Apple Silicon + CRA - reactjs

I have Mac Apple Silicon. I try to start the CRA app, but it's crashing. But my old projects work successfully. I don't do anything that can crash my system preferences or something else.

Try using nvm to install LTS version (see https://nodejs.org for more details) and use it to run the CRA:
Install nvm
restart terminal
nvm install --lts
`npm start

Centos 7 how to instal old epel repository to get php5 mssql_* functions

I need to install web server for older intranet app - it requires mssql library (I know its old, but nobody will redevelop the app).
In Centos 7 I was installing it like this (along with vesta - also old)
yum install epel-release
yum install php-mssql
And that is it - it worked great, but now while I try to install it it says mssql was removed and replaced with pdo.
I tried to install the mssql library directly:
sudo yum install wget https://download-ib01.fedoraproject.org/pub/epel/7/x86_64/Packages/p/php-mssql-5.4.16-9.el7.x86_64.rpm
But there was a problem with dependencies I could not solve (It requires X and X require Y and then Z.... and so on).
My idea is not to install newest epel release but to download older one install it. Is it possible? I have found old repository but how to install it? (its list of modules, how do I install them all to get dependencies)
https://dl.fedoraproject.org/pub/archive/epel/
Or maybe there is other idea to install mssql functions?

The app build fails when using React Native CLI

I am very fustrated. The React Native CLI is failing when building the app.
** BUILD FAILED **
The following build commands failed:

I did uninstall Xcode and install it fresh but did not make any difference, I got exactly the same error. The errors seem to be related with the Flipper library, but Flipper is installed as a pod in the ios/Pods directory.
Yesterday I tried Expo. The installation of the expo CLI took forever and it got hanging in the iTerm window, so I kill it. But then, when typing “expo whoami”, it gave me the asnwer of “Not logged in”, which means that Expo was installed. I was able to run the app in the ios simulator.
Today, when I tried to run the app again, I got the message that Expo was not installed. Weird, since I used it yesterday. I did the Expo cli installation again today and it did the same than yesterday. It has been more than 3 hours hanging in the terminal. But when I type “expo whoami”, I get the correct answer and I am able to run the app.
Also, today I did install the latest version of Android Studio 4.1.2 (I had version 1.3). After installation, Android Studio opens a window and then quits. I researched and it seems like Android Studio does not work on Mac version greater than 10.14 (Mac OS Mojave).
Why I am having so many problems just to run the app?. Anybody else having these problems?. Any solutions?.
If you are not using flipper just comment it out on the Podfile, that fixed the issue for me,
How to do it,
open podfile and make sure all this is commented,
# Enables Flipper.
#
# Note that if you have use_frameworks! enabled, Flipper will not work and
# you should disable these next few lines.
# use_flipper!
# post_install do |installer|
# flipper_post_install(installer)
# end
update pods
pod update
That will fix it,
If you need flipper you'll have to specify use_flipper!({ 'Flipper-Folly' => '2.3.0' }) version and run pod install

Installing typescript definition manager

Hi I am trying to install the typescript definition manager (TSD) on my Ubuntu 14.04 VM. I am following the '5 minute tutotial' from Angular.
It says to run
npm install -g tsd#^0.6.0
After that I am supposed to run
tsd install angular2 es6-promise rx rx-lite
Anyway, after running the last command Ubuntu simply returns
tsd: command not found
Can anyone help here?
Can you run the npm install -g tsd again, it should output the location where it installs it for you.
In this case that location isn't added to your path variable and you should use a absolute location (or add it to your path).
You should be able to do this in ubuntu by creating a ~/.profile file with
export PATH=$PATH:/path/to/tsd/folder/
The problem in my case seemed to be the nodejs version on my Ubuntu VM. I created a new VM and installed nodejs the following way
cd /usr/local/src
wget http://nodejs.org/dist/v0.12.7/node-v0.12.7.tar.gz
tar -xvzf node-v0.12.7.tar.gz
cd node-v0.12.7
./configure
make
sudo make install
which node
After this I could run
tsd install angular2 es6-promise rx rx-lite
and everything worked as expected. SO I believe updating the my nodejs was the solution. It seems that my old nodejs did not add tsd to the path
Can anyone help here?
Check your node version. Recommend you use latest iojs. It works as shown :

Update to last version after already installed old

I'm using fastcgi and my PHP version is 5.3.3 instead of 5.5 so my question is how can I update to latest PHP version? I'm using CentOS, I tried yum update, but no update appeared for this.
Normally you need to uninstall the 5.3 branch and install 5.5 from scratch because it is not an update but a new version.
Beware that in 5.5 quite some functions are deprecated that were still available in 5.3!

Uses the remi repository.
From the blog:
By running the following commands:
rpm -Uvh http://download.fedoraproject.org/pub/epel/6/i386/epel-release-6-8.noarch.rpm
rpm -Uvh http://rpms.famillecollet.com/enterprise/remi-release-6.rpm
you solve all dependency issues with epel and remi on CentOS 6.
Then, by running the following command, you install PHP 5.5.
yum --enablerepo=remi,remi-test install httpd php php-common
For extra goodies, you can run the following command:
yum --enablerepo=remi,remi-test install php-pecl-apc php-cli php-pear php-pdo php-mysqlnd php-pgsql php-pecl-mongo php-sqlite php-pecl-memcache php-pecl-memcached php-gd php-mbstring php-mcrypt php-xml
Now, restart your httpd service and set it to boot automatically:
service httpd restart
chkconfig --levels 235 httpd on
Now run:
php --version
to see whether the correct version of PHP was installed.

Mac Ports Update Failing

hansarijanto$ port -v
MacPorts 2.0.3
hansarijanto$ xcodebuild -version
Xcode 4.3.2
Build version 4E2002
I am running the above xcode and macport version. on max os x
when I try to self update my mac port I get the following error.
hansarijanto$ sudo port selfupdate
Password:

I am trying to update mac port to install qt.
sudo port install qt4-mac-devel(error no SDK found)
which I need to install webkit-capybara
sudo gem install capybara-webkit -v '0.7.2'(error in setting up native environment)
You need to use the -d option to get enough information to diagnose this; but take a look at https://trac.macports.org/wiki/FAQ#selfupdatefails for common problems and solutions.
Seems Apple no longer installs Xcode's command line tools. See here: http://ericwilson.erics.ws/ericsblog/2012/8/26/macports-port-selfupdate-fail for solution.
Just wanted to add that on Mac OS 10.12 Sierra i was getting the WARNING: GNUSTEP_SYSTEM_ROOT is not defined error on selfupdate and i did already have the Xcode command line tools installed, licensed and working. But my copy of Xcode had become out of date, even though that was not showing up on the automatic software updates.
I had version 7 and for Sierra (and macports) you need version 8.
So I manually downloaded Xcode 8 via the App Store and it solved the problem for me.
