FWIW: I've tried modifying buildconf/default.ini adding xml = expat and it builds.

[iKeepWalking]

I've got the same problem :(

+1 @unbit Please check this question

[xrmx]

People, github added a way to add your reaction to the original submission so you can avoid annoying +1 . Please use them.

[BambiHaber]

Same here, tried to add

xml = expat

and it does not build

[ilubnon]

Hi Guys

In this way, it worked for me...

brew unlink libxml2
brew uninstall libxml2

then

brew install --with-python libxml2
brew link libxmls2 --force

pip install uwsgi

Possibly it might work just running the command:

brew install --with-python libxml2

[BambiHaber]

@ilubnon note that you have a type-o in the link line (libxmls2 instead of libxml2), but anyway it seems unrelated. I think this is having something to do with the fact of running a new XCode with OSX 10.11, which does not have to seem to have this /usr/lib/system/libsystem_symptoms.dylib file.

[smason]

seems unrelated, but works for me as well (didn't previously have libxml2) but installing it first allows uwsgi to build as well

[svetlyak40wt]

Tried right now – does not work:

I was able to successfully uninstall and reinstall libxml2, but I'm still unable to install uwsgi. I'm on Python 3.6.0.

[smason]

@svetlyak40wt that appears to be a problem with your homebrew formula, I get a slight different url appearing in my copy which is found. try again after a brew update

@AlJohri difficult to diagnose from what you have said. maybe it's not finding your homebrew libraries, try with:

LDFLAGS=-L/usr/local/lib pip install uwsgi

(assuming you're using a bourne shell and have homebrew in the standard place)

[subokita]

Going thru stack overflow, this works for me

sudo /usr/bin/sed -i.backup -E -e 's@/usr/lib/system/libsystem_symptoms.dylib(, )?@@' \
$(grep -ril /usr/lib/system/libsystem_symptoms.dylib \
/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.12.sdk/usr/lib)

Some people are saying that it's due to invalid references in Xcode, I have no idea.

[Dahie]

I don't have a solution, just some words regarding the general problem I had. I was working on OSX 10.11 (El Capitan) and already installed XCode 8. However for El Capitan XCode 8 does not ship with command-line tools and looks like support is not comming. My solution was to upgrade to OSX 10.12 (Sierra), update XCode and then it works.

[vikrantrathore]

It works after brew upgrades to new packages.

[gsong]

@vikrantrathore Brew upgrades to what new packages? I keep my brew packages up to date regularly and uwsgi still doesn't compile in my OS X 10.11.6.

This issue shouldn't be closed.

[gicornachini]

Hi @gsong ,
I did what @ilubnon said, but almost work, so i tried this and worked:

brew update
brew unlink libxml2
brew uninstall libxml2

then

brew install --with-python libxml2
brew link libxml2 --force

pip install uwsgi

My OS X is 10.11.6 too!

[dpatz]

Also make sure you are NOT in a virtualenv when you are running the brew commands

[yuxiaoxi]

@ilubnon i did what you said,there is always output "Error: Permission denied @ dir_s_rmdir - /usr/local/Cellar/libxml2/2.9.5" when i did brew uninstall libxml2 commond.Can you help me how to fix this.

[yuxiaoxi]

@ilubnon brew uninstall libxml2 cann't did,should rm this file by yourself

[00o0o]

export LDFLAGS="-L/Library/Developer/CommandLineTools/SDKs/MacOSX.sdk/usr/lib/system"

[unbit]

FYI on OSX the default xml parser is now expat

[salmanulfarzy]

This issue could also be related to XCode 9 and brew no longer have with-python option for libxml2.

Follow steps above with the change

➜ brew reinstall libxml2
➜ brew link libxml2 --force

[nosratullah]

I don't know why there're so many ways!
For me uninstalling 'libxml2' and then installing 'uwsgi' worked.
brew uninstall libxml2
pip install uwsgi
brew install libxml2
After installing 'libxml2' don't forget to link it!
