I am trying to create a local chainlink oracle node, for testing and learning purposes. Using windows 10.
I followed the steps listed on the https://github.com/smartcontractkit/chainlink#install
to install a local chainlink node.
Already installed Go, nodeJS, nvm, yarn, postgres (all latest version as of 21/11/04. All ruuning from root).
Downloaded the Chainlink executing: git clone https://github.com/smartcontractkit/chainlink && cd chainlink
changed the directory to C:\chainlink
and ran make install command to build and install the node.
Got the error:
'make' is not recognized as an intern or extern command, operable program or a batch file
What am I doing wrong?
(Apparently, make install is a command that works for mac command line, I am using windows instead)
Working on Windows, the easiest method of running a node would be to use docker and download the docker image as described in the Chainlink docs.
Make is a UNIX based command and will require either using a virtual UNIX/Linux environment, using a tool like Cgywin or WSL as discussed in this post.

I cant install heroku in my kali linux operating system. how can i resolve this issue?
isn't it not possible to run heroku in kali linux?
when I have try to install, it show snap command not found.
Heroku no longer supports Snap installs:
Snap installs are no longer supported. Please use another install method below.
Since Kali is derived from Debian, you should be able to use the Debian / Ubuntu method (which doesn't auto-update) or the standalone tarball method (which does). You can also use the NPM / Yarn package if you prefer, though Heroku recommends against it.
All of these options require some amount of trust in Heroku. The first two pull a script down from the Internet and pipe it into sh, which always makes me a bit uneasy. I suspect they both request elevated privileges during the install process. Instead of piping the file directly in to sh as Heroku recommends, I suggest you download it and at least give it a quick read through the first time.
In any case, here is the command that Heroku recommends to install the standalone version:
curl https://cli-assets.heroku.com/install.sh | sh
I followed the steps on https://redislabs.com/blog/redis-on-windows-10/ and have installed Ubuntu 18.04 and am successfully running Redis v4.09 on Windows. But, when following the steps on https://oss.redislabs.com/redisearch/Quick_Start/, I have some issues.
In the download and running binaries section, I don't understand what I'm supposed to replace /path/to/module/src/redisearch.so with. I've downloaded RediSearch for Ubuntu 18.04 and I've moved the files to a folder named RediSearch within my Downloads folder. Could someone help me with the pathing considering I'm using Ubuntu on Windows? I've also tried it with Building and Running with Source section but that just runs into an error every time I run make:
*** No rule to make target 'build'. Stop.
How can I run the module with Redis?
With WSL, you have access to C: through /mnt/c/ from Linux.
So, if you really want to have redisearch on a folder in Downloads you need to use something like:
/mnt/c/Users/<yourUser>/Downloads/yourFolder/src/redisearch.so
However, you probably should use a folder within Linux instead. You can use wget to download from Linux.
I am in the process of installing jupyterhub. I successfully install jupyterhub using:
python3 -m pip install jupyterhub
npm install -g configurable-http-proxy
However, when I run jupyterhub -h in the Windows command prompt it gives:
"jupyterhub" is not recognized as an internal or external command, operable
program or batch file.
I added C:\Users\User\AppData\Local\Continuum\Anaconda3\Lib\site-packages\jupyterhub\ to my user environment variable, however still receive the message. What path should I be using?
Please note that according to this, Jupyterhub is not officially supported for Windows yet.
That aside, you could dockerize it to make your life easier. For this error, please check if you can see the executable in C:\Program Files\Continuum Analytics\Anaconda3\scripts. The lib directory you're specifying contains python source files and not the executables.
I had this same issue, and I saw this occurred because jupyterhub is a python script rather than an executable. So to run this on Windows I needed to execute it like python C:\Program Files\Continuum Analytics\Anaconda3\scripts\jupyterhub.
However, I still was unable to run jupyterhub on Windows because it depends on the pwd module, which is a Unix/Linux only module.
As others have said, Windows is not a supported platform. JupyterHub is best used on Linux-like platforms where you have Docker or something similar to conatainerize each user's session.
A good alternative is to install Oracle VirtualBox and run a local VM. I run a 64-bit Ubuntu and it's quite good performance. It makes things much easier to run JupyterHub on. Asides depending on pwd, there are also assumptions around user-creation and other activities that Windows isn't going to handle well.
In short, if you want to run on native Windows, you're going to become the first JupyterHub Windows contributor. I looked at doing it but it looked like too much effort.
The upside of running a VM is that behaviour in the VM is going to more closely resemble what you have running on the server anyway. If you don't plan running on a server, then just "jupyter notebook", as this is all JupyterHub ends up running...
I am interested in Rethinkdb and would like to develop/test on it, but main problem is: it don't have package for windows operating system. I tried to compile from source code, that was also not possible as there was no any instruction.
