chromedriverが起動していないのでは？と思い、以下のコマンドで確認したところ、9515番portは起動していませんでした。
|
|
192
|
+
`netstat -atn|grep LISTEN`
|
|
193
|
+
```
|
|
194
|
+
tcp6 0 0 ::1.3000 *.* LISTEN

##chromeのversionを合わせる
|
|
207
|
+
`ChromeDriver`を`Google Chrome`のバージョンに合わせてみようとしましたが、`ChromeDriver 75.0.3770.100`が見つかりませんでした。
|
|
208
|
+
- ChromeDriver 75.0.3770.90
|
|
209
|
+
- Google Chrome 75.0.3770.100
|
|
210
