I am trying to follow the Django-autocomplete-light tutorial
However, when I try to run the test_project, I get the following error.
AttributeError: module 'dal.autocomplete' has no attribute
'Select2GenericForeignKeyModelField'
When I check the dal/autocomplete.py which was installed through pip command, I could not find any attribute Select2GenericForeignKeyModelField.
On the other hand, when I check the one in github, I could find this attribute.
I am guessing that the version which is in pip is older than the one in github.
Does anyone know how I can solve this problem?
The latest stable version is DAL 3.2.10, it was released at Aug 28, 2017 and Select2GenericForeignKeyModelField was added at Mar 30, 2018. It's not available even in pre-releases as the most recent pre-release now is 3.3.0rc6 released at Mar 6, 2018.
It seems you have to use older API or install DAL from Github:
pip install -U git+https://github.com/yourlabs/django-autocomplete-light#egg=django-autocomplete-light

Recently I have been installed Python 3.8.2 ( Feb 24, 2020) (64bit, Windows). Afterward, I've been updated Pip 20.0.2. And then trying to install Unittest" pip install unittest" but unfortunately it's appearing this message.
Does anyone has been faced this same problem?
C:\Users\BiploB>pip install unittest --user
WARNING: pip is being invoked by an old script wrapper. This will fail in a future version of pip.
Please see https://github.com/pypa/pip/issues/5599 for advice on fixing the underlying issue.
To avoid this problem you can invoke Python with '-m pip' instead of running pip directly.
ERROR: Could not find a version that satisfies the requirement unittest (from versions: none)
ERROR: No matching distribution found for unittest

If I am not mistaken unittest is part of Python's standard library. Meaning, it's available per default, meaning there is no need (and also no way) to install separately.
I was installing nvidia-drivers on Centos 6.10 which included a --skip-broken flag and may have broken yum. Whenever I ran yum commands this error pops up.
There was a problem importing one of the Python modules
required to run yum. The error leading to this problem was:
/lib64/libc.so.6: version `GLIBC_2.14' not found (required by /lib64/libgcc_s.so.1)
Please install a package which provides this module, or
verify that the module is installed correctly.
It's possible that the above module doesn't match the
current version of Python, which is:
2.6.6 (r266:84292, Jun 20 2019, 14:14:55)
[GCC 4.4.7 20120313 (Red Hat 4.4.7-23)]
If you cannot solve this problem yourself, please go to
the yum faq at:
http://yum.baseurl.org/wiki/Faq
I stumbled upon this thread which talks about installing the missing GLIBC version, but I ran into this error in step 8 ../configure --prefix=/opt/glibc-2.14
checking for forced unwind support... no
configure: error: forced unwind support is required
Which then took me to this forum thread that states I should install libunwind via yum. Which was my original problem, thus leaving me at an impasse. What should I do?
You need to reinstall GCC, or more precisely the libgcc package. Something overwrote /lib64/libgcc_s.so.1 with an incompatible version. You should be able to download the libgcc RPM package from a mirror, and then run:
# rpm --reinstall libgcc-4.4.7-23.el6.x86_64.rpm
This should still work because RPM itself does not depend on libgcc_s.
In general, if you need newer versions of these core system libraries (glibc, libstdc++, libgcc_s), you need to upgrade the entire operating system. Even if you manage to replace them in a consistent fashion, you are running something that isn't very close to the original operating system anymore. At that point, it is more prudent to upgrade, because that will give you a consistent system that has been tested by many others.
I have been trying to install obspy and have been running into a lot of problems. I want to install obspy which has a dependency on pyproj. But apparently obspy only works with pyproj 1.9.5.1, which I tried installing using pip (pip3 install pyproj==1.9.5.1), but only got the errors like-
_proj.c:7488:13: error: ‘PyThreadState’ {aka ‘struct _ts’} has no member named ‘exc_traceback’; did you mean ‘curexc_traceback’?
Digging deeper I found that it might be a Cython problem, and installing pyproj directly from github might help, because it would apparently make Cython recompile all the necessary files. Something along the lines of -
pip3 install git+https://github.com/jswhit/pyproj.git
However this one gives the error -
ERROR: Minimum supported proj version is 6.2.0, installed version is 5.2.0.
I di try installing a higher version of libproj-dev (sudo apt install libproj-dev=6.2.0) however it shows that there is no candidate for 6.2.0. I tried downloading the deb file and installing from that using -
sudo apt-get install ~/Downloads/libproj-dev_6.2.0-1_amd64.deb
which just leads to the error -
The following packages have unmet dependencies:
libproj-dev : Depends: libproj15 (= 6.2.0-1) but it is not installable
E: Unable to correct problems, you have held broken packages.
But I think this is not the right way to install for me anyway, since I need a specific version. Hence I tried installing directly from the tarball of the release -
pip3 install https://github.com/pyproj4/pyproj/archive/v1.9.5.1rel.tar.gz
Which leads to the first error I had, evidently due to Cython.
With errors on everything I tried to do to fix this, I am not sure what even is relevant to my problem now.
Any help is appreciated, and if this site is not the correct place for this question, please help me migrate it to its proper destination.
I am on Ubuntu 18.10.
The problem is, that Cython-generated c-files don't work for Python-3.7 if generated with Cython versions up to 0.27.3 (at least): The setup.py of pyproj (at least in the version 1.9.5.1) doesn't regenerate the_proj.c, which is generated with Cython 0.23.2 and thus the installation cannot succeed.
You have the following options:
stay on Python3.6 where everything works out of the box.
regenerate _proj.c with a current Cython-version.
For the second option:
download and unzip your prefered version from https://github.com/pyproj4/pyproj/releases/tag/v1.9.5.1rel and switch to the created folder pyproj-1.9.5.1rel.
check, that the cython-version is >=0.27.3. via cython --version.
regenerate the _proj.c file via cython -3 _proj.pyx (_proj.pyx looks like Python3-code, but also language_level=2 (i.e. cython -2 _proj.pyx) will probably work.
install running pip install .
pyproj 1.9.5.1 was release at Jan 7, 2016. At that time, the latest version Python was 3.5. In my tests. pyproj 1.9.5.1 failed to be installed on Python 3.7.4, but succeeded on Python 3.5.7.
You need to create a environment with Python 3.5 by pyenv or conda.

