command not found in zsh when it is there - linux

I just installed the android SDK and was trying to run the emulator when this happened:
:: ~ » echo $PATH
/usr/local/bin:/usr/bin:/bin:/usr/local/games:/usr/games:/home/neeraj/code/android/android-sdk-linux/tools:/home/neeraj/code/android/android-sdk-linux/platform-tools
:: ~ » whereis emulator
emulator: /home/neeraj/code/android/android-sdk-linux/tools/emulator
:: ~ » emulator
zsh: command not found: emulator
emulator seems to be in one of the $PATH directories, but zsh still says that it wasn't found. What could be the cause?

Try running rehash command, it helps in cases when some new software is installed. You can also try to run another shell instance (by executing zsh or logging out and in), this should also help.
Please also check file permissions to make sure you can read and execute that file.

Solved it. The problem was that emulator was a 32-bit ELF binary, and I didn't have the 32-bit runtime libraries installed. I installed the packages libc6:i386, zlib1g:i386, libstdc++6:i386 and lib32z1 as suggested in this answer, and that worked.

Changing CAPACITOR_ANDROID_STUDIO_PATH in Arch Linux

I'm trying to set up my development environment for CapacitorJS on Arch Linux.
I followed the documentation and added
CAPACITOR_ANDROID_STUDIO_PATH=/usr/bin/android-studio
to my systems environment variables (not the project) but I'm still getting the same error
[error] Unable to launch Android Studio. Is it installed?
Attempted to open Android Studio at:
/usr/local/android-studio/bin/studio.sh
You can configure this with the CAPACITOR_ANDROID_STUDIO_PATH
environment variable.
Even though It's never pointed to /usr/local/android-studio/bin/studio.sh
I ran whereis android-studio and got android-studio: /usr/bin/android-studio, so I thought that would be the correct path, but every time I run npx cap open android it says it's trying it launch from the same path and never changes
It depends how you've installed it, for example Toolbox installs it inside the user's home directory.
nano ~/.bashrc
export CAPACITOR_ANDROID_STUDIO_PATH=~/.local/share/JetBrains/Toolbox/apps/AndroidStudio/ch-0/202.7486908/bin/studio.sh
locate studio.sh might be able to find it, too.

sdkman on cygwin can't install

I'm setting up a new machine and installing sdkman on Cygwin to install Java. I had this exact setup working on my previous machine, also Win 10.
Installed Cygwin, and required for sdkman, installed zip and unzip packages. Now I'm getting the following error:
$ sdk i java 11.0.3-zulu
Downloading: java 11.0.3-zulu
In progress...
Warning: Failed to create the file
Warning: /home/whyph/.sdkman/tmp/D2txrZkztdcZKSIltTtxclUhHkzF9yIf.bin: No such
Warning: file or directory
curl: (23) Failed writing body (0 != 14095)
mv: cannot stat '/home/whyph/.sdkman/tmp/D2txrZkztdcZKSIltTtxclUhHkzF9yIf.bin': No such file or directory
Tried disabling Windows firewall and running Cygwin as administrator, neither changed the error. Worked out of the box on my last machine, but can't figure out what might be different.
I discovered the problem - wrong curl. Turns out, Windows 10 now comes with curl and it's on your path. I assumed it was one of the base packages of Cygwin, but it is not, and the Windows version is not compatible with SDKMAN, even though it worked to install it. Fix:
Remove SDKMAN per https://sdkman.io/install Uninstallation section
Close Cygwin shells
Rerun Cygwin setup and insure the curl, zip, unzip, and tar packages
are installed (check installation instructions in case more
dependencies are added since this writing)
Install SDKMAN per instructions
Recently I had the very same problem, and the reason was very simple... I forgot to install cURL on my Cygwin. Hope it helps!
I had the same problem recently and I manage to make it work somehow.
In the sdkman source file, I modified the .sdkman/src/sdkman-install.sh line 150.
I replaced the "--output" of the line below by a classic redirection ">".
After I just restarted cygwin and the command finally worked.
__sdkman_secure_curl_download "${download_url}" --output "${binary_input}"
Hope that helps !

