As such, I have created a virtual environment so I can use modules as I need without installing them fully on the system.\r\n\r\nI experienced an error when trying to use Latex as a text renderer for plots I am making for publication in my virtual environment. \r\nI 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.\r\n\r\nI am aware a similar issue was raised [here](https://github.com/matplotlib/matplotlib/issues/5076/) 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?\r\n\r\nThanks in advance.\r\n\r\n**Code for reproduction**\r\n\r\n\u003c!--A minimum code snippet required to reproduce the bug.\r\nPlease make sure to minimize the number of dependencies required, and provide\r\nany necessary plotted data.\r\nAvoid using threads, as Matplotlib is (explicitly) not thread-safe.--\u003e\r\n\r\n```python\r\nimport matplotlib as mpl\r\nmpl.use('Agg') # Use this backend for writing plots to file\r\n\r\nimport matplotlib.pyplot as plt\r\nplt.style.use('seaborn-talk')\r\nmpl.rcParams['figure.figsize'] = [10, 8]\r\nmpl.rcParams['figure.autolayout'] = True\r\nmpl.rcParams['text.usetex'] = True                     # \u003c------- This seems to be issue\r\nmpl.rcParams['font.family'] = 'serif'\r\nmpl.rcParams['font.serif'] = 'Computer Modern Roman'\r\nmpl.rcParams['lines.linewidth'] = 1.25\r\nmpl.rcParams['lines.markersize'] = 6\r\n\r\n# Simple Plot of Data\r\nplt.plot(np.arange(10), np.sin(np.arange(10)))\r\nplt.xlim(0, 2*np.pi)\r\nplt.ylim(-3.2, 3.2)\r\nplt.xlabel(r'$x$')\r\nplt.ylabel(r'$u(x, t) / u_{rms}(x,
