aproba | A ridiculously light-weight function argument validator | Validation library

I'm trying to test out the fabcar example from IBM (https://github.com/IBM/fabcar-blockchain-sample). This is something that I've done before on my computer and it worked. I have installed windows-build-tools and can see that Python 2.7 is installed. Npm install in web-app -> server give the following response:

What am I doing wrong?

I want to copy a file called default.conf to my container.

For that I have a dockerfile with COPY default.conf /opt/default.conf

The default.conf file is in the same directory like my dockerfile

When I execute the dockerfile it says:

Step 3/9 : COPY default.conf /opt/default.conf

---> 6529590ff51e

BUT when I go into the container with docker exec -it [container-id] /bin/sh

There is no default.conf

Dockerfile:

I've built a Rails 6 app that uses React as a frontend and using Bootstrap React for my styling components. Everything works fine locally but when I deploy to Heroku and I try to create an 'outage', it throws the following error:

This is quite strange problem. I believe it was not in there before (in previous versions of yarn or it's some package problem). I'm using yarn on MacOS and deploy application to live server. Yarn on both is latest 1.12.1

On localhost:

1. I removed node_modules directory
2. I removed also yarn.lock
3. I run yarn install to install all fresh dependencies

Now I deployed code to live server (with yarn.lock) and:

1. I removed node_modules directory
2. I run yarn install to install all fresh dependencies - it should use yarn.lock and not modify it

The problem is that on live server yarn.lock file is modified.

When I run git diff I'm getting (beginning of diff):

When I run npm install I see a lot of this:

I see this on two different machines. When I navigate to the folder that contains my package.json file and execute the command yarn list, it lists a bunch of packages that I haven't installed. If I execute the command yarn check then it complains that most of the packages aren't installed.

So, what changed since the last time this worked correctly? Where is yarn finding all of the extraneous packages, and how do I convince it that they really aren't there?

Here are all of the relevant files in my project directory:

I am trying to init a new react native project via the React Native CLI. I am on the most recent version (2.0.1)

Then, I run the standard React Native Init command and the new project builds with all of these unmet peer dependency warnings:

I always use to develop my projects natively for Android and iOS, but after many people talking to me about react-native, I decided to give it a try.

However, I got very frustrated at the very first initial step: create my first project.

This is my environment:

• macOS Mojave 10.14
• Xcode 10.0
• node v10.12.0
• watchman 4.9.0
• react-native-cli: 2.0.1

When I run the command react-native init AwesomeProject, I see many warnings like this:
