Windows 无法识别 Docker 命令

Question

I already installed Docker for windows. when I type docker --version command in Command prompt, it doesn't recognize it at all.

The message will be this:

'docker' is not recognized as an internal or external command,
operable program or batch file.

Did I miss something?

Answer 1

I had installed Docker 18.06.1-ce version on my Windows 10 machine and faced the similar issue, even though the docker was added the Windows %PATH%.

I moved the docker path to the bottom and that solved my problem.

Answer 2

我重新启动了系统，它工作，也许我们可以说需要重新启动。

Answer 3

You need to start the docker first if you have not and then open powershell .

In the powershell, try to run docker commands.

Answer 4

I installed docker Docker version 19.03.13 build 4484c46d9d, in Windows 10 pro 1903. I was facing the same issue, then I just renamed 'com.docker.cli' to 'docker' and set the environment variable to 'C:\Program Files\Docker\Docker\resources\bin'

Problem Resolved.

Answer 5

将“com.docker.cli”重命名为“docker”帮助我最终让 windows powershell 和 cmd 终端识别 docker 命令。

Answer 6

Add docker to PATH variable & refreshenv to keep using the same command prompt

---

If you've installed using docker toolbox the install path "C:\Program Files\Docker Toolbox"

Manually using Environmental Variable > Path (add docker path here)

---

Using Command Line

For temporary use set PATH=%PATH%;C:\Program Files\Docker Toolbox

• Make sure to take a back up of PATH by echo %PATH% before doing this

For permanent change setx PATH=%PATH%;C:\Program Files\Docker Toolbox

Answer 7

docker: command not found

Windows 7: Just set the path of docker in

[Click on path -> edit-> paste the docker location]

[Paste the docker location] .

now check

Answer 8

Make sure the docker.exe path (C:\Program Files\Docker\Docker\resources\bin) is added to the PATH variable.

You can check it as follows:

ECHO %PATH%

The docker path had to be appended at the end of the PATH in my case. After that docker cmd was recognized.

Answer 9

Run as administrator worked for me, both powershell and bash on windows. I did not need to restart.

Answer 10

Just Restart the system, it is always good practice to restart the system when you install or uninstall any application. Hope this works :)

Answer 11

You need to restart the system after installation. It worked for me.

Answer 12

I checked environment variables and noticed that docker path is as the following path in which "R" in resources uppercase. I fixed the case and everything worked as expected Path: "C:\Program Files\Docker\Docker\Resources\bin"

Answer 13

Try to install GIT bash and then run this command on it for Windows:

base=https://github.com/docker/machine/releases/download/v0.16.0 &&
mkdir -p "$HOME/bin" &&
curl -L $base/docker-machine-Windows-x86_64.exe > "$HOME/bin/docker-machine.exe" &&
chmod +x "$HOME/bin/docker-machine.exe"

Click Here.

there is some issues with PowerShell or new version of docker due to which I was facing the same issue but then I went to this page and got way to run it.

PS: GIT bash is required.

Answer 14

如果您在 Windows 中安装了 Docker Toolbox，请添加环境变量。

PATH = "location of folder that contains docker-machine"

Answer 15

I also face a problem with the installation and running docker. I'm not sure you how did you install docker. I tried this way. I've downloaded the docker toolbox ( https://github.com/docker/toolbox/releases ) which comes up with docker,docker-machine. Oracle Virtual box which is pretty much enough to start docker locally.Please make sure you have git bash installed in your local. Once the toolbox installation is done click the icon generated on the desktop . Make sure this icon target to your Git bash.exe (you can verify this by right click on icon and find target). and verify docker version

Answer 16

For me, I had to ensure the check box Enable Hyper-V Windows Features is checked as I was installing.

I just wanted to have client installed, without the engine. So earlier, as I was installing, I unchecked that option. And after successful installation, I get the error - windows does not recognize docker.

But now that reinstalled with the checkbox checked, things are working fine now.

Answer 17

I noticed that running docker commands before startup causes this issue, but ensuring that docker is running and executing the commands after, they are then recognised.

Answer 18

For those who are facing docker issue on VS Code

I was trying on VS Code Terminal after installation. Restarted and was still facing issue.

Then I tried with fresh terminal of Command Prompt -- it worked!

After that it also working fine on vs code.

In VS Code - close all terminals and open fresh terminal and try test command:

docker --version

Answer 19

I've tried to play with paths but it didn't work. Then I found that it works for me only when I type docker-compose instead of docker . So docker-compose version or docker-compose images worked for me as well, as any other command.

Answer 20

不幸的是，经过多次尝试和重新启动，我卸载了 docker 并重新安装了它，我不得不重新构建所有东西。

我遇到了同样的问题，我在 Powershell 中尝试过它们，它可以工作 someHo

Answer 22

1. Download "docker-machine-Windows-x86_64.exe" from: https://github.com/docker/machine/releases

3. Copy "docker-machine.exe" to path C:\Program Files\Docker\Docker\resources\bin .

I facing the same issue when I try to run docker -v in Vscode Terminal after install it. I try to use cmd and git bash it work fine. Restart your vscode will solve it
