Attempt to install psutils resulted a big headache...
$ python -V
Python 2.4.2
$ cat /etc/SuSE-release
SUSE Linux Enterprise Server 10 (x86_64)
VERSION = 10
PATCHLEVEL = 4
$ cd psutil-2.1.1/
$ python setup.py install
Traceback (most recent call last):
File "setup.py", line 17, in ?
from distutils.core import setup, Extension
ImportError: No module named distutils.core
Next - I try to install setuptools to use easy_install:
$ which easy_install
which: no easy_install
$ cd ../setuptools-1.4/
$ python setup.py install
Traceback (most recent call last):
File "setup.py", line 12, in ?
from distutils.util import convert_path
ImportError: No module named distutils.util
Trying install distutils from ez_setup.py:
$ python ez_setup.py
Traceback (most recent call last):
File "ez_setup.py", line 278, in ?
main(sys.argv[1:])
File "ez_setup.py", line 210, in main
egg = download_setuptools(version, delay=0)
File "ez_setup.py", line 139, in download_setuptools
from distutils import log
ImportError: No module named distutils
So - how can I install it?
P.S. No, I haven't root on this machine and can't use package manager.
you need to run this (if Error happens on python3) ==> sudo apt-get install python3-distutils --reinstall
you need to run this (if Error happens on python2) ==> sudo apt-get install python2-distutils --reinstall
I have an answer here but I will copy it here
AskUbuntu answer:
Debian has decided that distutils is not a core python package, so it is not included in the last versions of debian and debian-based OSes. You should be able to do sudo apt install python3-distutils and it should work.
However, it did not work for me. I use Parrot OS, which is, as Ubuntu, Debian based. I upgraded my system and pip stopped working for python3.7, and I also got the error ModuleNotFoundError: No module named 'distutils.util'
I tried a lot of stuff to fix it and to reinstall distutils, and I found out by pure luck, that pip3, for python3.8 did work. I then tried python3.7 -m pip3 -V, got /usr/bin/python3.7: No module named pip3 so I decided to have a look in the /usr/lib files.
I looked at /usr/lib/python3/dist-packages and everything looked fine. Then I looked at /usr/lib/python3.7 and saw the folder distutil.
I opened it, and saw the __pycache__, the __init__.py file and a version.py file. I had no idea how many files should be in there, or what the code should be, but I knew that those two files were either wrong or missing another file.
Then I had a look at what was inside /usr/lib/python3.8/distutil and it was totally different. I found the following files:
command Folder
__pycache__ Folder
archive_util.py Python script
bcppcompiler.py Python script
cmd.py Python script
config.py Python script
core.py Python script
cygwinccompiler.py Python script
debug.py Python script
dep_util.py Python script
errors.py Python script
extension.py Python script
fancy_getopt.py Python script
filelist.py Python script
file_util.py Python script
__init__.py Python script
log.py Python script
msvc9compiler.py Python script
_msvccompiler.py Python script
msvccompiler.py Python script
README Plain text file
spawn.py Python script
sysconfig.py Python script
text_file.py Python script
unixccompiler.py Python script
util.py Python script
version.py Python script
versionpredicate.py Python script
This was a lot more promising, and since pip3 did work, I assumed that this distutils worked too, and I tried to copy it to the python3.7 folder by running this command:
sudo cp -r /usr/lib/python3.8/distutil /usr/lib/python3.7/distutil
Then I tried again python3.7 -m pip -V and got
pip 20.0.2 from /usr/lib/python3/dist-packages/pip (python 3.7)
Then I tried installing some modules and everything works fine.
I hope this is helpful.

I need to do even more to get virtualenv running again (upgraded from 18.04 to 20.04):
sudo cp /usr/lib/python3.8/_sysconfigdata__* /usr/lib/python3.6/
cd /usr/lib/python3.6
sudo ln -s _sysconfigdata_m_linux_x86_64-linux-gnu.py _sysconfigdata_m_x86_64-linux-gnu.py

