i am using nodejs --version
v0.10.25 and npm --version 5.6.0 i also installed all the required things
like node, npm ,also installed cli of react native ,android sdk, also add Android sdk into PATH, using virtual device and set device ID to udev rules.
And my file structure is :
drwxrwxr-x 5 aspl aspl 4096 Feb 16 15:17 android
-rw-rw-r-- 1 aspl aspl 1184 Feb 16 15:17 App.js
-rw-rw-r-- 1 aspl aspl 43 Feb 16 15:17 app.json

drwxrwxr-x 2 aspl aspl 4096 Feb 16 15:17 tests
still i got the error:
Exception in thread "main" javax.net.ssl.SSLException: java.security.ProviderException: java.security.InvalidKeyException: EC parameters error
Could not install the app on the device, read the error above for details.
Make sure you have an Android emulator running or a device connected and have set up your Android development environment:
https://facebook.github.io/react-native/docs/getting-started.html
The issue is due to not setting up JAVA_HOME. Set it with steps from this link .
export JAVA_HOME="/usr/lib/jvm/java-8-openjdk"
export PATH=$JAVA_HOME/bin:$PATH
save above code to your save that to your .bashrc file and run again

I compiled wayland from source code with this command
meson --buildtype=release -D prefix=$HOME/mylib -D documentation=false
then installed it with ninja. Now in $HOME/mylib I have this structure:
total 24K
drwxr-xr-x 6 myuser myuser 4.0K Dec 3 19:52 .
drwxr-xr-x 16 myuser myuser 4.0K Dec 4 17:41 ..
drwxr-xr-x 2 root root 4.0K Dec 3 19:52 bin
drwxr-xr-x 2 root root 4.0K Dec 3 19:52 include
drwxr-xr-x 3 root root 4.0K Dec 3 19:52 lib
drwxr-xr-x 4 root root 4.0K Dec 3 19:52 share
Inside bin folder I have wayland-scanner and when I run this command
wayland-scanner -v
I got this output:
wayland-scanner 1.21.90
Now when I build other source code with meson that has wayland-scanner as dependency I got this error:
../tests/meson.build:2:0: ERROR: Invalid version of dependency, need 'wayland-scanner' ['>=1.20.0'] found '1.18.0'.
This is related to another wayland-scanner that is placed here:
/usr/bin/wayland-scanner
with version 1.18.0. The command
echo $PATH
reply with this output:
/home/myuser/mylib/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/local/games:/usr/games
Why meson doesn't find the updated version of wayland-scanner? Using PKG_CONFIG_PATH doesn't work, same error as above
Hi don't know the wayland package, but from description
I could think that /usr/bin/wayland-scanner is a link to the old installation,
Try to look in your environment for the wayland-scanner scanner binary to check if there is some link do not updated to the new installation.
I install apache2 on ubuntu 18.04. This is fresh install with all default configuration.
I tried to start apache2 but failed. And this is what I see.

When I check /var/log/apache2/error.log, there is empty.
What's wrong with this error?
The "status=139" error must have something to do with having multiple, conflicting versions of PHP enabled.
I am running 18.04 and an old PHP site I run only locally ceased to work. I am guessing aptitude installed and enabled php7.2, possibly when I installed kubuntu-desktop a few weeks back.
Regardless, I had two versions of PHP enabled:
$ cd /etc/apache2/
$ l mods-*/php*

-rw-r--r-- 1 root root 855 Feb 8 2019 mods-available/php7.2.conf
-rw-r--r-- 1 root root 102 Feb 8 2019 mods-available/php7.2.load

lrwxrwxrwx 1 root root 29 May 28 06:05 mods-enabled/php7.2.conf -> ../mods-available/php7.2.conf
lrwxrwxrwx 1 root root 29 May 28 06:05 mods-enabled/php7.2.load -> ../mods-available/php7.2.load
In my case, I am fine with using php5.6, because the site is not online and is purely for my local use only. So disabling 7.2 did the trick:
sudo a2dismod php7.2
Now my php mods-enabled are less confusing to apache3:
$ l mods-*/php*
-rw-r--r-- 1 root root 867 Jun 9 2017 mods-available/php5.6.conf
-rw-r--r-- 1 root root 102 Jun 9 2017 mods-available/php5.6.load
-rw-r--r-- 1 root root 867 Mar 2 2017 mods-available/php7.0.conf
-rw-r--r-- 1 root root 102 Oct 1 2018 mods-available/php7.0.load
-rw-r--r-- 1 root root 855 Jul 7 2017 mods-available/php7.1.conf
-rw-r--r-- 1 root root 102 Jul 7 2017 mods-available/php7.1.load
-rw-r--r-- 1 root root 855 Feb 8 2019 mods-available/php7.2.conf
-rw-r--r-- 1 root root 102 Feb 8 2019 mods-available/php7.2.load
lrwxrwxrwx 1 root root 29 Jul 1 2017 mods-enabled/php5.6.conf -> ../mods-available/php5.6.conf
lrwxrwxrwx 1 root root 29 Jul 1 2017 mods-enabled/php5.6.load -> ../mods-available/php5.6.load
Naturally for a live site one would want to disable php-5.6 and leave the php7.2 enabled, because you should run the newer version in real life.
sudo a2dismod php5.6
sudo a2enmod php7.2
Then the php mods should look like this:
$ l mods-*/php*
-rw-r--r-- 1 root root 867 Jun 9 2017 mods-available/php5.6.conf
-rw-r--r-- 1 root root 102 Jun 9 2017 mods-available/php5.6.load
-rw-r--r-- 1 root root 867 Mar 2 2017 mods-available/php7.0.conf