Trying to use bash on Windows and got no installed distributions message

I am trying to use bash on Windows 10, but I'm getting this message when tried to run bash:
Windows Subsystem for Linux has no installed distributions.
Distributions can be installed by visiting the Windows Store:
https://aka.ms/wslstore Press any key to continue...
When I go to that url which opens the Windows Store app, there no sign of any Linux distribution there.
My windows version is(as in my right bottom corner of the screen):
Windows 10 Enterprise Insider Preview. Evaluation copy.Build
16215.rs_prerelease.170603-1840
I follow the instructions in this guide Installation Guide and also was watching this video Editing code and files on Windows Subsystem for Linux on Windows 10 from Scott Hanselman, but they didn't get the message of no installed distribution.
Any Help?
When the Windows Store opened, there was no Distro to choose, then I found this command lxrun /install and worked for me as well.
You will get something like this as an output:
C:\WINDOWS\system32>lxrun /install
Warning: lxrun.exe is only used to configure the legacy Windows Subsystem for Linux distribution.
Distributions can be installed by visiting the Microsoft Store:
https://aka.ms/wslstore
This will install Ubuntu on Windows, distributed by Canonical and licensed under its terms available here:

I'm getting a similar bug after trying to uninstall and reinstall.
For me I had to open a cmd prompt as administrator and run lxrun /install
I get this when I have recently rebooted. If I wait 5 minutes, the problem fixes itself !
The top answers written for this question are more than enough. I just had trouble following them because lxrun command has been depreceated, so I get the error
'lxrun' is not recognized as an internal or external command, operable
program or batch file.
when I try to run this command with cmd.
It has been replaced with wsl command. You can get more info on this issue here - https://github.com/MicrosoftDocs/WSL/issues/425
When you run wsl /install, there is a chance you may still get the error that you had earlier posted in your question. In that case, simply go to the link https://aka.ms/wslstore as you had gone earlier. If you don't see anything coming up, simply search for Ubuntu and install the same. (If you search with the term wsl though, you will get to see other Linux flavors too and then you can download any of your choice)
It seems that the link given in the command doesn't work. Here's the actual link to the microsoft store for Ubuntu.
https://www.microsoft.com/en-nz/store/p/ubuntu/9nblggh4msv6?rtc=1
You have to go to https://aka.ms/wslstore this link and download ubuntu on windows. After that you can use bash on windows.
If you have any problems with running lxrun /install (for example on ltsb Windows version) try manual mode.
First, go to the folder with downloaded .appx file and run following commands (change filename if needed):
Rename-Item ~/Ubuntu.appx ~/Ubuntu.zip
Expand-Archive ~/Ubuntu.zip ~/Ubuntu
After finishing cd into new folder and run ubuntu.exe file. That's it.
If you get this error after installing a distribution using the windows store, and WSL was working previously, you may need to make sure that the LxssManager service is running, since it often stops after a Windows update or a reboot.
Go to services.msc, and search for LxssManager and start it; if it is running already, restart it.
For everyone who is getting
'lxrun' is not recognized as an internal or external command,
operable program or batch file.
or
Windows Subsystem for Linux has no installed distributions.
Distributions can be installed by visiting the Microsoft Store:
https://aka.ms/wslstore
Open microsoft store, install 'Ubuntu' then open the app. This will install ubuntu and later you can use wsl command since lxrun is deprecated
Go to add or remove programs
Install Windows subsystem for Linux
Go to https://aka.ms/wslstore, which will take you to the Microsoft Store
Select and install a Linux distribution
lxrun /install
Works on a Administrator Command Prompt for Windows 10 Professional, Version 1803 Build 17134.165
This installs GNU/Linux by default whereas there is an option to select between:
Ubuntu
openSUSE Leap 42
SUSE Linux Enterprise
Debian GNU/Linux
Kali Linux
If the given link (https://aka.ms/wslstore) works, it openes the windows store for me with an error saying something is wrong on their side and to try again later.
It's actually easier to solve this problem that other solutions listed here. If you run wslconfig /l and if the output is:
Windows Subsystem for Linux Distributions:
Ubuntu (Default)
Just run wslconfig /s Ubuntu to set Ubuntu as default again. It should start working now.
Edit:
I've also found that if this problem occurs on a fresh boot, then you just wait for a few minutes (10 minutes max) and this error automatically disappears.
Edit 2:
I've also found that this error is sometimes also due to the corresponding service not running. Run CMD as administrator and run
net start LxssManager
For running bash on windows ubuntu is required to be installed.
As you've already added bash from programs and features, now you need to install Ubuntu. Contrary to what is seen in most of the installation guides on web, it does not gets installed by running 'bash.exe'.
You can simply go to Microsoft store in search for 'Bash' or 'Ubuntu'and install Ubuntu 18 LTS from there.
After installation you'll be able to use the terminal and all its commands.
Run the bash command in git bash windows. It worked !!
As of 2022, New Linux distributions are available for Windows 10 as well as Windows 11 like Kali Linux and Ubuntu. Both available from Microsoft Store. Someone watching this question now can visit Microsoft Store to Download them..
I had this same issue. But when you go to the windows store you can search for ubuntu and then install the ubuntu app and it works. I think most of the tutorials on the net are from the beta version and have afterwards never been updated.
https://insights.ubuntu.com/2017/07/11/windows-10-loves-ubuntu-loveislove/
Note: This is also old. You do not need to be on the insider builds. I'm not and it worked.
The only thing that worked for me is described here https://learn.microsoft.com/en-us/windows/wsl/install-manual#downloading-distros
https://aka.ms/wsl-ubuntu-1804
manually install it or run Add-AppxPackage.\.appx from PowerShell
The link to the store appears to have a region lock in it, resulting in errors for many visitors.
However there are different Ubuntu distributions to be downloaded. See image below, image is however in Dutch but it will show results.
So pick a version you desire and it will result in a working bash.
The actual answer to the question query is: The user exists with Ubuntu already installed. But WSL command does not find anything in CMD.exe "Command Line" "System does not find distribution."
You need to start the below WSL command from Windows Start Menu. And then the old Linux System will show up on WSL in the command line as found.
If this doesn't work for you? Just start up PowerShell with Administrator and:
WSL --help
WSL "only this command, will start the Linux default distro selected"
You can then start up using this command with CMD.exe Administrator in Windows:
lxrunoffline l "This will now list all your distros"
With an option to remove old distros copied to Windows folders are with perhaps Ubuntu18.04 such way that you will have to use Linux to remove older folders, do not try to copy or edit files in a distro with Windows Apps. You risk integrity problems as well as many errors followed by huge processing time. Use folder /mnt to find your drive with Linux and use commands there to further finish your work as perhaps copying the home directory into a new distro.
My solution to move "not copy" my distro then was: "to give space for C:"
lxrunoffline m -n Ubuntu-18.04 -d d:\wslinstalled\Ubuntu-18.04 "remember folder names"
"Remember folder name such as Ubuntu-18.04 for a specific movement. Unless you will overwrite everything on that folder name with also the lxrunoffline files and you risk losing older copies if you use one folder name. You might end up with a strange name to your project if you just use one directory."
Lxrunoffline has several other commands if you need help just run:
lxrunoffline
like beginner_ said in his answer you need to go to the store and look for the distros you want to install.
Please see the following link to understand what has changed and what you can excpect or what distros you can look for(the list is outdated so just try to find an updated list or just try your luck).
I am running on my machine without the developer mode Ubuntu, OpenSuse and Kali.
Access to Microsoft Store is blocked by my company. For me following worked in PowerShell (admin) -
lxrun /install
Go to cmd, and then run the following command:
lxrun /install
Typing lxrun /install in elevated command prompt works....
The solution to the error "WSL 2 installation is incomplete",
Execute the following steps:
wsl --install -d Ubuntu ## lxrun is no more, its now replaced with wsl,
enter image description here
wsl

