如何在 ubuntu 服务器上部署 vuejs 应用程序时解决剪贴板错误

Question

I am deploying a vuejs app on my server.we have EC2 instance with ubuntu 16.04,As of now I am just deploying my test project but when I go running serve command like sudo serve -s dist but it is throwing an error which is: ERROR: Cannot copy to clipboard: Command failed: xsel --clipboard --input xsel: Can't open display: (null): Inappropriate ioctl for device I don't know this error is caused by ubuntu or vuejs please help me solve it.

I have followed these cammands so far.

First installed vue cli using npm install -g @vue/cli

Then created a hello world app using vue create helloWorld

Now run serve command npm run serve

It was showing me a message like:

App running at: - Local: http://localhost:8081/ - Network: http://172.31.16.66:8081/

Now i have created a build to run an app on the production server npm run build

So my build was created successfully i run command to run the app on the live server

serve -s dist

And it is throwing an error which is not solving by me so far

WARNING: Checking for updates failed (use --debug to see full error) ERROR: Cannot copy to clipboard: Command failed: xsel --clipboard --input xsel: Can't open display: (null): Inappropriate ioctl for device

I am also attaching screenshot below.

Answer 1

As you can see, there is an X11 dependency with the serve module - which means you need an xserver(display) for it to work.

Alternatively, ( highly recommended ) you could use a high performance HTTP server like nginx , apache etc. instead.

All you need is to copy your dist folder to your instance, and point your virtual server block to the dist dir, and restart your HTTP server - BAM! you're up and running.

Cheers!

I had the same issue and I solved it by adding "-n" option to serve.

"-n, --no-clipboard Do not copy the local address to the clipboard"
