When building Chromium or libwebrtc with gn on macOS (Catalina 10.15), I get errors from the Python build scripts about bytes and str. For example:
src [heads/master●] % gn gen out/ios_64 --args='target_os="ios" target_cpu="arm64"'
ERROR at //build/config/ios/ios_sdk.gni:109:21: Script returned non-zero exit code.

When I edit the offending Python script to print(sys.version), it shows that it is running Python 3, even though the scripts are supposed to running with the bundled virtual Python 2.7 environment defined in .vpython.
How do I configure gn to run these scripts with the appropriate Python version?
It seems exec_script is running these scripts with the machine Python version. gn help exec_script says:
The default script interpreter is Python ("python" on POSIX, "python.exe" or
"python.bat" on Windows). This can be configured by the script_executable
variable, see "gn help dotfile".
For me, python points to Python 3. So I had to add this line to the end of the .gn dotfile:
script_executable = "vpython"
Now the build uses the virtual Python defined in .vpython, which is Python 2.7.
(The vpython executable is provided by Chromium depot_tools, just like gn.)

If I install it this way, I get no errors:
brew install pyqt#5
But my VS Code shows up like this, and none of submodules work:
My program used to work just fine, but I had recently installed Python 3.10 and have since uninstalled it. Ever since the new Python install, I've had this issue. Not sure how to tackle this. Thank you!
I've asked this question a number of different ways in a number of different places; none of the suggested answers work for me.
The closest thing to an answer that I got to was this:
https://www.zhihu.com/question/437075754/answer/1993415429
If you're unable to read it, it suggests this:
Pre-work, install homebrew, python 3.9.
First enter in the terminal:
brew install pyqt5
echo 'export PATH="/opt/homebrew/opt/qt#5/bin:$PATH"' >> ~/.zshrc
echo 'export PATH="/opt/homebrew/opt/pyqt#5/5.15.4_1/bin:$PATH"' >> ~/.zshrc
source ~/.zshrc
Then, copy all the contents of
/opt/homebrew/Cellar/pyqt#5/5.15.4_1/lib/python3.9/site-packages to
lib/python3.9/site-packages folder. If your homebrew installation
address and python installation address are not the default, you need
to modify these two addresses.
Finally, try it in python
import PyQt5
But this didn't work for me, either.
In the end, I ended up just installing PyQt6:
pip install PyQt6
The install completed without any errors. Now I am working on updating my code. Hopefully this will be useful for someone else coming here from an angry Google search. Code on, my friends.
I had the issue as yours. I solve with the following command.
pip3 install pyqt5
my install setup is
1.brew install qt
2.brew install libxml2
reference by TheCrazySwede answer ↓↓↓
3.brew install pyqt5
enter image description here
4.brew cleanup pyqt#5
5.echo 'export PATH="/opt/homebrew/opt/qt#5/bin:$PATH"' >> ~/.zshrc
6.echo 'export PATH="/opt/homebrew/opt/pyqt#5/5.15.4_1/bin:$PATH"' >> ~/.zshrc
7.source ~/.zshrc
8.pip3 install pyqt5-sip

I am getting this error while running the sample file given with TensorFlow, in the imagenet model,
File "classify_image.py", line 154, in run_inference_on_image
if not tf.gfile.Exists(image):
AttributeError: 'module' object has no attribute 'gfile'
I have tried installing using both, from pip as well as source, on virtualserver as well, still I get this error.
There are two ways to go about solving this problem:
Option 1
This is an expansion on Yaroslav's comment above, and is easier than option 2.
Modify classify_image.py as follows:
Replace all instances of tf.gfile.Exists to os.path.exists, and
replace all instances of tf.gfile.GFile and tf.gfile.FastGFile to open
Then run the modified classify_image.py, and it should work.
Option 2
Update tensorflow to the latest version that includes gfile as described here
However, after you do that, you might encounter the following error when you try to run classify_image.py:
$ python classify_image.py

To fix this, you can change a line in the source code as described here and then recompile tensorflow on your machine.
Option 2 might be a bit of work, especially if you're on a Mac.
The following steps helped me resolve the issue
update tensorflow as described here https://www.tensorflow.org/versions/r0.7/get_started/os_setup.html
2.For me this resulted in protobuf error. To resolve I ran
$sudo pip uninstall protobuf
$sudo pip install --upgrade