I use go.net/html in my project on work and everything is ok. But when I try to install this package on my laptop I get a error:
termith#termith-laptop:~/go$ go get code.google.com/p/go.net/html

Thanks in advance!
You most likely have an outdated Go version (see for example this GitHub issue).
Check the output of go version and update if necessary.
Beware: the go.net package url will change with Go 1.4:
code.google.com/p/go.net => golang.org/x/net
If you update (again) your go version (to 1.4, once released, November 9th, 2014), you might have to change that import path.
See "Go 1.4 subrepo renaming".
I'm using CentOS Linux release 6.0 (Final) but unable install given package
1) rpm -ivh oracle-instantclient11.2-devel-11.2.0.1.0-1.x86_64.rpm
Whenever i install package,I got following error
error: Failed dependencies:
oracle-instantclient11.2-basic >= 11.2.0.1.0 is needed by oracle-instantclient11.2-devel-11.2.0.3.0-1.x86_64
2)rpm -ivh oracle-instantclient11.2-devel-11.2.0.1.0-1.x86_64.rpm
Whenever i install package,I got following error
error: Failed dependencies:
oracle-instantclient11.2-basic >= 11.2.0.1.0 is needed by oracle-instantclient11.2-devel-11.2.0.1.0-1.x86_64
From the instant client information page:
Installation Instructions
Installation Steps:
Download the appropriate Instant Client packages for your platform. All installations REQUIRE the Basic or Basic Lite package.
...
That is referring to the .zip version, but the same will apply to the .rpm version.
So you need to get and install the oracle-instantclient11.2-basic-11.2.0.1.0-1.x86_64.rpm or oracle-instantclient11.2-basiclite-11.2.0.1.0-1.x86_64.rpm (Basic Lite: Smaller version of the Basic, with only English error messages and Unicode, ASCII, and Western European character set support) before you can install the -devel- package on top.
Kind of curious that you're installing the 11.2.0.1 version (or 11.2.0.3 from your first error message, despite the command you showed) when more recent versions are available. I assume you're getting your .rpm files from the download site. I'd get the 11.2.0.4 version, if not the 12.0.0.1 version, unless you have a specific reason to stick to an older one. I would get the same version for basic and devel though, despite the message suggesting they don't have to match. So oracle-instantclient11.2-basic-11.2.0.3.0-1.x86_64.rpm (or basiclite) if you're sticking with oracle-instantclient11.2-devel-11.2.0.3.0-1.x86_64.rpm.
