Thus, most install errors can be fixed by installing Mito inside of a virtual environment. If you are having any trouble with installing Mito, [**we reccomend you attempt to install Mito inside a virtual environment!**](https://docs.trymito.io/getting-started/installing-mito) ## Common Installation Issues #### The Sheet does not render when I call mitosheet.sheet(). This is the most common error, and it is likely because you have failed to refresh your Jupyter. This is usually fixable through the following steps: 1. Shut down all of the currently running Jupyter instances. 2. Close all browser tabs with Jupyter open. 3. Relaunch Jupyter. 4. Retry calling `mitosheet.sheet()` If this does not work, try rerunning the installer and repeating the above steps. #### The installer hit a Permission Error during install. If your installation fails with a `PermissionError`, then you likely will be able to successfully install Mito by rerunning the installation commands with adminstrator privileges. For Windows, this means[ running the command prompt as an admin](https://grok.lsu.edu/article.aspx?articleid=16850), and for Mac/Linux means using the sudo command for the installation commands. #### I'm getting an SSL error on MacOSX. You're probably receiving this error because you need to install the SSL certificates. * If you downloaded Python from the official website, then run `/Applications/Python\ 3.9/Install\ Certificates.command` in a terminal (change `3.9` to whatever version you installed). * If you installed Python using MacPorts, run `sudo port install curl-ca-bundle` in a terminal. If you have any other issues installing Mito, or you're looking to install Mito on JupyterHub or Kuberenetes, get in touch through our [Discord](https://discord.gg/XdJSZyejJU). We'd love to help. #### I'm getting an "externally managed environment" error. This error usually occurs when trying to install a Python package outside of a virtual environment. To resolve this error follow the instructions on the [setting-up-a-virtual-environment](https://docs.trymito.io/getting-started/installing-mito/setting-up-a-virtual-environment "mention"). #### I do not have Python installed. Follow this [Guide to downloading Python](https://wiki.python.org/moin/BeginnersGuide/Download). {% hint style="info" %} Still having installation issues?
