I am cleaning up my MacBook and would like to know the basic /usr/ filesystem structure so that I can delete components that are not essential in running my system, in order to have an idea about what not to touch. I got curious about this after cleaning out the /usr/local/ directory to reinstall Homebrew and to save storage on my laptop.
So the following is what I see at /usr/ with my Terminal:
lrwxr-xr-x 1 root wheel 8 Dec 25 2018 X11 -> /opt/X11
lrwxr-xr-x 1 root wheel 8 Dec 25 2018 X11R6 -> /opt/X11
drwxr-xr-x 971 root wheel 31072 May 22 05:52 bin
drwxr-xr-x 265 root wheel 8480 Jun 5 23:39 include
drwxr-xr-x 322 root wheel 10304 Jun 5 23:39 lib
drwxr-xr-x 250 root wheel 8000 May 22 05:52 libexec
drwxr-xr-x 15 root wheel 480 Jul 14 07:09 local
drwxr-xr-x 239 root wheel 7648 May 22 05:52 sbin
drwxr-xr-x 46 root wheel 1472 Oct 19 2018 share
drwxr-xr-x 5 root wheel 160 Sep 21 2018 standalone
Is there anything not needed that I can prune in this directory? Or should I leave things as they are?
I think it would be better to leave it as it is.
for example: the bin include lib folder contains the installed applications and compiled libraries on your Mac, so you could remove something from it and then once of the dependencies will be upset.
I believe it's better to not change any thing inside the usr folder

I just changed my dev machine from a windows box to a macbook pro (m1 chip). I need to be able to build / compile / debug a dotnet 5.0 project.
I'm assuming I can download multiple versions of the SDK and runtimes on my mac ... like the net6.0 for arm64 bit and net5.0 x64. (doesn't seem to be arm64 for .net 5.0 per the docs)
I've installed both SDKS using these two dotnet installers you see below:

I didn't get any errors during either install. But at this point, when I check the list of dotnet sdks, I only see the 6.0 version:

Can someone point me in the right direction / tell me where I'm going wrong?
Just to be sure that the 6.0 install is working, I spun up a new project like this:
dotnet new webapp
and I was able to compile.
Thanks.

Per the comments just going to upgrade the project to 6.0.
Error when installing
Error when uninstalling
Currently trying to help a fellow student install HomeBrew but getting this error every time we are trying to download HomeBrew. Tried various scripts for uninstalling as well but also getting errors.
Any solutions?

Did the install accidentally a file? Does Yosemite just ship with a busted Ruby header file set?
What's the best way to fix this? Can I just unpack the source code in there to get the right headers?
One note on this: I ran into this problem after upgrading to "OS X El Capitan". I installed the command line tools by running 'xcode-select --install'. After that, my ruby build environment started working again.
For those who already had Xcode installed from the Apple developers site, running xcode-select --install doesn't work, since it will say that Xcode is already installed (Xcode already comes with the CommandLineTools bundled).
In my case, I fixed it by downloading the corresponding CommandLineTools from the same place, executing it, then going to /Library/Developer/CommandLineTools/Packages/macOS_SDK_headers_for_macOS_10.14.pkg and executing it too.
cd /Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.11.sdk/System/Library/Frameworks/Ruby.framework/Versions/2.0/usr/include/ruby-2.0.0/ruby
sudo ln -s ../universal-darwin15/ruby/config.h ./config.h
updates Nicholas Tsipanov's answer from 2014-10-18.
I got the same error, but installed "Command Line Tools (OS X 10.10) for Xcode - Xcode 6.1" and installing worked fine after that.
If you use Homebrew, brew install ruby is a fast workaround (it gets you a brand new ruby installation distinct from the one from Xcode).
Try this:
cd /Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.9.sdk/System/Library/Frameworks/Ruby.framework/Versions/2.0/usr/include/ruby-2.0.0/ruby
sudo ln -s ../universal-darwin13/ruby/config.h ./config.h
Xcode got messed up in the upgrade somehow.
I opened Xcode (which I never do otherwise) and it complained about all sorts of missing components. So I let it go ahead and fix itself, and now all is well.
Props to CDub in the comments on OP for pointing to this as a potential source of weirdness.
I am running Mojave 10.14.6. The answer here fixed the subject issue for me: https://stackoverflow.com/a/58084238/284651
Solution:
sudo rm -rf /Library/Developer/CommandLineTools
xcode-select --install
sudo xcodebuild -license accept
open /Library/Developer/CommandLineTools/Packages/macOS_SDK_headers_for_macOS_10.14.pkg
Fixed by pointing to correct path for Xcode developer tools.

