Git 在 Powershell 说“找不到 ssh-agent”

我已经安装了 git，它在命令提示符下工作得很好，但是当我打开 powershell 时，它会给我这样的警告:

WARNING: Could not find ssh-agent

我有选美比赛，还有私人钥匙。这在所有的 gui 工具和命令提示符中都适用，但在 Powershell 不适用。

发生什么事了？

I figured it out. You need to set GIT_SSH environment variable on your machine to point to plink.exe. This could be the one installed with TortoiseHg / TortoiseGit / Git Extensions or you can download it from Putty Download Page, but just make sure that you use the same one system wide. Best to log out from your Windows session to make sure this variable gets set for all Explorer instances and command windows.

For those looking for a detailed explanation have a read of this blog post. Below is a quote from the blog post. Ultimately the ssh-agent.exe needs to be in the path, or resolved some other way.

EDIT: It appears most of the people don't bother reading the linked blog and the original extract did not quote the full solution, so I've expanded the quote from the blog below.

There are numerous ways to resolve the error, based on the likes to all other answers. One known to work is quoted below. Scan though other answers they may be more appropriate for you.

When I restarted my PowerShell prompt, it told me it could not start SSH Agent.

It turns out that it was not able to find the “ssh-agent.exe” executable. That file is located in C:\Program Files (x86)\Git\bin. but that folder isn’t automatically added to your PATH by msysgit.

If you don’t want to add this path to your system PATH, you can update your PowerShell profile script so it only applies to your PowerShell session. Here’s the change I made.

$env:path += ";" + (Get-Item "Env:ProgramFiles(x86)").Value + "\Git\bin"

On my machine that script is at: C:\Users\Haacked\Documents\WindowsPowerShell\Microsoft.Powershell_profile.ps1

If you are using posh-git and getting this warning, you can turn it off by commenting (adding a '#' sign to) the following line 

Start-SshAgent -Quiet

In the file

Documents\WindowsPowerShell\Modules\posh-git\profile.example.ps1

You can add two lines to the top of your profile (type ise $profile) to fix this PoshGit issue without polluting your Path. Then run . $profile to reload your profile.

For 32-bit git

Set-Alias ssh-agent "${env:ProgramFiles(x86)}\git\bin\ssh-agent.exe"
Set-Alias ssh-add "${env:ProgramFiles(x86)}\git\bin\ssh-add.exe"

For 64-bit git

Set-Alias ssh-agent "$env:ProgramFiles\git\usr\bin\ssh-agent.exe"
Set-Alias ssh-add "$env:ProgramFiles\git\usr\bin\ssh-add.exe"

To run ssh-agent with specified key I wrote this code:

$gitexepath = cmd /c where git
$gitbindir = Join-Path $gitexepath "..\..\bin"
$sshagentpath = Join-Path $gitbindir "ssh-agent.exe"
$sshaddpath = Join-Path $gitbindir "ssh-add.exe"
$keypath = "...key path...":
$sshagentres = cmd /c $sshagentpath
$env:SSH_AUTH_SOCK = [System.Text.RegularExpressions.Regex]::Match($sshagentres, "(?<=SSH_AUTH_SOCK=).+?(?=;)").Value
$env:SSH_AGENT_PID = [System.Text.RegularExpressions.Regex]::Match($sshagentres, "(?<=SSH_AGENT_PID=).+?(?=;)").Value
cmd /c $sshaddpath $keypath

This has been fixed; see https://github.com/dahlbyk/posh-git/issues/160

You can update posh-git.
