Bug report

Bug summary

Hi,

I am working on a linux system which I do not have root privileges to. As such, I have created a virtual environment so I can use modules as I need without installing them fully on the system.

I experienced an error when trying to use Latex as a text renderer for plots I am making for publication in my virtual environment.
I do not get an error and everything works fine when I run the same code snippet outside of my virtual environment and I need to work in my virtual environment as there are certain modules I need to compute other parts the code.

I am aware a similar issue was raised here the resolution appears to be reinstall/update whatever Tex distribution I have but I can not do that as I do not have root privileges on my system. So is there a work around I could use in my vitual environment?

Thanks in advance.

Code for reproduction

import matplotlib as mpl
mpl.use('Agg') # Use this backend for writing plots to file

import matplotlib.pyplot as plt
plt.style.use('seaborn-talk')
mpl.rcParams['figure.figsize'] = [10, 8]
mpl.rcParams['figure.autolayout'] = True
mpl.rcParams['text.usetex'] = True                     # <------- This seems to be issue
mpl.rcParams['font.family'] = 'serif'
mpl.rcParams['font.serif'] = 'Computer Modern Roman'
mpl.rcParams['lines.linewidth'] = 1.25
mpl.rcParams['lines.markersize'] = 6

# Simple Plot of Data
plt.plot(np.arange(10), np.sin(np.arange(10)))
plt.xlim(0, 2*np.pi)
plt.ylim(-3.2, 3.2)
plt.xlabel(r'$x$')
plt.ylabel(r'$u(x, t) / u_{rms}(x, t)$')
plt.show()

    The problem is a missing latex package that we began to require someplace between mpl 2.1.1 and mpl 3.2.2.

    See #16911 and links there in which chases back to #11381 .

    I think the solution is to either get cm-super (which is the source of type1ec.sty https://ctan.org/pkg/cm-super) installed on your system by the sysadmins or get a local install of latex.
