I'm on OS X and I'm trying to get python3 working in sublime. I installed python3 via homebrew and I installed numpy for both python and python3 using pip. In order to be able to build python3 I added the following build file for sublime:
{
"path": "/usr/local/Cellar/python3/3.4.2_1/bin",
"cmd": ["python3", "-u", "$file"],
"env":{},
"file_regex": "^[ ]*File \"(...*?)\", line ([0-9]*)",
"selector": "source.python"
}
Finally I'm trying out the build system on the following test file:
#test.py
import numpy
def square(x):
return x * x
if __name__ == '__main__':
print("test: square(42) ==", square(42))
If I build this with the build system set to python (which uses the OS X default version of python 2.7.8) then I get the following (correct) output when I build in sublime:
('test: square(42) ==', 1764)
[Finished in 0.1s]
However, if I set my build system to build with python3 I get the following strange results when I build in sublime:
sh: sysctl: command not found
sh: grep: command not found
sh: sw_vers: command not found
sh: grep: command not found
test: square(42) == 1764
[Finished in 0.1s]
I still get the correct output but also get a bunch of command not found. What's even stranger, if I save this script and run it directly from the terminal using python test.py for python 2.7.8 or using python3 test.py for python 3 I get the correct output in the terminal. Additionally, if I remove import numpy from test.py I no longer get any of the command not found errors in my sublime output.
This problem seems to only show up in sublime using python3 with the above build file and only when I'm trying to import a library installed with pip. If I change the above import in test.py to sys then it will build in sublime without any error messages.
I think I have an answer for you.
Your path variable
"path": "/usr/local/Cellar/python3/3.4.2_1/bin",
needs to append to the existing $PATH. Simply replacing that line in your build file with
"path": "$PATH:/usr/local/Cellar/python3/3.4.2_1/bin",
fixed it for me.

So, I've installed the Octave Symbolic Package from here:
https://sourceforge.net/p/octave/symbolic/ci/master/tree/
In the Octave command window I typed:
pkg install -forge symbolic
After the install I ran a test (as shown in link above) by typing:
pkg load symbolic
syms x
However, I got an following error with syms x.
Symbolic pkg v2.8.0: Traceback (most recent call last):
File "<string>", line 1, in <module>
ImportError: No module named sympy

Next, I visited the following site to install SymPy (which says to install Anaconda).
https://docs.sympy.org/latest/install.html#anaconda
So, then I go to the following site and download the graphical installer for macOS (Python 2.7 version).
https://www.anaconda.com/distribution/#download-section
Then I tested from the macOS terminal to see if Anaconda is installed using this command
conda --version
which returns conda 4.7.11.
I also typed
conda list
which returns (among a long list). sympy 1.4 py27_0.
So, it appears that SymPy is installed (at least at the terminal).
Next, I go back to the command line of Octave and typed:
sympref diagnose
Here is the output:
Symbolic package diagnostics
============================
Python and SymPy are needed for most features of the Symbolic package.
The Python interpreter is currently: "python".
Computers may have more than one Python interpreter installed. If you
need to, you can select a different one using the PYTHON environment
variable (see "help sympref"). For example, to use Python 3, try
setenv PYTHON python3
sympref reset
Attempting to run python -c "print(\"Python says hello\")"
status = 0
output = Python says hello
Good, Python ran correctly.
Python version
--------------
Let's check what version of Python we are calling...
Attempting to run python -c "import sys; print(sys.version)"
status = 0
output = 2.7.15 (default, Feb 5 2019, 12:31:36)
[GCC 4.2.1 Compatible Apple LLVM 8.0.0 (clang-800.0.42.1)]
SymPy Python Library
--------------------
SymPy is a Python library used by Symbolic for almost all features.
Attempting to run python -c "import sympy; print(sympy.__version__)"
Traceback (most recent call last):
File "<string>", line 1, in <module>
ImportError: No module named sympy
status = 1
output =
Unfortunately status was non-zero: probably Python cannot import sympy.
* Is there an error message above?
* Do you have SymPy installed? If not, please try to install it and
try again.
* If you do have SymPy installed, maybe it's installed for a different
Python interpreter than the one we found? Please try "setenv" as
described above to change your python interpreter.
Octave doesn't have access to SymPy.
Any idea what I did wrong?
Try running these in octave...
setenv PYTHON /usr/local/anaconda3/bin/python
pkg load symbolic
/usr/local/anaconda3/bin was where all my anaconda bits were installed,
including a version of python. Yours may differ.
sympref diagnose then passes for me.
You will have to do this every time you start 'octave' before using the symbolic package, but it should be safe.
If I want to debug the setup.py file of my package packagename getting installed via "pip install packagename" , is there a way to do so? I have tried downloading the source, adding set_trace() in setup.py and run:

