<p>ubuntu 14.04</p>
<p>Python で、selenium ChromeDriver を起動しようとして</p>
<pre>$ xvfb-run ipython</pre>

<p></p>
<p>となったら。</p>
<p></p>
<p>まず、chromedriver 単体で起動してみる</p>
<pre>$ chromedriver<br />chromedriver: error while loading shared libraries: libgconf-2.so.4: cannot open shared object file: No such file or directory</pre>
<p>&rarr; 起動失敗</p>
<p></p>
<p>libgconf2 をインストール</p>
<pre>$ apt search libgconf<br /><br />...<br /><br />$ sudo apt install libgconf2-4</pre>
<p></p>
<p>chromedriver を再実行してみる</p>
<pre>$ chromedriver<br />Starting ChromeDriver 2.29.461571 (8a88bbe0775e2a23afda0ceaf2ef7ee74e822cc5) on port 9515<br />Only local connections are allowed.</pre>
<p>起動した!</p>
<p></p>
<p>再度Python から実行</p>
<pre>$ xvfb-run ipython</pre>
<pre>In [1]: from selenium.webdriver import Chrome<br /><br />In [2]: d = Chrome()<br /><br />In [3]:</pre>
<p>&nbsp;起動した!</p>
