macos 在 tmux 模式下丢失 vim 颜色方案

lose vim colorscheme in tmux mode

提问by tristen

I'm running iterm2 and when I'm in tmux mode the colorscheme I have set in vim does not show up. Only the color scheme I've set in iterm. If I run vim from shell the colorscheme appears correct - its only when I'm in tmux mode.

我正在运行 iterm2，当我处于 tmux 模式时，我在 vim 中设置的颜色方案没有显示出来。只有我在 iterm 中设置的配色方案。如果我从 shell 运行 vim，颜色方案看起来是正确的 - 只有当我处于 tmux 模式时。

I've tried setting :colorscheme molokaiwhen in vim (see screenshot below) and it doesn't change - again, the default colorscheme for iterm2 remains.

我试过:colorscheme molokai在 vim 中进行设置（见下面的截图）并且它没有改变 - 同样，iterm2 的默认颜色方案仍然存在。

Am I missing some setting to iterm or tmux.conf? My dotfles are up on github here.

我是否缺少 iterm 或 tmux.conf 的一些设置？我的 dotfles 在 github 上。

I had the same problem. Only difference was I am using solarizerather then molokai.

我有同样的问题。唯一的区别是我使用的是solarize而不是molokai.

To fix the issue, I have set up an alias in ~/.bashrc:

为了解决这个问题，我在以下位置设置了一个别名~/.bashrc：

alias tmux="TERM=screen-256color-bce tmux"

And set up the default-terminaloption in ~/.tmux.conf:

并default-terminal在~/.tmux.conf以下位置设置选项：

set -g default-terminal "xterm"

Lastly, do $ source ~/.bashrcto load new alias.

最后，$ source ~/.bashrc加载新别名。

As @romainl mentions above, I needed to force tmux to use 256 colors by adding the -2flag:

正如@romainl 上面提到的，我需要通过添加-2标志来强制 tmux 使用 256 种颜色：

$ tmux -2

I added alias tmux='tmux -2'to my bash_profile, so, I don't forget :)

我添加alias tmux='tmux -2'到我的 bash_profile，所以，我不会忘记 :)

I tried all the solutions above and what finally worked for me is putting the following lines in .tmux.conf:

我尝试了上述所有解决方案，最终对我有用的是将以下几行放入.tmux.conf：

set -g default-terminal "xterm-256color"

I just discovered why I was having a lot of confusion. I, like others here, was having a difficult time getting the default-terminal setting to take effect. I remembered that I had a tmux session in the background. I re-attached my session, closed out my processes, and closed ALL tmux processes. The next time I restarted tmux the default-terminal setting in .tmux.confbegan to take effect. I don't know if others are doing this as well but I recommend closing all tmux processes before modifying the .tmux.conffile.

我刚刚发现为什么我有很多困惑。我和这里的其他人一样，很难让默认终端设置生效。我记得我在后台有一个 tmux 会话。我重新附加了我的会话，关闭了我的进程，并关闭了所有 tmux 进程。下次我重新启动 tmux 时，默认终端设置.tmux.conf开始生效。我不知道其他人是否也这样做，但我建议在修改.tmux.conf文件之前关闭所有 tmux 进程。

I got my setup to work on my local machine (OSX 10.9.5 with iTerm2) without any modification to .bashrcor .bash_profile. All I did was add the line set -g default-terminal "xterm-256color"to ~/.tmux.confand restarted all tmux processes.

我让我的设置在我的本地机器上工作（带有 iTerm2 的 OSX 10.9.5），而没有对.bashrc或进行任何修改.bash_profile。我所做的只是将行添加set -g default-terminal "xterm-256color"到~/.tmux.conf并重新启动所有TMUX过程。

I got my remote setup (ssh to Ubuntu 14.04) to work exactly the same way without any modifications to .bashrc. I simply added set -g default-terminal "xterm-256color"to ~/.tmux.confon my remote machine and restarted all remote tmux processes.

我让我的远程设置（ssh 到 Ubuntu 14.04）以完全相同的方式工作，无需对.bashrc. 我只是在我的远程机器上添加set -g default-terminal "xterm-256color"到~/.tmux.conf并重新启动所有远程 tmux 进程。

You can test what Vim is seeing by doing echo $TERMfrom within a tmux session. It kept saying screenas the value until I restarted all tmux processes, at which point it reflected xterm-256coloras expected.

您可以通过echo $TERM在 tmux 会话中执行操作来测试 Vim 看到的内容。它一直说screen这个值，直到我重新启动所有 tmux 进程，此时它xterm-256color按预期反映。

Hope that helps.

希望有帮助。

So this a bit on the stale side, but it's might be worth mentioning that using screen will often break the Home and End keys. Using

所以这有点陈旧，但值得一提的是，使用 screen 通常会破坏 Home 和 End 键。使用

export TERM="xterm-256color"

in should keep the functionality of these and allow the color scheme (or powerline) to work fine.

in 应该保持这些功能并允许配色方案（或电力线）正常工作。

I needed vim to display correctly with tmux in terminal on ubuntu and cygwin/mintty on windows. I got it to work by combining the answers like this.

我需要 vim 在 ubuntu 上的终端和 cygwin/mintty 在 windows 上使用 tmux 正确显示。我通过结合这样的答案让它工作。

In .bashrc:

在 .bashrc 中：

alias tmux="tmux -2"

In .vimrc:

在 .vimrc 中：

" use 256 colors in terminal
if !has("gui_running")
    set t_Co=256
    set term=screen-256color
endif

" fix cursor display in cygwin
if has("win32unix")
    let &t_ti.="\e[1 q"
    let &t_SI.="\e[5 q"
    let &t_EI.="\e[1 q"
    let &t_te.="\e[0 q"
endif

I have tried all of the instructions above, and I found out the most important thing is I have to explicitly add the following line in my .bashrc file.

我已经尝试了上面的所有说明，我发现最重要的是我必须在我的 .bashrc 文件中明确添加以下行。

export TERM=screen-256color

I don't know why alias tmux="TERM=screen-256color-bce tmux" doesn't work out. I use Sierra 10.12.1.

我不知道为什么 alias tmux="TERM=screen-256color-bce tmux" 不起作用。我使用 Sierra 10.12.1。

In case anyone needs 24-bit color support:

如果有人需要 24 位颜色支持：

Tmux supports 24-bit color as of version 2.2. If your terminal supports 24-bit color, add your terminal to the terminal-overrides setting. For example,

从版本 2.2 开始，Tmux 支持 24 位颜色。如果您的终端支持 24 位颜色，请将您的终端添加到终端覆盖设置中。例如，

set -ga terminal-overrides ",xterm-256color:Tc"

My environment checklist:

我的环境清单：

• macOS Sierra 10.12.3
• iTerm2 3.0.14 (Report Terminal Type is xterm-256color)
• neovim 0.1.7 (Enable 24-bit color by adding: xterm-256colorto .vimrc)
• tmux 2.3 (Add set -ga terminal-overrides ",xterm-256color:Tc"to .tmux.conf)

Nothing else I need to add in .bashrcor .zshrc.

Hope this could help.

Adding the following line in .tmux.conf worked for me with macOS Sierra 10.12.6,

在 .tmux.conf 中添加以下行适用于 macOS Sierra 10.12.6，

set -g default-terminal "screen-256color"

set -g 默认终端“screen-256color”
