颁发SSL证书，并且最近安装了rbenv来简化此过程.安装rbenv后，我检查是否使用
Long story made short, I am trying to issue myself an SSL certificate using LetsEncrypt, and have recently installed rbenv to make this process easier. After installing rbenv, I check to see if everything checks out using
curl -fsSL github/rbenv/rbenv-installer/raw/master/bin/rbenv-doctor | bash我比得到此消息说没有安装任何版本的ruby.尝试使用命令
I than get this message saying that there are no versions of ruby installed. After trying to install ruby using the command
"rbenv install 2.3.1"
我收到此错误
rbenv: no such command `install'是因为我的rbenv垫片的路径不在我的PATH变量中吗?如果是这种情况，如何将目录添加到PATH变量中?我知道您必须将它们添加到bash_profile文件中，但是不确定在该文件中我需要添加什么内容以及需要添加什么内容.
Is it because the path to my rbenv shims aren't in my PATH variable ? If this is the case how do I add directories to my PATH variable ? I know you have to add them to your bash_profile file, but am not sure where in this file I need to add something, and what I need to add.
〜/.bash_profile
~/.bash_profile
# .bash_profile # Get the aliases and functions if [ -f ~/.bashrc ]; then . ~/.bashrc fi # User specific environment and startup programs function letsencrypt_webfaction { PATH=$PATH:$GEM_HOME/bin GEM_HOME=$HOME/.letsencrypt_webfaction/gems RUBYLIB=$GEM_HOME/lib ruby2.2 $HOME/.letsencrypt_webfaction/gems/bin/letsencrypt_webfaction $* } eval "$(rbenv init -)" PATH=$PATH:$HOME/bin export PATH export PATH="$HOME/.rbenv/bin:$PATH"推荐答案
在编辑配置文件时始终要小心.
Always be careful when editing the profile.
最好先备份
- 切换到主目录: cd
- 列出隐藏文件: ls -la .bash*
- 制作.bash_profile的备份副本: cp -p .bash_profile .bash_profile.bak
- 检查当前路径:echo $PATH
- 检查ruby是否在PATH中:which ruby
- 检查红宝石版本:ruby --version
- switch to home directory: cd
- list hiden files: ls -la .bash*
- make a backup copy of .bash_profile: cp -p .bash_profile .bash_profile.bak
- check the current PATH: echo $PATH
- check if ruby is in the PATH: which ruby
- check the ruby version: ruby --version
我不确定您的.bash_profile中该功能的来源:function letsencrypt_webfaction()
I am not sure where this function is comming from in your .bash_profile: function letsencrypt_webfaction()
使用:作为分隔符，并在PATH中添加新目录new_dir，使用$PATH保留实际PATH的内容，然后导出新PATH:
Use : as a separator and add a new directory new_dir to your PATH, use $PATH to keep the contents of the actual PATH, then export the new PATH:
PATH=$PATH:/new_dir:/new_lib export PATH验证终端是否需要该PATH:echo $PATH
Verify if the PATH is what you need from the terminal: echo $PATH
我个人认为应该直接备份.bash_profile.用#注释该函数的3行以及PATH出现的其他行，并添加以下内容:
Personaly I sugest making a backup of .bash_profile as it is. Comment out with # the 3 lines for the function and the others where the PATH appears and add this:
export RUBYLIB=$HOME/lib export GEM_HOME=$HOME/gems export PATH=$HOME/bin:$PATH:在此之后，请检查上方的小圆点，看看您是否拥有所需的红宝石版本.
After this please check the bulet points above and see if you have the ruby version you expect.
