使用 rbenv 进行 capistrano 部署：/home/deploy/.rbenv/bin/rbenv：没有这样的文件或目录

Question

我最近在我的 ubuntu 服务器上从 rvm 切换到 rbenv。 我已按照官方文档https://github.com/rbenv/rbenv中的所有说明进行操作。 当我尝试使用 capistrano 进行部署时，我遇到了一条错误消息，提示它找不到 /bin/rbenv 目录。

 00:24 bundler:config 01 RBENV_ROOT=$HOME/.rbenv RBENV_VERSION=2.5.8 $HOME/.rbenv/bin/rbenv exec bundle config --local deployment true 01 bash: /home/deploy/.rbenv/bin/rbenv: No such file or directory #<Thread:0x00007ff4640d25e0@/Users/kevinsun/.rvm/gems/ruby-2.5.8@wager/gems/sshkit-1.21.2/lib/sshkit/runners/parallel.rb:10 run> terminated with exception (report_on_exception is true): Traceback (most recent call last): 1: from /Users/kevinsun/.rvm/gems/ruby-2.5.8@wager/gems/sshkit-1.21.2/lib/sshkit/runners/parallel.rb:11:in `block (2 levels) in execute' /Users/kevinsun/.rvm/gems/ruby-2.5.8@wager/gems/sshkit-1.21.2/lib/sshkit/runners/parallel.rb:15:in `rescue in block (2 levels) in execute': Exception while executing as deploy@3.133.135.38: bundle exit status: 127 (SSHKit::Runner::ExecuteError) bundle stdout: Nothing written bundle stderr: bash: /home/deploy/.rbenv/bin/rbenv: No such file or directory (Backtrace restricted to imported tasks) cap aborted: SSHKit::Runner::ExecuteError.

Exception while executing as deploy@3.133.135:38: bundle exit status: 127 bundle stdout: Nothing written bundle stderr: bash. /home/deploy/:rbenv/bin/rbenv: No such file or directory

在我的实例中，深入该目录，我可以确认 /home/deploy/.rbenv/ 下没有 /bin/rbenv

 ubuntu@ip-10-0-0-163:/home/deploy/.rbenv$ ls -a. .. plugins shims versions

我试过根据这个答案摆弄我的部署文件，但无济于事。

这是我的 Gemfile、Capfile 和 deploy.rb：

这对我有帮助，我遇到了同样的问题，capistrano 无法找到 rbenv 二进制文件

set :rbenv_prefix, '/usr/bin/rbenv exec'

感谢 github 上的这个问题，其中指出github
