Questions[spyder](ubuntu)

I want to install latest version of Spyder on Ubuntu 18.04. I need to update Spyder to the latest version (spyder 3.3.2), because there are some errors with version 3.2.6 such as variable explorer doesn't show variables. I don't use Anaconda, and I don't want to install it with Anaconda.

When I tried to install it with pip install -U spyder I got the following error:

Could not install packages due to an EnvironmentError: [Errno 2] No such file or directory: '/home/candan/.local/lib/python2.7/site-packages/QtPy-1.6.0.dist-info/METADATA'

The full result is here:

    candan@candan-HP-ProBook-470-G2:~$ pip install -U spyder
DEPRECATION: Python 2.7 will reach the end of its life on January 1st, 2020. Please upgrade your Python as Python 2.7 won't be maintained after that date. A future version of pip will drop support for Python 2.7.

I also tried to install it manually by downloading package Spyder 3.3.2, but it didn't work.

I can run the old version when I install it by using Ubuntu Software, but it is not the latest version. How can install the latest version of Sypder properly?

Edit:

For Python 2.7 I'm using following command to update:

pip install --upgrade spyder

If the above command doesn't work add --user after install.

For Python 3:

python3 -m pip install --user --upgrade spyder 

I have freshly installed Ubuntu 18.04 and Anaconda (with Python 3.7) in my laptop, and I want to set up a launcher icon for the Spyder IDE in the Favourites bar - something I've done many times in the past couple of years when running Ubuntu 16.

I can successfully launch Spyder from the Terminal and it seems to be working fine, but when I run it from the terminal and right-click the icon, it does not give me an option for adding it to Favorites.

[Strangely, searching for an application named "spyder" returns no results; not sure if this might be related, but...]

I understand I can manually add an icon for it by creating a .desktop file, as described here and here, and adding it to /usr/share/applications, as described here. For example, I have tried using the following spyder.desktop file (available in the Spyder Github):

[Desktop Entry]
Type=Application
Version=1.0
Name=Spyder
GenericName=Spyder
Comment=The Scientific Python Development Environment
Icon=spyder
TryExec=spyder
Exec=spyder %F
Terminal=false
MimeType=text/x-python;
Categories=Development;Science;IDE;Qt;
Keywords=Development;Science;IDE;Qt;
StartupNotify=true
X-AppStream-Ignore=True
StartupWMClass=Spyder

However, even after creating this file, Spyder still does not show up in Applications. And if I try to run this file, I get a fairly generic

"There was an error launching the application"

message.

Is this a known issue with Spyder and/or Ubuntu 18? Am I missing something here? Any help would be much appreciated! Many thanks!

I tried for some reason to uninstall Spyder (using purge --auto-remove and all) from Ubuntu 16.04. Apparently Spyder is now uninstalled, but

which spyder

gives

/usr/local/bin/spyder

and I can still launch Spyder.

How do I completely uninstall Spyder ?

I just installed Anaconda 4.5.8 and Spyder via both conda install spyder and sudo apt-get install spyder3.

I run Spyder via spyder using terminal and the variable explorer works perfectly. But when I run via Spyder3 at Application Menu, I got this error:

Spyder was unable to retrieve the value of this variable from the console.
The error mesage was: ModuleNotFoundError("No module named 'numpy'",)

I use a simple one like a = np.arange(0, 10, 1). It also fails on pandas DataFrame object.

It seems the system runs different Spyder from terminal and from Application menu. How do I fix this? I think it's too slow if I need to run it via terminal. I want the same Spyder just like the terminal's but launch it via Application Menu instead.

PS: I change the Spyder's Application Menu Python Interpreter to Anaconda's folder /home/hermonjay/anaconda3/bin/python3.6 and still got an error on the variable explorer.

Spyder's Anaconda version is 3.2.8 and Application is 3.2.6.

i installed spyder3 and tried to add its launcher to the gnome panel. i could not get this to work... i tried several things:

1. i launched spyder3 and clicked on its icon in the panel hoping for an 'Add to Favourites' menu item - there is none.

2. i looked for a .desktop file ($ dpkg -L spyder3 | grep '\.desktop'). it exists and is located at /usr/share/applications/spyder3.desktop. i tried to drag+drop that to the panel. that did not work either.

3. i tried to add spyder3.desktop on the command-line to the settings favourites (something like $ gsettings set org.gnome.shell favorite-apps "['firefox.desktop', ..., 'spyder3.desktop']"). logged out & in again. also that did not work.

4. i tried to create a custom spyder3 launcher using $ gnome-desktop-item-edit. that does create an (executable) .desktop file but i could not add it to the launcher either.

is there a way to add a launcher for spyder3? how?
