When I want to install the package wxPython-2.8.7.1.spkg from here
in the terminal of Sage it gives me a syntax error. What i write in Sage terminal and the result are as follow:
sage: sage -i wxPython-2.8.7.1.spkg
------------------------------------------------------------
File "<ipython console>", line 1
sage -i wxPython-RealNumber('2.8').gen(7).1.spkg
^
SyntaxError: invalid syntax
I also use the direct address of the package but the result was the same:
sage: sage -i http://www.sagemath.org/packages/experimental/wxPython-2.8.7.1.s>
------------------------------------------------------------
File "<ipython console>", line 1
sage -i http://www.sagemath.org/packages/experimental/wxPython-RealNumber('2.8').gen(7).1.spkg
^
SyntaxError: invalid syntax
I also downloaded the package and used the local address but the result was the same.
You need to do this from the command line before starting Sage. Otherwise you can use
sage: install_package("wxPython")
which is currently downloading for me... and then failed:

Along those lines, here is what it says at the list of experimental spkgs, of which this is one:
These are EXPERIMENTAL! They probably won't work at all for you! Use at your own risk! Many of these have never been successfully built on any platform!
So buyer beware!

I've just installed virt-manager with pkgin on NetBSD 9.2 just because I want to emulate the virtual machines with qemu + nvmm on NetBSD 9.2. The installation of virt-manager went ok. But,when I ran it,an error came up :
netbsd-marietto# virt-manager
Traceback (most recent call last):
File "/usr/pkg/share/virt-manager/virt-manager.py", line 386, in <module>
main()
File "/usr/pkg/share/virt-manager/virt-manager.py", line 247, in main
from virtManager import cli
File "/usr/pkg/share/virt-manager/virtManager/cli.py", line 29, in <module>
import libvirt
ImportError: No module named libvirt
Googling a little bit maybe I've found the solution here :
https://www.unitedbsd.com/d/285-linux-user-and-netbsd-enthusiast-hoping-to-migrate-some-day
where "kim" said :
Looking at pkgsrc/sysutils/libvirt/PLIST it doesn't look like the package provides any Python bindings -- which is what the "ImportError: No module named libvirt" error message is about. You could try py-libvirt from pkgsrc-wip and see how that works out.
I tried to start the compilation like this :
netbsd-marietto# cd /home/mario/Desktop/pkgsrc-wip/py-libvirt
netbsd-marietto# make
but I've got this error :
make: "/home/mario/Desktop/pkgsrc-wip/py-libvirt/Makefile" line 15: Could not find ../../wip/libvirt/buildlink3.mk
make: "/home/mario/Desktop/pkgsrc-wip/py-libvirt/Makefile" line 16: Could not find ../../lang/python/distutils.mk
make: "/home/mario/Desktop/pkgsrc-wip/py-libvirt/Makefile" line 17: Could not find ../../mk/bsd.pkg.mk

If u want to see the content of the Makefile,it is :

Can someone help me to fix the error ? very thanks.
You are getting those errors because your copy of pkgsrc wip is not inside a pkgsrc tree.
Please follow the pkgsrc wip documentation to correctly use pkgsrc wip. Especially look at the section titled Getting the "source".
In brief, assuming you have a copy of pkgsrc in /usr/pkgsrc and you want to use git to checkout pkgsrc wip, run these commands:
cd /usr/pkgsrc
git clone git://wip.pkgsrc.org/pkgsrc-wip.git wip
Then build py-libvirt with these commands:
cd /usr/pkgsrc/wip/py-libvirt
make
If it builds successfully, you could install it with:
cd /usr/pkgsrc/wip/py-libvirt
make install
I've created a virtual environment using both virtualenv and pipenv and in the both cases it seems that sphinx is not able to figure out the correct Python version. I have installed Python 2.7 and Python 3.8 in my global environment.
The error shows up when I try to use sphinx-apidoc + make html. I'm on a Windows 10 machine. Because I'm using type annotations, I get this error:
(venv) C:\Users\eug\Documents\learning\learning-pdoc\docs>make html

