Python script cannot access imported package files due to lack of permission

Question

We recently installed pykakasi package from Git on Linux server on BigData Cluster.

After installation I tried the test program from "Readme" and received this error.

Error Received:

PermissionError: [Errno 13] Permission denied: '/opt/python/python35/lib/python3.5/site-packages/pykakasi/kanwadict3.db/data'

I tried to research all the issues reported on Git. Also, searched this and other forums for possible solution but nothing worked.

Program I was testing:

import pykakasi

text = u"かな漢字交じり文"
kakasi = pykakasi.kakasi()
kakasi.setMode("H","a") # Hiragana to ascii, default: no conversion
kakasi.setMode("K","a") # Katakana to ascii, default: no conversion
kakasi.setMode("J","a") # Japanese to ascii, default: no conversion
kakasi.setMode("r","Hepburn") # default: use Hepburn Roman table
kakasi.setMode("s", True) # add space, default: no separator
kakasi.setMode("C", True) # capitalize, default: no capitalize
conv = kakasi.getConverter()
result = conv.do(text)
print(result)

Expected Output: kana Kanji Majiri Bun

Detailed Error:

It works in my local `kana Kanji Majiri Bun` is printed out, something is wrong with your installation location of the `pykakasi` package, and the folder access permission seems to be the problem... Can you check the permissions of the said folder & the file? — buræquete, Jun 20 '19 at 03:37
Thank you for quick response...I can't change any folder permissions as it needs root access — Sam S, Jun 20 '19 at 03:38
You can try to first install the `pykakasi` in a folder that has your permission, check [this](https://stackoverflow.com/questions/2915471/install-a-python-package-into-a-different-directory-using-pip) then try to import it within your script via [import from path](https://stackoverflow.com/questions/4383571/importing-files-from-different-folder) otherwise you'd need to run the script as root I think... — buræquete, Jun 20 '19 at 03:42
Did my answer help you to resolve the trouble? If so please accept it, or let me know if I can help any further! — buræquete, Aug 02 '19 at 09:54

I had the similar issue before, what I had done was that getting the imported packages in my local, e.g.

~/myLocal/code.py
~/myLocal/package/... -> contains the package that is used in code.

To do that, you can use something from here to install the desired package in a custom path. Or find some other way to achieve this. In the end you can just refer to this package with path as detailed here

Something like;

# code.py
import package.targetPackage as targetPackage
...