EDIT : Ok I don't know what was going on but I restarted for the beginning the building and this seems to work. I don't have any gcc. When i type gcc -v, one answer me that I have clang instead of it ... When i makeit at the first time, the console asked me to rename my directory opt/local because of homebrew. Is think that is what didn't work at the first time. I rename it opt/local during the compilation of sage ...
Probably this is due to a Python build (Sage's Python, that is) that didn't successfully build this module; see this sage-release thread. In principle http://trac.sagemath.org/ticket/17174 should have fixed it (see http://trac.sagemath.org/ticket/17169) but perhaps you are using a non-Sage gcc, such as homebrew? In that event you'll need to either make that change somewhere or perhaps to just use Sage's gcc, which you do with SAGE_INSTALL_GCC=yes (though that will take longer, of course). Good luck!
I have been trying for months to get numpy installed for Python 3 but despite copious amounts of Googling and even posting to the numpy mailing list I am still no closer to a solution.
I have managed to get it installed via MacPorts but unfortunately there doesn't appear to be a port of MatPlotLib for Python 3 which is the main reason I am trying to install numpy...so I am a bit stuck...
I keep getting the same error whilst trying to build from the setup.py file. I have included the terminal output below.
Thanks for any help you can offer,
Adam.

Well, I finally managed to get NumPy to install. Not sure it is the best method but it seems to work!
First of all i needed to install distribute:
curl http://python-distribute.org/distribute_setup.py | python3
Then I installed pip:
curl https://raw.github.com/pypa/pip/master/contrib/get-pip.py | python3
After that I had to get pip on to my system path (again there are probably better ways):
Open Terminal
Type the following (single line):
sudo ln -s /Library/Frameworks/Python.framework/Versions/3.2/bin/pip /usr/local/bin
With distribute and pip installed I then installed Nose, which NumPy needs for testing or something:
Again, in Terminal type the following:
pip install nose
Now I needed to make sure I had the latest version of Xcode:
From the AppStore install the latest version of Xcode
If you still have a /Developer folder then rename it Developer-old (not sure whether this will cause problems for me later or not)
Open Terminal and create a symlink to the AppStore version of Xcode (single line):
sudo ln -s /Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer /Developer
With all of that out of the way time to install NumPy:
Download the NumPy source from: http://sourceforge.net/projects/numpy/files/NumPy/1.6.2rc1/
Unarchive the file
Open Terminal again:
cd into the directory created by unarchiving the file e.g.
cd /Users/username/Downloads/numpy-1.6.2rc1
Type into the Terminal the following to change the complier used to build NumPy:
export CC=clang
export CXX=clang
export FFLAGS=-ff2c
export LDSHARED='clang -bundle -undefined dynamic_lookup -arch i386 -arch x86_64 -isysroot /Developer/SDKs/MacOSX10.6.sdk -g' (this is a single line)
python3 setup.py build (this may take a while)
python3 setup.py install
Okay, assuming there were no errors NumPy should be installed. Time to test it out:
Open IDLE
In the Python Shell type:
import numpy
numpy.test('full')
This will test NumPy the final result I received with Python 3.2.3 was:
<nose.result.TextTestResult run=3192 errors=0 failures=1>
So the NumPy installation passes all except one test, which seems pretty good. I haven't had a chance to see if works properly yet as I am still struggling to get matplotlib installed...
Hope these instructions are useful to somebody!
Adam.
I'm using Python 3.3 and OS X 10.7, and I installed numpy using a much easier method than above. I'm posting here in case it can help someone.
Follow these steps:
Download the zip file from numpy on github, and unpack it wherever you want.
Open a terminal and cd to the directory
enter the command python3 setup.py build --fcompiler=gnu95 (requires gfortran. Enter gfortran -v to see if you've got it, I've got version 4.6.2)
enter python3 setup.py install
That's all it took for me. Running numpy.test('full') gives me some errors, however: http://pastebin.com/5XF0qAe5
I don't know what kind of errors I'm going to experience yet.
The above answer worked great for me, except that you mentioned this was for OS X 10.7 (same here) so my build command did complain about the line:
export LDSHARED='clang -bundle -undefined dynamic_lookup -arch i386
-arch x86_64 -isysroot /Developer/SDKs/MacOSX10.6.sdk -g' (this is a single line)
So, I just changed that to 10.7 and it worked fine. Apparently, for OS X 10.7, the /Developer/SDKs/ directory contains MacOSX10.7.sdk and MacOSX10.8.sdk. Thanks for the great answer!
I've come back to this answer a number of times, if you're using 10.8, you need to do a few things to get this to work (but I don't think you need the LDSHARED part).
Install XCode from Apple as well as the command line tools (this gets you the compilers you need).
set environment variables to point to clang and use easy_install (NOT distribute) to install, this line will work:
CC=clang CXX=clang FFLAGS=-ff2c easy_install numpy
Do not try to install other packages at the same time. The numpy install may exit claiming an error, but often it manages to install itself anyways (for example, if you try to install in a virtualenv, this may happen).
for me i installed python3 from their website and then to install numpy,
pip3 install numpy
it works!
