I wanted a mean starter kit so that I can build my app. Then I got this from github. I just made it setup then made npm install and then made npm start. But it showed me several errors like this
[nodemon] 1.12.1

So can someone tell me how to make this working? Any help and suggestions will be really appreciable.

After running the install script, the server starts and serves a page displaying the same text after the 'Failed to compile line.'
I'm running Windows 10 and auto update just updated my pc today, right before I did the create-react-express install.

Seems to be an issue with autoprefixer latest version. I referred https://github.com/postcss/autoprefixer/issues/1328 and tried downgrading autoprefixer in my project and it works now.
Try:
npm install autoprefixer#9.8.0
Happy coding!
I also faced this problem. And it looks like a problem with autoprefixer version, so i changed the version.
npm install autoprefixer#9.8.0
I tried this, and it works perfectly.
I was running into this issue too. I installed yarn and created a new project with the npx create-react-app command and this fixed the issue.
I found one project on GitHub darkwire and wanted to install it and play with it. Firstly I tried to install it from windows. I installed Node.js and Yarn and I got errors with the command: yarn dev
`C:\darkwire.io-master>yarn dev
yarn run v1.21.1

My next step was to try it in ubuntu 19.10, firstly I installed again Node.js and Yarn and again used: yarn dev. I got an error but now was open site and it not working, just say "Disconnected"
```qq#ubuntu:~/Downloads/darkwire.io-master$ yarn dev

I think maybe I have the wrong version Node.js and try install 9.x version, download again project and try again, it not help, try change port from 3001 to 3000, not help.
From their README.md
Darkwire Server
Darkwire server is a Node.js application that requires redis.
So please install a compatible redis server. Redis tutorial
I am trying to run nodemon on my local pc.
Even if i just run the command without parameters i get the following error:
events.js:182
throw er; // Unhandled 'error' event

(Note - paths in above error altered to remove my username)
I have tried the basics, restarting my pc, checking if another app is using port 3000 (i dont think it is).
Any help or advice would be appreciated
Nodemon simply starts command "node app.js", if start node ok, it'll track files changes and restart node process.
Your error seems to cause by lack of nodejs configurations.
Try to check node program directory path is included in PATH variable or not.
In the windows pc, there're steps:
Find node install folder, commonly in C:\Program Files\nodejs or C:\Windows\System32\
Check this folder path in PATH variable value.
I installed the seed app here: https://github.com/moizKachwala/Angular2-expressjs-mongoose-gulp-node-typescript
I'm trying to run npm start but the server is not being created and started.
I thought maybe this line "(node:16596) fs: re-evaluating native module sources is not supported. If you are using the graceful-fs module, please update it to a more recent version" was the issue and I found that on SO its was suggested to make sure you have latest npm which I do.
NOTE: The gulp script is supposed to create the dist folder where it will place all the js files but the dist folder is not being created so the gulp script is failing somewhere...
What else could it be?
c:\work\angular\pricecompare1>npm start
> angular2-express#1.0.0 start c:\work\angular\pricecompare1

I'm writing my second MEAN app. The first one was build aggregating the components by hand (I was not aware of MEAN) and hosting it at HEROKU; I attempted to use MONGOOSE but gave up due to problems connecting with the database at HEROKU - it worked fine on my MAC. This time around it works on my MAC but I'm still having connection problems; I do not want to jettison MONGOOSE. At this point all I have is the vanilla MEAN app built off its zip file, the zip file downloaded from the MEAN GitHUB repository. See below for the logs I get from HEROKU:

Any comments of suggestions would be much welcome. Thanks in advance.
You need to host MongoDB somewhere. There are a number of MongoDB hosting services, MongoHQ and MongoLab the most popular. I have used MongoHQ with good results although I must admit I haven't stressed my system. You can sign up for the free trial (I think you get 512MB), once you have done that, replace your connection string with (you will get all the details when signing up):
'mongodb://username:password#domain:port/dbName'