What makes it so difficult to make executable for windows? Is there any alternative way to install Rethinkdb in windows OS? even very small and not that famous application has windows binary but not Rethinkdb. It is quite surprise for me. Another surprising is there are many community executable for other OS but not windows.
Thank you for understanding and waiting for good answer.
Rethinkdb just announced that it started development for Windows. Please follow
[1] https://github.com/rethinkdb/rethinkdb/issues/1100
[2] https://twitter.com/segphault/status/590633792781611009
Update:
RethinkDB announced in Windows :
[3] https://rethinkdb.com/docs/install/windows/
Cross-platform development isn't that easy. RethinkDB uses some features under the covers which makes porting it to Windows a difficult job, f.e. a Unix toolchain for the builds and Unix syscalls. For more information on that have a look at this GitHub issue. It states that Windows support is planned, but with low priority.
As a quick fix, you could RethinkDB run in a virtual machine or in Microsoft Azure. For the second one, I wrote a blog post a few weeks ago.
RethinkDB has already started development for Windows. While it's not released yet, this is how you can run it through Vagrant. See: https://github.com/gearz-lab/rethinkdb-vagrant
I'm using Chocolatey, feel free to skip steps if they don't apply.
Installing Chocolatey
Open Powershell as an administrator and run this command:
iex ((new-object net.webclient).DownloadString('https://chocolatey.org/install.ps1'))
... now you should have Chocolatey installed. We're gonna use to install the others.
Installing Vagrant
Run this as an administrator:
choco install vagrant -y
Installing VirtualBox
Vagrant relies on a virtualization application that it calls a "provider". The default one is VirtualBox so let's install it. Run cmd as administrator and run this:
choco install virtualbox -y
Now you should be able to run the vboxmanage command. If it doesn't work, make sure C:\Program Files\Oracle\VirtualBox is in your PATH.
Installing Cygwin
We're gonna log on a virtual machine using SSH, so we need a SSH enabled terminal. For that, let's use Cygwin.
choco install cyg-get -y
Installing Cygwin packages
There'are two Cygwin packages we need to install, openssh, because Cygwin doesn't have SSH support by default, and rsync so Vagrant can use it to synchronize files between the host and the guest machines.
On PowerShell, running as an administrator, let's run these commands:
cyg-get openssh
cyg-get rsync
Cloning rethinkdb-vagrant
Open the Cygwin64 Terminal. You should now be in your Cygwin home folder, which should look like C:\tools\cygwin\home\[YOUR_USER].
Make sure you have git installed. If you don't just choco install git -y. Now, clone rethyinkdb-vagrant:
git clone https://github.com/gearz-lab/rethinkdb-vagrant.git
Now you should have a directory like this: C:\tools\cygwin\home\[YOUR_USER]\rethinkdb-vagrant.
Starting Vagrant and useful commands
From inside the Cygwin64 Terminal home directory (described in the last step), type cd rethinkdb-vagrant, now, any Vagrant commands will target cd rethinkdb-vagrant.
To setup and boot the machine: vagrant up (After this, RethinkDB is available, see next step).
To access the machine's terminal: vagrant ssh.
To destroy the machine (every RethinkDB data will be lost): vagrant destroy.
To suspend the machine: vagrant suspend.
To resume a suspended machine: vagrant resume.
Accessing RethinkDB.
Make sure you have vagrant up from the last step. Now:
For accessing the web administration tool: http://localhost:8080.
For accessing RethinkDB from a client app, the port is 28015.
I am having issues with the installation of scrapyd on Wndows 7 I have installed the package using easy_install, but still the command scrapyd comes up with nothing. Here is the output of my install:

Any ideas, what the issue is?
I am new here and I cannot comment. So perhaps it is not an answer but rather workaround.
Firstly, i am not sure if scrapyd works on windows at all. Please see this part of Scrapy documentation.
Personally, I develop on the Windows but deploy on Debian (where couldn't find the scrapyd package at all at the time I was working on it) and noticed that performance of scrapy is considerably worse than on linux box, so you might reconsider your target. But I digress.
However, you don't need scrapyd at all. Scrapyd is just a wrapper that keeps running scrapy server in background. To get same functionality you can run from commandline (from the scrapy project folder):
scrapy server
The scrapy server would be then running as long as the commandline is running but you can workaround this with bat file and some software to running tasks in background. Hope it helps.
Solution:
Starting scrapyd on Windows 7 [after installation] from console:
cd to Python_install_dir/Scripts and run scrapyd from python.
In my case:
1.) cd C:\Python27\Scripts
2.) C:\Python27\Scripts> python scrapyd
now you can connect to scrapyd:
http://127.0.0.1:6800/ & via console
If you wanna running the server in the background, just run this command as a windows background process.
