rbenv：bundle：在生产服务器上找不到命令

Posted 2023-01-13

我正在尝试部署rails应用程序，但它坚持错误

它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？

答案

您是否尝试首先在服务器上安装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

另一答案

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

另一答案

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

另一答案

更新： 我找到原因：我的.gemrc包含“gem：--user-install”，所以bundle不能安装在rbenv中，然后rbenv在2.1.2路径中找不到bundle二进制文件删除--user-install config ，并重新安装捆绑包resovle问题。

=================================== 我发现RBENV_VERSION env导致bundle失败，但不知道原因。我删除了RBENV_VERSION并在服务器上执行了cmd，它成功了。

另一答案

如果你查看你的.bashrc或.bash_profile，你会看到类似的东西：

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

要么：

[ -z "$PS1" ] && return

如果shell不是交互式的，这将阻止执行此行之后的所有内容。

Capistrano不会打开交互式shell。

例如，如果您使用rbenv，它会在.bashrc的末尾添加行。这些行未执行，因此未加载ruby环境。

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

在上面解释的返回之前，只需在.bashrc的开头移动rbenv行。
