Preparing for installation on Ubuntu¶

Python and basic development tools

sudo apt-get install python3-dev gcc cython python-virtualenv

Additional necessary packages for a Reahl installation
```
sudo apt-get install libxml2-dev libxslt-dev zlib1g-dev libsqlite3-0
```
The next step is to create a virtualenv.
Chromedriver (optional)

You do not need to install chromedriver in order to follow this tutorial. However, if you are going to use chromium for testing, you will need chromedriver.
```
sudo apt-get install chromium-chromedriver
```
You also need to adjust your PATH so that /usr/lib/chromium-browser is included. In your .bashrc, add the line:
```
export PATH=$PATH:/usr/lib/chromium-browser
```
Note

In Ubuntu 14.4, the chromedriver binary is installed in /usr/lib/chromium-browser/chromedriver, but it neglects setting the LD_LIBRARY_PATH for it to work correctly. To correct this, create the file /etc/ld.so.conf.d/chrome_lib.conf, with the following contents:
```
/usr/lib/chromium-browser/libs
```
Finally, run:
```
sudo ldconfig
```
