NOTE: This error is almost always caused because the command does not exist, because the working directory does not exist, or from a windows-only bug. The problem of this error is, there is really little information in the error message to tell you where the call site is, i.

On the other hand, if we know the exact command that cause the error then we can follow laconbass' answer to fix the problem. I found a very easy way to spot which command cause the problem rather than adding event listeners everywhere in your code as suggested in laconbass' answer.

The key idea is to wrap the original spawn call with a wrapper which prints the arguments send to the spawn call. Here is the wrapper function, put it at the top of the index.

Then the next time you run your application, before the uncaught exception's message you will see something like that:. In this way you can easily know which command actually is executed and then you can find out why nodejs cannot find the executable to fix the problem. Launches a new process with the given commandwith command line arguments in args. If omitted, args defaults to an empty Array.

Use env to specify environment variables that will be visible to the new process, the default is process. Ensure you are not putting any command line arguments in command and the whole spawn call is valid. Proceed to next step. After debugging, that handler can be removed. Execute and you should get the file path and line number where your 'error' listener was registered.

Something like:. You must identify the listener that emits the error before going on next step. In both scenarios, you must inspect the PATH key on the environment object that the spawned child process will use. The absence of PATH i. When PATH is correctly set, proceed to next step. It should be a directory, or a list of directories.

Last case is the usual. Locate the exact place of command. On most linux distributions, this can be done from a terminal with the which command. It will tell you the absolute path to the executable file like aboveor tell if it's not found. Refer to each command documentation if needed and install it.

When command is a simple script file ensure it's accessible from a directory on the PATH. If it's not, either move it to one or make a link to it. Windows solution: Replace spawn with node-cross-spawn. For instance like this at the beginning of your app. For anyone who might stumble upon this, if all the other answers do not help and you are on Windows, know that there is currently a big issue with spawn on Windows and the PATHEXT environment variable that can cause certain calls to spawn to not work depending on how the target command is installed.

In my case, I was getting this error thrown due to the necessary dependent system resources not being installed. Despite having the npm package installed, the core Linux ImageMagick was not installed.GitHub is home to over 40 million developers working together to host and review code, manage projects, and build software together.

I just noted a project that worked has "Metro Bundler ready" listed during the startup, whereas the project that is not working has "React packager ready".

I'm not sure however how you get the "Metro Bundler" selected or what this is. Both launch. React native new versions use Metro Bundler instead. Upgrade your old project.

I take it back and now when I try to run npm start I got this error. I try to clone my repos too and get the same error. If someone can give me some way to find what happen. Thank you. You absolutely should not be installing react-scripts globally. You also don't need. This should fix the problem.

If it doesn't, please file an issue with a link to your project and versions of Node and npm. It seems like you don't have react-scripts in your global environment. Two possibility are available here :. I think i didn't use the --save when i first created the project on another machineso for me this fixed the problem :. But I got something slightly different because running npm install -g npm latest to update npm might sometimes leave you with this error:. This is to help others completely new to react and who area having problems just starting a first app even though they did a fresh install and try using npm install and the other fixes I saw around the forums.

Running it on Windows 10 with all the latest npm create-react-app installed and got failure after failure on a simple npm start in a simple my-app demo folder.

Spent a long time with what looks similar to the OP error at first but is slightly different. Eventually worked out from github create-react-app forum that a quick fix for this is registering cmd in the "path" variable.

Restart CMD prompt and I was good to go. Good luck.Author note : Lots of issues with this error encouraged me to post this question for future references. Launches a new process with the given commandwith command line arguments in args.

Update - tried adding the WSL path to System32 and although it's a pretty shonky workaround it does stop the crash:. What's strange is that I'm pretty sure CRA used to work without that path set, which suggests something changed in the way it detects the environment and launches the app in browser perhaps it was providing the path. While this workaround seems to work, I'd be a bit wary of relying on it; plus it's not particularly uncommon for WSL users to remove windows locations from their PATH.

Thanks for the update cheshrkat And you're right, I ran on WSL for two years with no issue. I'm not sure what if anything changed recently, but as I'm currently on a Mac employers choice I can't troubleshoot.

I have no idea how to reproduce this on another machine. I was able to install mongoDB on a separate computer and I don't have this issue.
