Answer 1

Agree with Dixit.

First Solution:

It's okay to use pip3 install sympy on MacOS.

1. List item
2. Open your "Terminal".
3. Input pip3 install sympy and press enter.
4. It will automatically download and install the Sympy Package.

Second Solution:

Using git. # Notice: Before install Sympy, it's necessary to install "mpmath". Like the First Solution,

• 1) Open "Terminal";
• 2) Input pip3 install mpmath

After installing "mpmath", then,

1. List item
2. Open your "Terminal" on MacOS or "win+r", then input "cmd" in Windows.
3. Input "git clone git://github.com/sympy/sympy.git" and press enter;
4. Input "python setup.py install"

After finish installation, you can open the Python IDLE and try:

from sympy import Symbol, cos
x = Symbol('x')
e = 1/cos(x)
print(e.series(x, 0, 10))
# Result
# 1 + x**2/2 + 5*x**4/24 + 61*x**6/720 + 277*x**8/8064 + O(x**10)

If the code works, it shows that your "Sympy" package has already been installed.

Answer 2

In anaconda navigator:

1. Click Environments (on the left)
2. Choose your environment (if you have more than one)
3. On the middle pick "All" from dropbox ("installed" by default)
4. Write sympy in search-box on the right
5. Check the package that showed out
6. Click apply
