No module named 'spyderlib'

[Rietaros]

I found this error :

Traceback (most recent call last):
  File "spyder.py", line 2, in <module>
    from spyderlib import start_app
ImportError: No module named spyderlib

while running : python spyder.py

In my Linux Anaconda virtual environment. Any idea how to fix this?

*Before I found that error, I did some update using conda update --all

thank you in advance #

The spyderlib module was renamed to spyder when Spyder 3.0 was released. So you need to verify that you have the latest Spyder version installed.

I try to launch it from Anaconda

ubuntu@ubuntu:~/anaconda3/bin$ python spyder.py
Traceback (most recent call last):
  File "spyder.py", line 2, in <module>
    from spyder import start_app
  File "/home/ubuntu/anaconda3/bin/spyder.py", line 2, in <module>
    from spyder import start_app
ImportError: cannot import name 'start_app'

I found that if I use spyder2 for python2, there's no error.

And this is spyder related library for python2 in my PC:

• spyderlib
• spyderplugins

spyder related library for python3 im my PC:

• spyder
• spyder_breakpoints
• spyder_io_dcm
• spyder_io_hdf5
• spyder_profiler
• spyder_pylint

Why there's still an error for my launcher?

Do you have two versions of Anaconda installed?

[Rietaros]

Nope, just Anaconda3 for my Python3 Virtual Environment. While Python2 is my default Python for Linux. I installed Spyder from Anaconda3.

But, the problem only appear when I launch Spyder3 from Anaconda launcher (which is called from spyder.py).
