Hello Replit Community,
I’m working on an academic research project and have encountered a persistent and challenging issue with importing the
pandas library in my Python script. Despite successful installation, the library seems to be inaccessible when running the script. I’m detailing the issue below and would greatly appreciate any guidance or insights from the community.
After successfully installing
pandas, my Python script fails to import it, throwing a
Installing collected packages: six, tzdata, pytz, python-dateutil, numpy, pandas
Successfully installed numpy-1.26.2 pandas-2.1.4 python-dateutil-2.8.2 pytz-2023.3.post1 six-1.16.0 tzdata-2023.3
~/jrope$ python main.py
Traceback (most recent call last):
File "/home/runner/jrope/main.py", line 10, in <module>
import pandas as pd
ModuleNotFoundError: No module named 'pandas'
- I initially installed
pip and encountered the above
ModuleNotFoundError when attempting to import it in my script.
- I created a new environment and tried managing dependencies with Poetry, but faced further issues, including uncertainty whether Python 3.9 or Python 3.10 was being used.
- I observed that
pandas is present in the “.pythonlibs” and “.config” directories, yet it’s not recognized in the script.
- Attempting to use
poetry shell resulted in an assertion error.
- Network and permission-related errors arose when using Poetry for installations.
Given these challenges, I’m seeking advice or solutions to address this problem. I’ve tried restarting the workspace and verifying Python versions for compatibility, but the issue persists.
Any help or suggestions from the community would be greatly appreciated. Thank you in advance for your time and assistance.
could you share your
replit.nix file contents? (It is hidden by default, Show hidden files in three dots first.)
echo $PYTHONPATH in the shell and share the output.
I suspect that
PYTHONPATH has been corrupted by a nix dependency or by pip. The general workaround is this:
Show hidden files, then open .replit file.
Near the bottom, insert this (if there is an existing
[env] section, use that instead):
PYTHONPATH = "$REPL_HOME/.pythonlibs/lib/python3.10/site-packages:$PYTHONPATH"
Hello Replit Community,
I’ve been following the advice from NuclearPasta0 about fixing a
PYTHONPATH issue by editing the
.replit file. Despite these efforts, I’ve run into several complex problems:
import pandas resulted in
- After modifying
PYTHONPATH = "$REPL_HOME/.pythonlibs/lib/python3.10/site-packages:$PYTHONPATH", I faced a new error:
ImportError: libstdc++.so.6: cannot open shared object file: No such file or directory.
- Attempting to reinstall
pandas led to a syntax error in the
Given these challenges, I decided to transfer my scripts to a new Replit workspace. However, I’m still keen to understand what went wrong in the original setup. Any insights or explanations would be greatly appreciated.
Thank you, NuclearPasta0, for your suggestions, and thank you to anyone who can shed light on these issues.
The 1st problem can always be investigated easily. If the package is present and in
PYTHONPATH, it can be imported.
I took a look at your repl (next time, provide a direct link to it) and found several problems.
- In your
.replit file, you set
PYTHON_LD_LIBRARY_PATH. Normally, this shoudn’t be much of a problem. However, I think that it should be appended rather than overwriting it. Also, apparently you should be able to just put any library dependencies directly in
replit.nix, because replit has its own
REPLIT_LD_LIBRARY_PATH variable that is used for everything.
- In your
replit.nix file, you have a dep in
nix-update. (It would be useful to know why this is here, which package needs this?). I know that
nix-update has a bug on replit that overwrites
PYTHONPATH, requiring the
PYTHONPATH modification workaround in my last post.
.pythonlibs/lib/python3.10/site-packages, there is apparently a
concurrent package. But I’m not sure why that’s there. It is supposed to be a builtin library. Removing it should be fine.
- In replit, it is not recommend to use
requirements.txt and not recommended to use
pip. It can sometimes lead to problems. (Also note that
apt are not usable in replit.) Always use poetry instead.