can't run stipdet in open cv

I 'm trying to run some precompiled code (source code is not available) on Ubuntu, which requires openCV to be installed. I installed the latest version of openCV (from the SVN) yesterday, and installed it according to the debian install guide on the openCV website (cmake -> make -> sudo make install) and everything seemed to go fine.
I tried to run stipdet program but this gives me following error.
bash: ./stipdet: cannot execute binary file
Please can anyone help me with this error?
What does:
file $(which stipdet)
...say? I'm guessing it was built for a CPU you don't have.
You need to run chmod 755 ./stipdet to make stipdet executable.

Error installing Alfresco Community 4.0.b - Unterminated Uqoted String

When trying to install Alfresco 4.0.b in text mode on Ubuntu 10.04, I get the error:
./alfresco-community-4.0.b-installer-linux-x64.bin: 1: Syntax error: Unterminated quoted string
Is this related to the installer or Ubuntu? Some help to get it running?
Either corruption, or you are working on 32bit Operating System, use the command : uname -m to know this, if it gives something other than : x86_64 then you are not using a compatible version of UBUNTU, you have either to install a 64bit release of UBUNTU or choose the hard coded installation of Alfresco since the 4th version doesn't have a 32bit Alfresco installer.
Had the same issue but resolved it by making sure the .bin was executable by:
chmod 777 <filename>
You also need to run it as root and have './' before the filename:
$ ./alfresco-community-4.0.b-installer-linux-x64.bin
I used sh as I'm used to running shell/bash scripts. I think that's why it came up with the "unquoted string' error.
Could also have been that I used chmod +a instead of chmod 777.
