我正在尝试部署rails应用程序，但它仍然存在错误

它正在使用正确的红宝石版本。但我想尝试在另一个文件夹中安装宝石。我该如何修复它？

Answer 1

您是否曾尝试在服务器上安装gem“bundler”？运行bundle命令需要此gem。 SSH到您的服务器并运行以下命令：

gem install bundler

希望有所帮助

Answer 2

如果你已经安装了bundler（bundler -v）试一试（它在Ubuntu 12.04 LTS上适用于我）：

1. gem uninstall bundler
2. gem update
3. gem install bundler
4. redeploy

Answer 3

它对我有用。我正在使用Ubuntu 16.04.Change用户下面的用户名。

sudo pico /etc/profile.d/rbenv.sh

#File
export RBENV_ROOT=/home/user/.rbenv
export PATH=$RBENV_ROOT/shims:$RBENV_ROOT/bin:$PATH
#End File

Answer 4

更新：
我找到原因：我的.gemrc包含＆＃34; gem： - user-install＆＃34;，所以捆绑不能安装在rbenv中，然后rbenv无法在2.1.2路径中找到捆绑二进制文件删除--user-install配置，然后重新安装bundle以解决问题。

===================================
我发现RBENV_VERSION env导致捆绑失败，但不知道为什么。我删除了RBENV_VERSION并在服务器上执行了cmd，它成功了。

Answer 5

如果查看您的.bashrc或.bash_profile，您将看到类似的内容：

case $- in
    *i*) ;;
      *) return;;
esac

或者：

[ -z "$PS1" ] && return

如果外壳不是交互式的，这将阻止执行此行之后的所有内容。

Capistrano无法打开交互式外壳。

例如，如果您使用的是rbenv ，它将在.bashrc的末尾添加行。这些行未执行，因此未加载您的ruby环境。

export PATH="$HOME/.rbenv/bin:$PATH"
eval "$(rbenv init -)"
export PATH="$HOME/.rbenv/plugins/ruby-build/bin:$PATH"

只需将rbenv行移到您的.bashrc开头，再返回上述返回值即可。

rbenv：bundle：在生产服务器上找不到命令
