I'm getting into Hyperleadger Indy for a project and want to set it up as a clean docker container. Its often pretty confusing with correct sources of documentation.
As a start i wanted to follow the tutorial based on Alice.
I used https://github.com/hyperledger/indy-sdk/ as a repository and installed it with commands from https://github.com/hyperledger/indy-sdk/#how-to-start-local-nodes-pool-with-docker.
Everything worked but when i try to enter the CML this happens:
indy#a1265007869d:/$ indy
Loading module /usr/local/lib/python3.5/dist-packages/config/config-crypto-example1.py
Module loaded.
This client is deprecated! Please, use the new libindy-based CLI: https://github.com/hyperledger/indy-sdk/tree/master/cli
Indy-CLI (c) 2017 Evernym, Inc.
Type 'help' for more information.
Running Indy 1.4.66
Any command throw:
Exception in callback PosixAsyncioEventLoop.run_as_coroutine.<locals>.stdin_ready() at /usr/lib/python3/dist-packages/prompt_toolkit/eventloop/asyncio_posix.py:65
handle: <Handle PosixAsyncioEventLoop.run_as_coroutine.<locals>.stdin_ready() at /usr/lib/python3/dist-packages/prompt_toolkit/eventloop/asyncio_posix.py:65>
Can someone maybe also explain when to use Indy-Node and when Indy-SDK and are they independent?
Embedded indy-node CLI is deprecated now. There are two options:
Try another terminal client or the same client with different window size
Move to CLI from indy-cli separated package. You cand find it here https://github.com/hyperledger/indy-sdk/blob/master/cli/README.md

I installed Phalcon PHP as described in https://docs.phalcon.io/3.4/en/webserver-wamp.
In this case the URL reads 3.4 because it applies alike for versions 4 and 5.
The WAMP server version is 3.2.6 configured with PHP 8.0.13
Everything was fine so far, so I continued installing the developer tools using composer as described in https://docs.phalcon.io/5.0/en/devtools.
Composer was installed globally and so were the developer tools, but when I type "phalcon" in the command window, the following error is shown:
C:\>phalcon
Fatal error: Uncaught Error: Class "Phalcon\Script" not found in C:\Users\Joachim\AppData\Roaming\Composer\vendor\phalcon\devtools\phalcon.php:38
Stack trace:
#0 {main}
thrown in C:\Users\Joachim\AppData\Roaming\Composer\vendor\phalcon\devtools\phalcon.php on line 38
C:\>
PSR and Phalcon extensions were successfully installed and I can see them in the WAMP Localhost page.
The Path environment variable contains the path to phalcon, composer, wamp, etc, nothing is missing as far as I can see.
Have anyone dealt with this error?
What could be the problem?
I'm a bit late answering this, but in case anyone else stumbles across it via Google the problem is that some namespaces have been altered between Phalcon4 and Phalcon5. I believe Phalcon\Config is one of those classes.
Until the devtools have been updated for Phalcon5, you'll either need to build the scaffolding manually, or copy an old Phalcon 3 or 4 project and update the namespaces.
The perils of using alpha/beta releases, unfortunately.
you didn't mention which phalcon version but since you are using php 8 the only version supporting php 8 is phalcon 5
your issue is most likely in your php.ini for the cli since wamp uses different files for apache and cli.
to fix the issue first remove the devtools package you installed globally then edit the cli php.ini in [wampDir]\bin\php\php8.0.13\php.ini and include psr and phalcon and install the devtools again using composer
you can also download the phar file here and test it in the cli
php phalcon.phar
I was trying to follow this tutorial:
https://docs.opensea.io/docs/1-structuring-your-smart-contract
And even found this extremely helpful YouTube video to guide me:
https://www.youtube.com/watch?v=lbXcvRx0o3Y&ab_channel=DanViau
But I've encountered a problem after installing and setting up everything I needed. The problem occured when I tried to deploy the contracts using this bash command:
truffle deploy --network rinkeby
The error message I got is:
Error: There was a timeout while attempting to connect to the network.
Check to see that your provider is valid.
If you have a slow internet connection, try configuring a longer timeout in your Truffle config. Use the networks[networkName].networkCheckTimeout property to do this.
at Timeout._onTimeout (C:\Users\alonb\.nvm\versions\node\v12.22.5\bin\node_modules\truffle\build\webpack:\packages\provider\index.js:56:1)
at listOnTimeout (internal/timers.js:554:17)
at processTimers (internal/timers.js:497:7)
It's not caused by slow internet connection - I know that because I have tried executing this command on 3 different WiFi connections, one at 200 Mb/s rate.
I have tried to change the truffle-config.js file and add a longer timeout threshold (like suggested here), but the only thing that changed was that the error message took much longer to appear.
Technical info - I'm using Git Bash, npm version 6.14.14, nvm version 0.38.0, node version 12.22.5.
Any suggestions? I'm lost.

I also ran into this error when following the same tutorial.
I use Alchemy (not Infura), and the issue was my API_KEY.
In other tutorials I've followed, the scripts require the full alchemy API Key (ex. "https://eth-rinkeby.alchemyapi.io/v2/<random-key>").
So, when I was following this tutorial, that is what I supplied. And, I ran into the error you reported.