I can't import standard library modules (like ssl and tkinter) when I'm not running Python from "/Python3.8.10/Modules" directory:
/Python3.8.10/Modules/# python
>>> import ssl
Traceback(most recent call last):
File "<stdin>", line 1, in <module>
File "/usr/local/lib/python3.8/ssl.py", line 98, in <module>
import _ssl # if we can't import it, let the error propagate
ModuleNotFoundError: No module named '_ssl'
Same error happens if I try to import "_ssl" directly.
When I'm running Python in /Python3.8.10/Modules" directory everything works fine.
What could be causing this error?
I am using Debian and I used this tutorial https://linuxhint.com/install-python-debian-10/ to install it.
Judging from your comment you didn't install Python, but just downloaded and unzipped the Source Code.
I am on Debian. I unzipped (untar-ed) Python-3.8.10.tgz (Which comes from the Python website).
If you download the tar ball directly you still have to build Python by cd-ing into the Location you extracted it to and then running:
$ ./configure --enable-optimizations
$ make -j 4
$ sudo make altinstall # altinstall will install Python3.8 at /usr/bin/Python3.8 instead of /usr/bin/Python which could overwrite previously installed versions.
$ sudo ln -s /usr/bin/python /usr/bin/python3.8 # ONLY if you want Python3.8 to be available as just python
Edit: Those are just the commands that i remembered out of my head which worked for me on various systems. They also have some requirements (build-essentials and make being two of them) so this might not work for you.
See here or probably on any site when searching for build Python from source in your favorite search engine.
I can run the code below in Pycharm without issues, but when I create an exe using pyinstaller, I get the following error when I run the executable -
**Traceback (most recent call last):
File "openfile.py", line 1, in <module>
ImportError: No module named yaml
[1296] Failed to execute script openfile**
import yaml
from sys import exit
cfg = yaml.safe_load(open("Config.yml"))
exit()
Note that I'm using Windows 10.
pip install pyyaml will solve this problem
or use virtualenv
pip install virtualenv -p python3 #or python2
virtualenv venv
venv/Scripts/activate
pip install pyyaml
I have installed pyexiv2 on OSX El Capitan with homebrew but when trying to use it, it is not found.
$ brew install pyexiv2
Warning: pyexiv2-0.3.2_1 already installed

ImportError: No module named pyexiv2
Turns out when pyexiv2 was installed, brew had a quite significant output that I missed:
==> Caveats
Python modules have been installed and Homebrew's site-packages is not
in your Python sys.path, so you will not be able to import the modules
this formula installed. If you plan to develop with these modules,
please run:
mkdir -p /Users/YOUR_USER/Library/Python/2.7/lib/python/site-packages
echo 'import site; site.addsitedir("/usr/local/lib/python2.7/site-packages")' >> /Users/YOUR_USER/Library/Python/2.7/lib/python/site-packages/homebrew.pth
So you just have to run those two commands and it will work fine.
I just installed Gubbins using their homebrew instructions. Everything seemed to go smoothly and gubbins is now in /usr/local/Cellar/gubbins/1.1.1/bin/gubbins. I'm supposed to be able to use it by running their script run_gubbins.py and giving it an input file. But I get the following error:
>$ /usr/local/Cellar/gubbins/1.1.1/usr/bin/run_gubbins.py test.fasta
Traceback (most recent call last):
File "/usr/local/Cellar/gubbins/1.1.1/usr/bin/run_gubbins.py", line 25, in <module>
from gubbins import common
ImportError: No module named gubbins
Looking inside the run_gubbins.py script I see that the first things it does is
import sys
sys.path.append(".")
import argparse
from gubbins import common
So what might be happening? How come the script within a program package is not recognizing the program it came with? Is there anything I can do to fix this? Thank you so much.
Install homebrew from brew.sh

export PATH=~/Library/Python/2.7/bin:${PATH}
easy_install pip
pip install --user dendropy
pip install --user biopython

I am running Ubuntu 12.10 that has python 2.7 as its default. I have installed python 3.3 in /opt/python3.3 (using ./configure --prefix=/opt/python3.3) and have created a symlink /usr/bin/python33 that points to the executable in /opt. There is already a symlink /usr/bin/python3 that points to the python 3.2 (actually it points to python3.2mu: if you can explain as a side note as to why this 'mu' is included :) ) installation that came with the ubuntu installation.
I installed distribute tools using python3 without any problems. But when I tried the same thing with python33 it gave me the following error:
ankur#junk-mechanism:~$ sudo python33 distribute_setup.py
Extracting in /tmp/tmp685lyf
lzma module is not available
not a bzip2 file
gzip module is not available
bad checksum
Traceback (most recent call last):
File "distribute_setup.py", line 550, in <module>
sys.exit(main())
File "distribute_setup.py", line 547, in main
return _install(tarball, _build_install_args(options))
File "distribute_setup.py", line 78, in _install
tar = tarfile.open(tarball)
File "/opt/python3.3/lib/python3.3/tarfile.py", line 1578, in open
raise ReadError("file could not be opened successfully" + str(name) + repr(fileobj))
tarfile.ReadError: file could not be opened successfully/home/ankur/distribute-0.6.35.tar.gzNone
So in tarfile.py, the classmethod Tarfile.open calls the class method Tarfile.gzopen where the module gzip is imported:
try:
import gzip
gzip.GzipFile
except (ImportError, AttributeError):
raise CompressionError("gzip module is not available")
The error raised here is ImportError because gzip.py has an import zlib which it cant find. But even the other installations of python (2.7 and 3.2) dont contain zlib in the respective standard lib /usr/lib/pythonx.x/lib/. So what is the difference?
It sounds like you didn't build everything because of missing dependencies. You can try getting the missing dependencies and rebuilding. To get the missing dependencies, I'd just work from what Python 3.2 requires and do:
sudo apt-get build-dep python3
Then you can reconfigure and rebuild Python 3.3 to get all the required modules.
Another option is to use the dead snakes ppa:
sudo add-apt-repository ppa:fkrull/deadsnakes
sudo apt-get update
sudo apt-get install python3.3
I usually install the -dev package too so that I can install packages that have C extension modules:
sudo apt-get install python3.3-dev
