I am trying to use python 3 virtual environment on Kubuntu 17.04 (same error on Kubuntu 16.10).
The python packages are installed by using apt and not by some other source such as pip to do the virtual environment. The same code is running in a Windows environment. So it seems to me an OS issue rather than a python issue. It does not find any library I install using pip within the virtual environment. I did the following steps:
user@computer:~/development/python/testDB$ python3.6 -m venv /home/user/development/python/testDB/ user@computer:~/development/python/testDB$ source bin/activate (testDB) user@computer:~/development/python/testDB$ pip install pymysql Collecting pymysql Using cached PyMySQL-0.7.11-py2.py3-none-any.whl Installing collected packages: pymysql Successfully installed pymysql-0.7.11 (testDB) user@computer:~/development/python/testDB$ ./testDB.py ['/home/user/development/python/testDB', '/usr/lib/python35.zip','/usr/lib/python3.5', '/usr/lib/python3.5/plat-x86_64-linux-gnu', '/usr/lib/python3.5/lib-dynload', '/home/user/.local/lib/python3.5/site-packages', '/usr/local/lib/python3.5/dist-packages', '/usr/lib/python3/dist-packages'] Traceback (most recent call last): File "./testDB.py", line 4, in <module> import pymysql ImportError: No module named 'pymysql' (testDB) user@computer:~/development/python/testDB$ python --version Python 3.6.1
The path to
is not set and therefore the library is not found.
The script is very simple:
#!/usr/bin/python3 import sys print(sys.path) import pymysql
I do not see where I do the error. Can anybody please help?

I did some additional testing and reconfiguration.... unfortunately the error does not vanish. Listing of the pip3 installed packages are:
sudo pip3 freeze apt-xapian-index==0.47 apturl==0.5.2 chardet==2.3.0 command-not-found==0.3 cryptography==1.7.1 defer==1.0.6 distro-info===0.14build1 idna==2.2 keyring==10.3.1 keyrings.alt==2.2 language-selector==0.1 pdb-clone==1.10 pexpect==4.2.1 Pillow==4.0.0 ptyprocess==0.5.1 pyasn1==0.1.9 pyclewn==2.3 pycrypto==2.6.1 pycups==1.9.73 pycurl==7.43.0 Pygments==2.2.0 pygobject==3.22.0 python-apt==1.4.0b2 python-debian==0.1.30 pyxdg==0.25 PyYAML==3.12 reportlab==3.3.0 requests==2.10.0 SecretStorage==2.3.1 six==1.10.0 systemd-python==233 ubuntu-drivers-common==0.0.0 ufw==0.35 unattended-upgrades==0.1 urllib3==1.15.1 usb-creator==0.3.3 xkit==0.0.0 virtualenv==15.1.0
Pyhton 3 packages installed with apt for the virtual environment are:
apt list --installed |grep python3-v WARNING: apt does not have a stable CLI interface. Use with caution in scripts. python3-venv/zesty,now 3.5.3-1 amd64 [installed] python3-virtualenv/zesty,zesty,now 15.1.0+ds-1 all [installed]
I removed all packages and reinstalled it. Do now use Python 3.5, however it didn't help.
