I just created a new meteor app (blaze) and when I try starting the app on terminal, I get this error

              Here are a couple of things to try:
  
  
    Okay, try this: 
– I think this may wipe your current mongo db, so you should export it first so as to be able to import it later if necessary.
   
 
  
  
    This is a pretty thorough reset for Meteor. It might be worth a try in your case. 
Download an entirely fresh copy of your source via  git clone
Copy the  .meteor  directory into the new project folder from the previous source folder
Run  meteor reset  and  meteor update  (Make sure to have copies of your mongodb files so as to upload them again to local mongo after the  reset )
Uninstall Mongo from your local dev system and re-installed it
Run  mongo --shell  in the terminal to access the mon…
   
 
             
            
               
               
               
            
            
                 
                 
              
           
          
            
            
              This is a new project I just created, so there is nothing in the database
but all the same, I have run the meteor reset all the same and it didn’t solve the problem
             
            
               
               
               
            
            
                 
                 
              
           
          
            
            
              It just keeps showing "Unexpected mongo exit code 127
             
            
               
               
               
            
            
                 
                 
              
           
          
            
            
              Hi @koakpet , can you provide the information below so I can help you figure out what is going on
Node version 
Meteor version 
OS and OS version 
MongoDB version
What did you use to install Meteor and which command are you running
             
            
               
               
               
            
            
                 
                 
              
           
          
            
            
              
You are missing cURL you need to install the libcurl package you can get the sources  via:
git clone https://github.com/curl/curl.git
But best to use your package manager, as I don’t know your distribution here’s all the ways you can get it (remember to run an update first to get the latest and greatest)
Ubuntu: 
$ sudo apt update && sudo apt upgrade 
$ sudo apt install curl
Freebsd: 
$ sudo pkg update && sudo pkg upgrade 
$ sudo pkg install curl
CentOS / RHEL: 
$ sudo apt-get install curl
Gentoo: 
$ sudo emerge curl
Suse: Install cURL on openSUSE using the Snap Store | Snapcraft 
Enjoy
             
            
               
               
               
            
            
                 
                 
              
           
          
            
            
              thank you so much
I use Ubuntu, immediately I ran the commands you shared, my problem was fixed