-rw-r--r-- 1 root root 102 Jul 7 2017 mods-available/php7.1.load

lrwxrwxrwx 1 root root 29 May 29 17:43 mods-enabled/php7.2.load -> ../mods-available/php7.2.load
Don't forget to resatart the server!
systemctl restart apache2
Thanks to Pavel's comment for inspiring this line of research!
I got this error and I fixed it by enabling PHP version 8.0 (current stable) and disabling PHP version 7.4 (old) in my ubuntu 20.04 by these commands:
sudo a2dismod php7.4
sudo a2enmod php8.0
sudo service apache2 restart
After doing these check your apache status by:
sudo systemctl status apache2.service
It has to be green and must show you active (running).
NOTE: You can do this to any PHP version that you have and want to
change.
When I try to run a simple perl6 script on MSYS2-64 (bash.exe) on Windows 7 it says:
Could not open my-perl6-script.pl. Failed to stat file: no such file or directory
The same script runs perfectly fine on CMD.exe so I guess it's some incompatibility between perl6 and MSYS2.
$ perl6 -v returns:
This is Rakudo Star version 2018.04.1 built on MoarVM version 2018.04.1 implementing Perl 6.c.
The bin folder of perl6 is:

It doesn't matter if I run the script using perl6, perl6.exe or perl6.bat; they all give the same error. I'd like to run perl6 scripts on MSYS2-64. What should I do? Thanks
I installed Rakudo for Windows and made a custom perl6 shell script:
#!/bin/sh
/c/rakudo/bin/moar --execname="$0" --libpath='C:\rakudo\share\nqp\lib' --libpath='C:\rakudo\share\nqp\lib' --libpath='C:\rakudo\share/perl6/lib' --libpath='C:\rakudo\share/perl6/runtime' 'C:\rakudo\share\perl6\runtime\perl6.moarvm' "$#"
I copied perl6.bat to perl6, changed the initial path to moar to an MSYS-style path, and changed from cmd to sh quoting and arugment conventions.
Example run, from cmd:
C:\Users\cxw>perl6 -v
This is Rakudo Star version 2019.03.1 built on MoarVM version 2019.03
implementing Perl 6.d.
From the shell opened by msys2_shell.cmd:
$ uname -a

$ export PATH="$PATH":~/bin
$ cat foo.p6
use v6;
(2+2).say;
$ perl6 foo.p6

For what it's worth, my Rakudo bin dir:
$ ls -l /c/rakudo/bin

I'm following this guide so that I can run websites on a local server using Apache on OS-X El Capitan. I'm trying to edit my httpd-userdir.conf file but when I try to save it gives me the error:
Error writing httpd-userdir.conf: Permission denied
Terminal shows that the permissions for my httpd-userdir.conf file is -rw-r--r-- , so I don't understand why I wouldn't be allowed to write?

#erapert was correct, I just had to do sudo vi /etc/apache2/extra/httpd-userdir.conf and that allowed me to edit the file.
We have this strange problem with assets for our Rails 4.2.0 app. The CSS is fine in development and live compilation on production (config.assets.compile = true). But there is no CSS after assets precompile on production server:
RAILS_ENV=production bundle exec rake assets:clean assets:precompile RAILS_RELATIVE_URL_ROOT=/mysuburi
There is no error in precompile and here are the files under public/assets:

application-xxx.css and manifest-xxx.json are there. In Gemfile, the version of sprockets and tilt are set to:

We tried clean cache with assets:clean a few times with no avail. There are only a few values we can change for the assets. We have rolled back the version of sprockets to fix the problem in assets precompile. We have the default setup about assets location (public/assets) and application-xxx.csss file is there. What else could be wrong with CSS?
