Exception in thread “main” io.appium.java_client.service.local.InvalidServerInstanceException: Invalid server instance exception has occured: There is no installed nodes! Please install node via NPM (https://www.npmjs.com/package/appium#using-node-js) or download and install Appium app (http://appium.io/downloads.html)

Node Is Installed in my system Via Brew

@mykola-mokhnach @Aleksei @rgonalo Please help me to rectify this.

share the code which you are using to start appium service.

Tahir_Akhlaq · February 12, 2019, 9:49am

Below Is the Following Code:
private AppiumDriverLocalService service;
private AppiumServiceBuilder builder;
private DesiredCapabilities cap;

public void startServer() {
	//Set Capabilities
	cap = new DesiredCapabilities();
	cap.setCapability("noReset", "false");
	
	//Build the Appium service
	builder = new AppiumServiceBuilder();
	builder.withIPAddress("127.0.0.0");
	builder.usingPort(4723);
	builder.withCapabilities(cap);
	builder.withArgument(GeneralServerFlag.SESSION_OVERRIDE);
	builder.withArgument(GeneralServerFlag.LOG_LEVEL,"error");
	
	//Start the server with the builder
	service = AppiumDriverLocalService.buildService(builder);
	service.start();
}

try the buildDefaultService(), to check if default appium service is working.
AppiumDriverLocalService service
service = AppiumDriverLocalService.buildDefaultService();
service.start();

I’ve already tried this ,it also giving me the Same Error.
io.appium.java_client.service.local.InvalidServerInstanceException: Invalid server instance exception has occured: There is no installed nodes!

I’m guessing it could be a Path Problem,which i’m not getting exactly where is the mess

to me it looks a permission issue, uninstall node and reinstall without using sudo or you can give the node path to Appium service builder.

take a look at AppiumServiceBuilder class in java client, also i checked path on my machine it shows /usr/local/bin/node

public final class AppiumServiceBuilder extends Builder<AppiumDriverLocalService, AppiumServiceBuilder> {
public static final String APPIUM_PATH = “APPIUM_BINARY_PATH”;
public static final String NODE_PATH = “NODE_BINARY_PATH”;
public static final String DEFAULT_LOCAL_IP_ADDRESS = “0.0.0.0”;
private static final List PATH_CAPABILITIES = ImmutableList.of(“keystorePath”, “chromedriverExecutable”, “app”);
private static final String APPIUM_FOLDER = “appium”;
private static final String BUILD_FOLDER = “build”;
private static final S

@Tahir_Akhlaq i am installing appium with “npm”. and i start appium using any java executor and “appium” command.

You have to set the environment variables in Eclipse:

Tahir_Akhlaq · February 13, 2019, 6:48am

@wreed Still getting the same error.
Why it’s working fine while starting manually.

Venkatesh · February 13, 2019, 7:11am

Ahh…I remember used to get these errors in eclipse, it would not even recognise adb. Intellij Works like a charm !!

Tahir_Akhlaq · February 13, 2019, 7:43am

so i should try in Intellij??

Venkatesh · February 13, 2019, 8:55am

Give a try, that should resolve the issue.

Tahir_Akhlaq · February 13, 2019, 9:48am

Getting the same Error On Intellij Too ! @venkatesh

@Tahir_Akhlaq

Try installing node from https://nodejs.org/en/download/
and then give another run.

wreed · February 13, 2019, 8:18pm

2 REALLY BIG problems with your setup.

NODE_HOME. Really? Where did this come from? I think you should add node’s location to your PATH variable. I did a quick search for NODE_HOME and couldn’t find any reference to that. Don’t just make stuff up and expect it to work.
/usr/bin/node. That is not the path. When giving a path you only need to specify the directory node is inside of. So if it’s really inside /usr/bin, that’s all you should need. However, on my Mac the path is /usr/local/bin/node, which would make the path /usr/local/bin <-you can find where node lives by typing: which node in the terminal.

If you don’t understand environment variables please read this:

@wreed @Aleksei

I am facing the same/similar issue.
I am using IntelliJ IDEA 2022.1.4 (Community Edition)
Which node returns: /Users/venkatanutalapati/.nvm/versions/node/v18.12.0/bin/node
I defined a variable NODE_PATH=/Users/venkatanutalapati/.nvm/versions/node/v18.12.0/bin
and my path:
export PATH=/bin:/usr/bin:/usr/local/bin:${NODE_PATH}:/usr/sbin:/sbin:/usr/local/bin/appium:${JAVA_HOME}/bin:${GRADLE_HOME}/bin:$PATH

I am trying to start the appium programmatically like this:
*public AppiumDriverLocalService GetAppiumService() {
* GlobalParams params = new GlobalParams();
* return AppiumDriverLocalService.buildService(new AppiumServiceBuilder()
* .usingAnyFreePort()
* .withArgument(() -> “–base-path”, “/wd/hub”)
* .withArgument(GeneralServerFlag.SESSION_OVERRIDE)
* .withLogFile(new File(params.getPlatformName() + “_”
* + params.getDeviceName() + File.separator + “Server.log”)));
* }

I am getting the following error when I run my testing.xml file

io.appium.java_client.service.local.InvalidServerInstanceException: NodeJS is either not installed or its executable not present in PATH

at io.appium.java_client.service.local.AppiumServiceBuilder.validatePath(AppiumServiceBuilder.java:124)*

BTW, my appium version is [email protected]
Please help, where I am making the mistake.

Error gone:
Sometimes, when using Node Version Manager like nvm being used to install and maintain node and npm , you may need to download and install the same or higher version of node/npm being downloaded(in pkg form) from nodejs.org.

But new error came up, which is posted here