I've tried to configure my IntelliJ 13.1.5 + Ruby 6.5.2 plugin to run RSpec tests.
When I go to Run -> Edit Configurations and check the checkbox "Run the script in context of the bundle (bundle exec)" in Bundler tab, I get error "Run configuration error: No Gemfile found". See attached screenshot.
My Gemfile is definitely present in the root of working directory. Look for ls -la output below:

Question: how can I fix that error "Run configuration error: No Gemfile found" ?
I ran into the same issue today and after many hours I was able to fix it.
The environment where this issue occurred was: Ubuntu 14.04.1, IntelliJ 13.1.5, Test::Unit Test runner UI attached for framework, RubyMine plugin 6.0.0.20140123, rbenv and Ruby 2.0.0-p594
To resolve this "Run Configuration error: No Gemfile found", I had to:
Delete the Gemfile.lock located at the root of the project
From the shell command line, navigate to the project root folder and run "bundle install" so that Bundler started fetching gem metadata from https://rubygems.org/........
Go back to Intellij and reselect an SDK for the project at File -> Project Structure
Go to edit configuration, delete and recreated the rake configuration
I hope this would work for you... I also did other steps that I don't think they were necessary like restarting Intellij, reimporting the project, checking on and off the Test::Unit and the bundler option
Last, I want to share the steps that I had to do to reproduce this issue from scratch:
Imported a ruby project into Intellij
From the shell command, installed rbenv then installed ruby 2.0.0-p594
From Intellij, navigated to File -> Project Structure -> Project and set the SDK to rbenv 2.0.0-p594
From the shell command, installed bundler as follows: gem install bundler
Then back to Intellij were I navigated again to File -> Project Structure -> Project and noticed that the SDK was set back to , I set the SDK back to rbenv 2.0.0-p594
As soon as I hit ok, a popup showed up in IntellJ asking to install Ruby Plugin Gem Manager so I clicked on "install missing gem" link
After the installation was over, I navigated to Edit Configuration, switched to Bundler tab and as soon as I selected Run the script in the context of Bundler check box, I got the "Run Configuration error: No Gemfile found"
So I think that installing bundler late in the project configuration process caused this issue to surface
I have the exact same error, but different rubymine version on Windows and I use Rack configuration tempalte, here is my answer generally it will be the same concept: RubyMine somehow only looks for Gemfile in the "Settings/Project: projectname/Project Structure" so if you copy and paste the missing Gemfile into the Parent Project directory it will get picked up. However, I think Rubymine should also scan for subdirectories where Gemfile existing to include it, or probably rubymine has a way to override the default Gemfile by specify another Gemfile location - this i do not know.
Issue resolved for me.
I had faced the same problem in RubyMine 2018.3.5 version. And I found that my project structure was
Parent Folder
-> Project Folder
-> Vendor folder
-> Gemfile (etc.)
when I changed the structure to
-> Project Folder
-> Vendor folder
-> Gemfile (etc.)
Then there was no complain about "No Gemfile Found"
The basic checks which I think is necessary to debug in Rubymine are
Set the project structure as above
Verify jruby version and its gems(Preferences -> Languages & Frameworks -> Ruby SDK & Gems) My Jruby Version is 9.1.7.0
In Run/Debug Configuration -> Bundler set the checkbox Run the script in context of bundle (bundle exec)
above points are basic ones to begin with, you might need to install the missing gem or right version of gem after this configuration.
I use pip install as root. Everything works with CPython because it doesn't use the cffi backend. With PyPy I get the following error:
ImportError: PyZMQ CFFI backend couldn't find zeromq: [Errno 2] No such file or directory:

But, there is no __pycache__ directory.
By poking around the cffi Python files (in particular verifier.py) I found that it can't find the following cffi_g5368a726x67d4e236.pypy-20.so. I couldn't find it anywhere either. I guess it is not built for some reason, but I didn't see any errors during pip install.
Does anyone have any idea?
