C#Bot Setting Up Your Development Environment: Linux
This article will guide you through the installation of C#Bot’s core prerequisite dependencies, which should take approximately 5-10 minutes. These are the core dependencies you will be installing:
- NET 5 SDK
- Node Js
- dotnet-ef 5.0
.NET 5 SDK
.Net Core SDK is a software development kit for building and developing C# applications (like those written by C#Bot).
Make sure you download .Net 5 and not .Net 6, as the bot has not been upgraded yet.
To install the .Net 5 SDK:
- Go to Microsoft .Net Core Download
- Using the in-article menu on the right side of the page, navigate down to your Linux distribution (i.e. Ubuntu)
- Choose the version of your distribution (i.e. 21.10)
- Follow the instructions provided for the version that you are linked to
Installing Node.js, npm or nvm on linux is easily done with one command from bash terminal.
Open the bash terminal. Run the following command to update the packages index:
sudo apt update
Install node and other supporting packages by running the following command:
sudo apt install nodejs npm curl
Verify that the installations worked by running the following command:
nodejs --version npm --version
Update node to version 14.16.0.
sudo npm install -g n sudo n 14.16.0
Install nvm. The
curlcommand is used for nvm installation.
curl -o- https://raw.githubusercontent.com/creationix/nvm/v0.33.11/install.sh | bash
Close and re-open the bash terminal, and verify that the nvm installation worked.
Change your active Node version to 14.16.0
nvm use 14.16.0
PostgresSQL 10 can be installed by using the following command in the linux terminal:
sudo apt-get install postgresql-10
PostgreSQL should now be installed on your machine.
Setting the superuser password
The default password for the PostgreSQL superuser should be set to
pass to allow the Entity Framework Database Connection String to work.
If you don’t wish to set the superuser password here, there are steps in Running C#Bot (under the
First Time Setupsteps) for reconfiguring the database connection string to suit pre-existing PostgreSQL user configuration.
Open Terminal and execute the following commands:
sudo -u postgres psql postgres \password postgres
Enter new password: Enter it again:
pass to set the password to ‘pass’.
pgAdmin is a useful database explorer that works with PostgreSQL. It comes installed with postgreSQL in the enterprisedb package which was installed in the above section.
To access pgAdmin, search your applications list for ‘pgAdmin’. pgAdmin is a browser-based application and will launch in your web browser. You can use this tool to modify database tables and configurations.
dotnet-ef is a package of Entity Framework Core tools for the .NET command line. It is used to create and apply database migrations after making model changes.
To install it, open bash and run the following command:
dotnet tool install --global dotnet-ef --version 5.0
You can verify the installation by running the command below:
