I'm trying to install gatsby-plugin-sass and I'm getting the following error:
xcode-select: error: tool 'xcodebuild' requires Xcode, but active developer directory '/Library/Developer/CommandLineTools' is a command line tools instance
I can't find anything that tells me how to get past this error and I absolutely do not want to download the memory hog known as Xcode.
xcode-select is already installed, verified when I run xcode-select -install. And I vaguely remember installing it a long time ago to get Sass to work (and Sass still works on my system.)
Is there a way to satisfy this error that doesn't involve installing XCode? I really don't want to waste the gigabytes on it.
It appears to actually be an issue with node-gyp yet none of the fixes on their issues page seem to work for me.

I have a problem that I'm not sure how to solve, I'm trying to use expo-mail-composer but when trying it on the emulator I get the following error. The problem is solved once I uninstall the package but I need it to send some files to a specific email,Currently only what is necessary for android only
From what I saw, the problem is with the package itself, because if I uninstall it, everything works correctly, I tried different versions and looked in various places for the error but I have no idea, I tried installing the packages that were required in the error, but even so it didn't work
I have the following problem:
I am on Ubuntu 20.04 and I am trying to set up GNUstep which is required for certain source binaries I want to build
(for the sake of completion, the program I want to build is called Advanced Rendering Toollḱit, information can be found here: https://cgg.mff.cuni.cz/ART/).
When building with the clang-9 compiler, after invoking the make command, I receive this error message:
fatal error: 'objc/objc.h' file not found
I should mention that I am still fairly new to Linux in general. What I did was installing GNUstep via
sudo apt-get install gnustep gnustep-devel
as advised on the website (http://wiki.gnustep.org/index.php/GNUstep_under_Ubuntu_Linux). It resulted in receiving the mentioned error.
/usr/include/GNUstep/Foundation/Foundation.h:31:9: fatal error: 'objc/objc.h' file not found
The next thing I tried was to download the provided configuration scripts from the same webpage and execute them. When I did, I received the following feedback:
checking whether objc really works... no. I don't seem to be able to use your Objective-C compiler to produce
working binaries! Please check your Objective-C compiler installation.
If you are using gcc-3.x make sure that your compiler's libgcc_s and libobjc
can be found by the dynamic linker - usually that requires you to play
with LD_LIBRARY_PATH or /etc/ld.so.conf.
Please refer to your compiler installation instructions for more help.
configure: error: The Objective-C compiler does not work or is not installed properly.
Maybe I am getting something wrong, however, my whole intention of installing GNUstep is to make Objective-C programming possible on a non-Apple machine. Therefore I do not understand why it is complaining about a non-working Objective-C compiler (by the way, I end up with the same result when using gcc and g++ as compilers).
I did do some research and I came across some StackOverflow posts, suggesting me to install libobjc2, but I suspect this to be depreciated with Ubuntu 20.04.
I honestly don't know what's wrong and I highly appreciate a little push in the right direction! Many thanks in advance for helping me!
Although I cannot tell what exactly the bug was in my case, I got some external help and together we came up with a solution that worked for me.
For debugging purposes, we created a test user account in my Ubuntu environment and repeated the whole process. It worked flawlessly.
We concluded that something must have been wrong locally with regard to my user account. I am sure there was something wrong with my environment variables, although I failed to clearly identify the bug (I am a Linux beginner). I chose the easy way out, backed up important files, deleted and re-created my root user account and then it worked. I hope, this may help any other who has the same problem.
#skaak, thank you for your help and suggestions!
As people are pointing, if you want to use clang to compile objective C programs in Ubuntu you have to install libobjc2 (mainstream project here) but it's currently not packaged in Ubuntu. It's possible that there was a package with the same or similar name, as you found out, but that was a different thing. This manual installation worked for me:
wget https://github.com/gnustep/libobjc2/archive/v2.0.tar.gz
tar xvzf v2.0.tar.gz
cd libobjc2-2.0
mkdir build
cd build
export CC=`which clang`
export CXX=`which clang++`
cmake ..
make
sudo make install
I'm trying to install some fonts in Arch Linux (using yay font). The installation is fine, no problem at all. But, after restarting my computer, those installed fonts are gone. I tried to install them again, and restarted. The fonts are always gone.
I also notice that I have to update a lot of packages every morning (using yay). But they are not always the same packages, thus I've thought they may just update so frequently.
I've just started using Arch Linux 2 months ago, and I struggled a lot to install it. Therefore I think I might still leave a lot of errors and mistakes. I need some help please, thank you very much.
The problem is solved today somehow. Apparently, there were a lot of errors and warnings when I used pacman -Syu, and never read all of them. It has gone like that until now. Then, I got a conflict when updating packages, searched on Google, solved it, rebuilt all packages, and this problem is somehow gone as well.
In MonoDevelop when compiling and running an app developed for Android against the simulator, the app compiles then crashes immediately in the simulator with the following application output...
E/mono ( 225): The assembly mscorlib.dll was not found or could not be loaded.
E/mono ( 225): It should have been installed in the `/home/jon/Development/xamarin/mono/BUILD/armeabi/install/lib/mono/2.0/mscorlib.dll' directory.
Keep in mind that I'm not Jon so I don't even know where it's getting the /home/jon path configuration. Though I have found that path in other similar but ultimately unrelated searches on the internet so I imagine it's a path on some other devs machine.
mscorlib.dll is indeed on my machine. located here...
/Developer/MonoTouch/usr/lib/mono/2.1/
and here...
/Developer/MonoAndroid/usr/lib/mono/2.1/
I've tried targetting various Android SDK environments (currently 2.3 and the simulator is currently running under the 2.3 SDK environment as well).
I'm on Mac OSx 10.7.2. Using the latest version of MonoDevelop, Mono and Mono for Android. I've also got the latest MonoTouch installed as well and iPhone apps compile fine if that's worth anything.
The closest thing I can find to a hint at the issue is here...

I've tried reinstalling Mono and Mono for Android but admittedly have not tried uninstalling in entirely before a reinstall. I've searched within files for the /home/jon path thinking that it must be a configuration somewhere but haven't been able to find it anywhere.
I found this... Mono return error: mono mscorlib.dll was not found
Along with a few other things that were sort of in the same vein, but ultimately nothing that seems to be a fix.
Any ideas?
Update: From the suggestions in jonp's answer below it indeed seems like the Mono.Android.DebugRuntime package is not installed. So far I've tried a couple of MonoAndroid reinstalls and have tried removing MonoAndroid entirely beforehand. I'm trying to figure out if there is a way to add the package manually, but I'm so new to this.
Another update: Not sure why I didn't try this already, but I created a HelloWorld MonoAndroid app and it works fine. The compilation took a while longer too for that one and I could see if was setting up the required packages, so there has to be an issue with the specific solution.
When you install a Debug build of your app on the device, three .apk files are installed:
Mono.Android.DebugRuntime, which contains libmonosgen-2.0.so, mscorlib.dll, etc.
Mono.Android.Plaltform.ApiLevel_N, which contains Mono.Android.dll for API level N.
Your application.
My guess is that the Mono.Android.DebugRuntime package has not been installed. To check this, run:
adb shell pm list packages | grep Mono.Android
I'm going to guess that it's missing. :-)
Next, why is it missing? When you Run the app within MonoDevelop, all required packages are checked for and installed. It seems rather odd that it wouldn't be. Is your device low on disk space?
adb shell df /data
How are you launching the emulator? If you're launching within MonoDevelop, there should be enough free space to install all of the above packages. However, if you launch it yourself, the default /data size is 64MB, which isn't enough to support a Debug build environment. Please launch the simulator from MonoDevelop and re-Run your app, or launch the emulator so that it has enough free space:
emulator -partition-size 512 -avd YOUR_AVD_NAME
I've been tearing my hair out over this, and Google hasn't yielded much so my problem must be caused by my own specific brand of stupidity.
Basically, having installed Xcode 4 I removed the /Developer-old folder (properly, can't remember the command but I used the uninstall script rather than sticking it in the trash).
Xcode builds projects fine, and the latest version of all the Objective-C frameworks seem to live in /System/Library/Frameworks, but when I compile something (which built fine in the Xcode 3 days) clang complains that it can't find any headers, e.g:
fatal error: 'Cocoa/Cocoa.h' file not found
I've tried forcing the framework search path with -F to no avail- is there a common underlying issue or have I just screwed my machine?
Reinstall the developer tools. It will take a lot less time than tracking down whatever you broke.
