QUESTION
Does anyone have experience publishing a .NET/Angular project to Netlify? I'm using the Angular Microsoft.AspNetCore.SpaTemplates template. On Netlify, I'm getting a non-zero exit code that's preventing me from publishing. Here is my output:
...ANSWER
Answered 2019-Jan-30 at 21:21Disclaimer: I work for Netlify
As we mentioned to you in your helpdesk ticket on this same topic, our deploy environment is very naked - you have to:
- specify dependencies that we can automatically install - npm/yarn deps, bower deps, gems and python packages.
- install other dependencies yourself. the 'dotnet' program will be one of this type. We don't have it in our install environment, so you need to somehow import a copy of it into the environment. Seems like you can download the entire SDK here: https://www.microsoft.com/net/download/linux and then you need to import ONLY what is necessary for your build - it will take a very long time to build your site if we have to download the entire SDK, so see what you can trim down to get 'dotnet' to run.
For the purposes of #2, you'll probably need to test things in our build environment. How to do that, and details you'll need about the build environment such as OS type so you can download the right version of the SDK are described in this article:
https://www.netlify.com/blog/2016/10/18/how-our-build-bots-build-sites/
This will take some work on your part. It will not be trivial. It is not something we can help with in more detail than that for free customers unless you come with specific questions and examples.
To address some thoughts in the comments:
- build.sh is indeed our build script
- 9:46:52 AM: /opt/build/build.sh: line 427: dotnet: command not found means that literally there is no dotnet command available to run - not that some config file is missing.
- we only try to run it once since you have set your command to use
&&to chain several commands - one fails, the whole chain fails, and we don't need to run it two more times once the first failure occurs :)
QUESTION
I am working ona an angular project. I pushed code on git server. Another developer cloned code his own computer and run "npm install" to install node packages. And he pushed the code.
So the package.json file modified:
...ANSWER
Answered 2019-Aug-30 at 20:09Everytime someone add/updates/removes packages you should run npm install again to match your enviroment with the one described in the package.json.
UPDATE:
Also, this is not the whole story.
Recent versions of the npm tool also produce a file called package-lock.json which tells npm exactly which versionof each package it needs to install. Be sure to also put this file in your version control so that every development environment is aligned with the same versions.

I am using react-native framework for developing my android app. I want to use react-native-material-design library for making Toolbar with some more features.
I installed this library in current directory where my project is using below command :-
...ANSWER
Answered 2017-Jan-23 at 12:00try installing react-native-material-design locally instead of globally.
It looks like react-native-material-design depends on react-native-material-design-styles which won't be packaged by React Native's bundler since its parent is a global module.

I'm having some issue with using Chart.js with JSDOM in node.
I don't think it's JSDOM because i can draw on the canvas and it is rendered fine. So i suspect something is wrong with Chart.js or my usage of it.
I have this up on github also https://github.com/jacktuck/node-chartjs when it is run it will open the test.png file automatically thanks to opn
As you can see, it appears as nothing is rendered despite there being some data returned from the toBlob call on the canvas.