As you can see I'm currently on the virtual environment (venv). Calling python by itself correctly calls the right version. In order to execute what I want I need to call:
python -m sphinx.cmd.build -M html . .
Which is not ideal. Is there a way to fix this?
I need to install megam for nltk classification routines in Python.
I followed the instruction by Milk Magic from this post:
0. Downloaded megam source from http://www.umiacs.umd.edu/~hal/megam/index.html
1. Installed cygwin with gcc, make and ocaml packages
2. changed the makefile
3. when trying to compile megam with a makefile I receive an error with the following content
make

sh: flexlink: command not found
File "fastdot_c.c", line 1:
Error: Error while building custom runtime system
make: *** [Makefile:101: megam] Error 2
Do you know what the problem might be?
Maybe somebody has solved the same problem recently and could help.
As the error is
sh: flexlink: command not found
you need to find the package that contains it
$ cygcheck -p flexlink
Found 5 matches for flexlink
flexdll-0.34-1 - flexdll: Creates DLLs with runtime symbol resolution (installed binaries and support files)
flexdll-0.35-1 - flexdll: Creates DLLs with runtime symbol resolution (installed binaries and support files)
flexdll-0.35-2 - flexdll: Creates DLLs with runtime symbol resolution
...
So you need to install the flexdll package.
$ cygcheck -l flexdll |grep bin
/usr/bin/flexlink
I installed Python 3.4.0 64 bit and gdal file release-1400-x64-gdal-1-11-1-mapserver-6-4-1.zip from http://www.gisinternals.com/release.php. I found the binding from http://www.lfd.uci.edu/~gohlke/pythonlibs/#gdal and the filename is GDAL-1.11.2-cp34-none-win_amd64. I successfully install these files and import gdal. However, when I run the following command within the Python IDE to merge files 1 2 and 3, I got an error
>>> gdal_merge.py -o out.tif 1.tif 2.tif 3.tif
File "<console>", line 1
gdal_merge.py -o out.tif 1.tif 2.tif 3.tif
^
SyntaxError: invalid syntax
I specifically check to see if I can import gdal_merge as below
>>> import gdal_merge
and it was ok.
I appreciate if anybody could help with this issue.
gdal_merge.py is part of the GDAL utilities which are executed from the command line, not from within a Python IDE or another Python script.
Just open a command line (cmd) and type:
python gdal_merge.py -o out.tif 1.tif 2.tif 3.tif
Depending on your environment variables and whether you included GDAL in your Path variable you might need to specificy the full path to gdal_merge.py and/or can leave out python at the beginning of the call.
On one of my Windows 7 development machines, I am attempting to install the Python Image Library.
My machines are similar. Both run Windows 7 Professional, x64. Both use Python 2.7.3 (32bit). On one of the machine pip install PIL works fine. On the other it fails with the trace ending with this:
build\temp.win-amd64-2.7\Release\_imaging.pyd.manifest : general error c1010070:
Failed to load and parse the manifest. The system cannot find the file specified.
error: command 'mt.exe' failed with exit status 31
How can I resolve this error?
Thanks to http://bugs.python.org/issue4431, this error was fixed by modifying:
C:\<Python dir>\Lib\distutils\msvc9compiler.py
and adding:
ld_args.append('/MANIFEST')
after the MANIFESTFILE line so it looks like:
# Embedded manifests are recommended - see MSDN article titled
# "How to: Embed a Manifest Inside a C/C++ Application"
# (currently at http://msdn2.microsoft.com/en-us/library/ms235591(VS.80).aspx)
# Ask the linker to generate the manifest in the temp dir, so
# we can embed it later.
temp_manifest = os.path.join(
build_temp,
os.path.basename(output_filename) + ".manifest")
ld_args.append('/MANIFESTFILE:' + temp_manifest)
ld_args.append('/MANIFEST')
If you still get the error, then change the if arg.startswith("/MANIFESTFILE:") to if arg.startswith("/MANIFEST:") in the manifest_get_embed_info(self, target_desc, ld_args) method.
Download the compressed package from pypi, and try building and installing in your machine. This link could give you some hints. That exactly deals with your problem only but the installation varies.
If you've reached here looking for
general error c1010070:
Failed to load and parse the manifest. The system cannot find the file specified.
error: command 'mt.exe' failed with exit status 31
Here's a workaround that worked in Windows 8/x64/Python 3.3/VS 11:
# py 3.3 seems to be compiled against VS 2010 compiler, force using VS11 cl.exe for us
$env:VS100COMNTOOLS=$env:VS110COMNTOOLS
# Modify C:\Python33\lib\distutils\msvc9compiler.py
# Comment line 670: ld_args.append('/MANIFESTFILE:' + temp_manifest)
# Basically it will instruct build to not look for manifest file
