Question

Update
Thanks for the hint by #cel below, the command to use is
>sudo conda install sympy=1.4
## Package Plan ##
environment location: /opt/anaconda
added / updated specs:
- sympy=1.4
The following packages will be downloaded:
package | build
---------------------------|-----------------
sympy-1.4 | py37_0 9.7 MB
------------------------------------------------------------
Total: 9.7 MB
The following packages will be REMOVED:
anaconda-2019.03-py37_0
The following packages will be UPDATED:
sympy 1.3-py37_0 --> 1.4-py37_0
Proceed ([y]/n)? y
Verified OK after installation:
>python
Python 3.7.3 (default, Mar 27 2019, 22:11:17)
[GCC 7.3.0] :: Anaconda, Inc. on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> import sympy
>>> sympy.__version__
'1.4'

I have no idea why other commands did not work. But the above works.
Original question
I am using Linux Manjaro 64 bit. Installed latest Anancoda
>which python
/opt/anaconda/bin/python
>conda list anaconda
# packages in environment at /opt/anaconda:
#
# Name Version Build Channel
anaconda 2019.03 py37_0
anaconda-client 1.7.2 py37_0
anaconda-navigator 1.9.7 py37_0
anaconda-project 0.8.2 py37_0
The problem is that it comes with sympy 1.3, while latest sympy is 1.4 accoding to
https://github.com/sympy/sympy/releases
sympy 1.4 has been out 3 weeks ago.
Now doing
>sudo conda update sympy
Does not update. It says
## Package Plan ##
environment location: /opt/anaconda
added / updated specs:
- sympy
The following packages will be downloaded:
package | build
---------------------------|-----------------
ca-certificates-2019.1.23 | 0 126 KB
certifi-2019.3.9 | py37_0 155 KB
conda-4.6.14 | py37_0 2.1 MB
openssl-1.1.1b | h7b6447c_1 4.0 MB
sympy-1.3 | py37_0 9.5 MB
------------------------------------------------------------
Total: 15.9 MB
But according to https://anaconda.org/anaconda/sympy it says sympy 1.4 is available
I also tried the command above, and it does not update sympy
>sudo conda install -c anaconda sympy

Any one knows why sympy is not being updated? Anything else to try? I could download the tar file from sympy 1.4, but I do not know what to do after that in order to install it in Anancoda.

When conda update does not want to update a package, you can ask conda explicity to install a specific version: conda install sympy=1.4.
