An open port could not be located on the x86_64-conda_cos6-linux-gnu system

Recently delved into learning React and encountered some challenges that I could use assistance with. I am in the midst of developing an application using this code snippet:

npx create-react-app project-name

Upon creating the application, I ran into issues when I attempted to launch it using:

npm start

The error message that popped up read: "Could not find an open port at x86_64-conda_cos6-linux-gnu."

If someone could provide me guidance on how to resolve this issue, I would greatly appreciate it. Thank you.

Here's the log message for reference:

"Attempting to bind to HOST environment variable: x86_64-conda_cos6-linux-gnu If this was unintentional, check that you haven't mistakenly set it in your shell. Learn more here: "

node.jsreactjsnpmnpm-installnpx

Answer №1

Finally figured it out! All I had to do was enter

RUN_HOST=localhost npm start

and now everything is running smoothly

Answer №2

To solve the issue:

  1. I added HOST="localhost" to my ~.bash_profile file using nano in my command line editor
  2. Next, I refreshed the environment variables by running source ~/.bash_profile

Here are specific steps for Ubuntu users:

  1. Change the hostname using hostnamectl.

    In Ubuntu 18.04, you can adjust the system hostname and related settings with the command hostnamectl.

For instance, to change the static hostname to linuxize, execute this command:

sudo hostnamectl set-hostname localhost

The hostnamectl command will not display any output but will return 0 upon success.

  1. Edit the /etc/hosts file. Open the /etc/hosts file and update the old hostname to the new one.
/etc/hosts
127.0.0.1   localhost


# The following lines are desirable for IPv6 capable hosts
::1     localhost ip6-localhost ip6-loopback
ff02::1 ip6-allnodes
ff02::2 ip6-allrouters

Then proceed to step 3 by editing the cloud.cfg file.

If the cloud-init package is installed, make sure to edit the cloud.cfg file as well. This package is typically included by default in images from cloud providers like AWS, used for initializing cloud instances.

To confirm if the package is installed, run the following ls command:

ls -l /etc/cloud/cloud.cfg