But when I reviewed the truffle.js script provided by the tutorial authors, I found this:
const rinkebyNodeUrl = isInfura
? "https://rinkeby.infura.io/v3/" + NODE_API_KEY
: "https://eth-rinkeby.alchemyapi.io/v2/" + NODE_API_KEY;
Thus, the script was producing:
rinkebyNodeUrl = https://eth-rinkeby.alchemyapi.io/v2/https://eth-rinkeby.alchemyapi.io/v2/<**random-key**>
...which is clearly wrong.
Thus, ensuring I set my API_KEY environment variable only to random-key and not https://eth-rinkeby.alchemyapi.io/v2/https://eth-rinkeby.alchemyapi.io/v2/<random-key>, my contract deployed successfully.
Also, make sure you have enough ETH in your wallet on the Rinkeby network. Faucets always seem to work for a little while then stop working, so do some Google searches to find one that is currently functional.
The solution is incredibly easy -
Instead of using just the relevant part of the Alchemy key:
40Oo3XScVabXXXX8sePUEp9tb90gXXXX
I used the whole URL:
https://eth-rinkeby.alchemyapi.io/v2/40Oo3XScVabXXXX8sePUEp9tb90gXXXX
I had the same experience but when using hardhat not truffle.My internet connection was ok,try switching from Git bash to terminal(CMD).Use a completely new terminal avoid Gitbash and powershell.
Remove the function wrapper from provider inside the network configuration.
ropsten_infura: {
provider: new HDWalletProvider({
mnemonic: {
phrase: mnemonic
},
providerOrUrl: `https://ropsten.infura.io/v3/${project_id}`,
addressIndex
}),
network_id: 3
}
The rinkbery network has been decommissioned. Use Goerli or Sepolia network. Update your truffle config add a section for goerli in networks. E.g
goerli: {
provider: () =>
new HDWalletProvider(
mnemonic,
`https://goerli.infura.io/v3/${INFURAKEY}`
),
network_id: 5, // goerli's id
gas: 4500000, //
gasPrice: 10000000000,
}
The run the command
truffle deploy --network goerli
I tried to install Neos CMS local under Windows 10 with a Wamp Apache Server. After creating the project with a composer and registering the Vhosts, I tried to run neos.demo/setup. Then I get an 500 internal server error with the message "Specified path not found”, for more information, take a look at the screenshot.
I checked the solutions for the exception code 1355480641, but nothing can solve my problem.
Thanks for your recommendations!
do you have set Neos.Flow.core.phpBinaryPathAndFilename in Configuration/Settings.yaml to the correct php.exe binary path?
This is not an actual solution, this is more of an alternative.
I was having troubles installing neos on windows 10 as well (not the same as you though), a really nice solution that I would recommend as alternative to wamp is bitnami-neos.
I got the same error in the current version of Neos CMS (v4.1). The solution to the problem was for me:
Adjust Configuration/Settings.yaml with the php.exe path (which you already did)
Launch an administrator cmd
Go to the Neos CMS directory
Run flow flow:core:compile
Run flow flow:cache:warmup
Now I could access Neos with XAMPP.
All credit for this answer goes to the following post: https://discuss.neos.io/t/running-neos-flow-on-windows-10-success/2752
I am trying to run a .tcl file originally configured for 2014.4 on 2016.4 version of Vivado. However I am getting the following error:
while executing
"create_bd_cell -type ip -vlnv xilinx.com:ip:mig mig_0 "
(procedure "create_root_design" line 111)
invoked from within
"create_root_design """
(file "all.tcl" line 405)
The tcl file uses the part 'xcku040-ffva1156-2' and tries to access the IP 'mig' which I believe is renamed/changed on later versions. Is there any workaround for this?
Steps I have done till now:
Changed the version number to 2016.4
tried replacing target boards.
tried on the same board with an alternate IP for mig.
tried on both 2016.4 and 2015.4 versions
None of these have worked so far
Attaching the '.tcl' file for reference : all.tcl
Since with every version upgrade of the Vivado Design Suite, parts are renamed or removed, it is not possible to run a .tcl file meant for an earlier version in newer releases. So I ran the above query on Xilinx Community Forums and found a workaround:
Run this script on the previous version(2014 in this case), generate the design and then open the same design using the next major release(2015 version). The 2015 version will automatically suggest upgrades to the discontinued/renamed IPs. Repeat the same to get to 2016 version. That's the only way to get this done. Also have to keep checking if the core functionality of the IP is the same after automated upgrades by Vivado Design Suite.
I have created MSI package using advanced Installer. It contains App Config to which i have to pass the siteURL which varies depending on location. I need to pass the siteurl to app config when msi is installed . Please help me with it. I am new to Advanced Installer
You can check the online user guide for Advanced Installer, it has a lot of useful info. For example the article on importing and editing XML config files.
Or how to add a custom dialog and write in the system the values captured from the end users.
EDIT: additional answer regarding command line
You can run the installation silently from the command line but you will still see the message box saying the package is built with a trial. You will not see the standard MSI dialogs. And the trial messages will be gone once you purchase license for Advanced Installer.
Please note that your command prompt window (cmd.exe) must be launched as administrator, if your installation is installing per-machine (i.e. you write in Program Files or HKLM registry hive). Otherwise the installation will fail silently and you will not know why, because on silent installation the OS will not show an error message.
Here is a command line example:
msiexec.exe /i C:\setup\installer.msi /qn ID="235424" SiteURL="www.example.com"
Please note that it is not recommended to use private properties, i.e. properties with lower case letters in their name, we recommend public properties, for example: SITE_URL.