Although I can debug the source via: python setup.py build, the behavior that I want to debug is applicable when installed through pip.
Pip is a python program. You can see it's content with cat $(which pip). Then you can copy it to a new file in your project's directory. For example, here is how it looks like for me:
File mypip.py:
#!/usr/bin/env python3
# -*- coding: utf-8 -*-
import re
import sys
from pip._internal.cli.main import main
if __name__ == '__main__':
sys.argv[0] = re.sub(r'(-script\.pyw|\.exe)?$', '', sys.argv[0])
sys.exit(main())
Then you can add a breakpoint with pdb or use PyCharm as mentioned in the answer from Igor Yudnikov.
For reference, this is how it to looks like in my Pycharm
Oh! Just found a solution, its pretty easy. What is pip? It's a plain python file, which is I think somehow bound to run via python, and under the hood system makes something like
python pip install ...
so, at first we need to know where is pip
which pip
says
/Users/me/PycharmProjects/etlscripts/venv/bin/pip
So, we may go to Pycharm, create config like
then you'll be able to catch your exception. Cheers.
I followed the instructions in this link about Kivy installation "Using Homebrew with pip".
However, when I tried to run the code given below:
from kivy.app import App
from kivy.uix.button import Button
class TestApp(App):
def build(self):
return Button(text='Hello World')
TestApp().run()
It gave me an error:
bash: kivy: command not found
if you installed kivy with pip, you don't need a kivy command, you can use python directly.
python main.py
Because I created a virtual environment to isolate all the things that needs to be installed like kivy, and I installed cython and kivy first before the homebrew, it caused the problem. Even if I use:
python main.py
instead of
kivy main.py
What I did to solve it are the following:
1. Created a new virtual environment
2. Followed the instruction in kivy in right order: (1) homebrew, (2) Cython, then (3) Kivy.
3. Used "python" command instead of "kivy" command because I installed it using pip (refer to the commenr above). For example:
python name_of_your_file.py
Kivy documentation must be confusing that's why.

It appears that installs are different on Anaconda.
Per this page the proper installation procedure is:
conda install -c conda-forge gitpython=2.1.1
Installation on Python 2 was straightforward.
Update: I had to add the following to sys.path for Python 3:
C:\Anaconda3\pkgs\gitdb-0.6.4-py35_1\Lib\site-packages
I have no idea why python 2 installs in site-packages as expected, while python 3 installs in the path shown above.
Update2: I also had to update the Windows PATH variable (not just sys.path) to point to the directory containing git.exe.
I'm trying to use cx_freeze 4.3.3 on a MacOS running 10.9.2 on a very simple PyQt5 script with Python 3.3.
No errors are returned and the .app is output. However when running the .app from terminal I obtain the error:
LSOpenURLsWithRole() failed with error -10810
which according to Apple's documentation is "Unknown Error".
The very simple code I try to run (PyQt5app.py) is:
import sys
from PyQt5.QtWidgets import QApplication, QDialog
app = QApplication(sys.argv)
form = QDialog()
form.show()
app.exec_()
The file setup.py is:
import sys
from cx_Freeze import setup, Executable
base = None
if sys.platform == 'win32':
base = 'Win32GUI'
options = {
'build_exe': {
'excludes': ['Tkinter'] # Sometimes a little finetuning is needed
}
}
executables = [
Executable('PyQt5app.py', base=base)
]
setup(name='PyQt5app',
version='0.1',
description='Sample PyQt5 GUI',
executables=executables,
options=options
)
and when running I call:
sudo python cx_freeze bdist_mac
obtaining this log : http://pastebin.com/VBxyyBRn
with app returning error above.
So, reading around I see it might be a problem related to including qt files in the app (or at least this was the issue on PyQt4) so I try specifying the qt-menu-nib directory:
sudo python setup.py bdist_mac --qt-menu-nib=/Users/franco/Qt5.2.1/5.2.1/clang_64/plugins/platforms/
obtaining this log: http://pastebin.com/TpRdrSmT
and the same not working error.
If I run the app from PyQt5app.app/Contents/MacOS/PyQt5app I get a lot of bootstrap errors:

Needless to say the script works fine when launching from terminal:
python PyQt5app.py
I most certainly am doing something wrong, so please, can anybody help me?
So, after long fighting here is the issue: libzmq .
I installed libzmq and specified the --qt-menu-nib option and the simple example above runs in both:
sudo python setup.py build
and
sudo python setup.py bdist_mac
Step by step instructions:
I used mac ports for most of my python33 packages so I sticked to it for the rest.
Libzmq is not available on macports but its dependencies are.
So:
1) install libtool, autoconf, automake:
sudo port install libtool
sudo port install autoconf
sudo port install automake
2) grab the latest version of libzmq from https://github.com/zeromq/libzmq ( I downloaded the ZIP for sake of order ) and unzip/navigate to the folder
/libzmq-master
now the instructions provided in the INSTALL document in the folder are pretty clear, if you installed all the dependencies then you will be fine.
run:
sudo ./autogen.sh
sudo ./configure
sudo make
sudo make install
3) download the latest cx_freeze from https://bitbucket.org/anthony_tuininga/cx_freeze/downloads then unzip/untar navigate to folder and run:
sudo python setup.py build
sudo python setup.py install
now when compiling code for MacOSX that uses Python3.3 and PyQt5 you can run:
sudo python setup.py build
then navigate in the build folder and run the program as:
./nameoftheprogram
once you made sure this work then build the app or dmg (as you prefer) with:
sudo python setup.py bdist_mac --qt-menu-nib=/Users/username/Qt5.2.1/5.2.1/clang_64/plugins/platforms/
where the path is the path to your Qt5 installation. If I don't use the --qt-menu-nib option the app crashes on startup whereas the build works fine.
Hope this will help someone in the future.
I got the same error and recompiling with the latest version of ZMQ (4.0.4) did not solve the issue.
However, by looking in the messages of the /Applications/Utilities/Console.app program, I could see that an extra command line option was given to my Python program. This command line option always started with -psn_0_ followed by a number. Apparently psn stands for Process Serial Number (see: http://hintsforums.macworld.com/showthread.php?t=11978).
My program uses the argparse package to parse the command line arguments and exited with an error because it didn't recognized the -psn option. I now filter it out before parsing with argparse and this solved my problem.
