Selenium使用Python - Geckodriver可执行文件需要在PATH中

我正在用Python文本阅读Sweigart的《自动化无聊的东西》。我正在使用IDLE，并且已经安装了Selenium模块和Firefox浏览器。

每当我试图运行webdriver函数，我得到这个:

from selenium import webdriver
browser = webdriver.Firefox()

例外:

Exception ignored in: <bound method Service.__del__ of <selenium.webdriver.firefox.service.Service object at 0x00000249C0DA1080>>
Traceback (most recent call last):
  File "C:\Python\Python35\lib\site-packages\selenium\webdriver\common\service.py", line 163, in __del__
    self.stop()
  File "C:\Python\Python35\lib\site-packages\selenium\webdriver\common\service.py", line 135, in stop
    if self.process is None:
AttributeError: 'Service' object has no attribute 'process'

    if self.process is None:
AttributeError: 'Service' object has no attribute 'process'

    stdout=self.log_file, stderr=self.log_file)
  File "C:\Python\Python35\lib\subprocess.py", line 947, in __init__
    restore_signals, start_new_session)
  File "C:\Python\Python35\lib\subprocess.py", line 1224, in _execute_child
    startupinfo)
FileNotFoundError: [WinError 2] The system cannot find the file specified

在处理上述异常时，发生了另一个异常:

Traceback (most recent call last):
  File "<pyshell#11>", line 1, in <module>
    browser = webdriver.Firefox()
  File "C:\Python\Python35\lib\site-packages\selenium\webdriver\firefox\webdriver.py", line 135, in __init__
    self.service.start()
  File "C:\Python\Python35\lib\site-packages\selenium\webdriver\common\service.py", line 71, in start
    os.path.basename(self.path), self.start_error_message)
selenium.common.exceptions.WebDriverException: Message: 'geckodriver' executable needs to be in PATH.

我想我需要为geckodriver设置路径，但我不确定如何，所以我该如何做到这一点?

当前回答

Selenium在他们的描述中回答了这个问题。rst文件:

司机 = = = = = = = Selenium需要一个驱动程序来与所选的浏览器交互。Firefox, 例如，需要geckodriver <https://github.com/mozilla/geckodriver/releases>_，在运行下面的示例之前需要安装它。确保它在你的PATH中，例如，将它放在/usr/bin或/usr/local/bin中。

如果没有注意到这一步，将会出现一个错误:selenium.common.exceptions.WebDriverException: Message: 'geckodriver'可执行文件需要在PATH中。

基本上只需要下载geckodriver，解包并将可执行文件移动到/usr/bin文件夹。

其他回答

这个步骤在Ubuntu和Firefox 50上为我解决了这个问题。

下载geckodriver 拷贝geckodriver到/usr/local/bin文件夹

不需要添加:

firefox_capabilities = DesiredCapabilities.FIREFOX
firefox_capabilities['marionette'] = True
firefox_capabilities['binary'] = '/usr/bin/firefox'
browser = webdriver.Firefox(capabilities=firefox_capabilities)

如果你正在使用Anaconda，你所要做的就是激活你的虚拟环境，然后使用以下命令安装geckodriver:

    conda install -c conda-forge geckodriver

默认不安装Geckodriver。

geckodriver

输出:

Command 'geckodriver' not found, but it can be installed with:

sudo apt install firefox-geckodriver

下面的命令不仅安装它，而且还将它放在可执行PATH中。

sudo apt install firefox-geckodriver

这个问题只需要一步就解决了。我和你有完全一样的错误，我一安装它就消失了。去吧，试一试。

which geckodriver

输出:

/usr/bin/geckodriver

geckodriver

输出:

1337    geckodriver    INFO    Listening on 127.0.0.1:4444
^C

Windows用户

使用原始代码，因为它是:

from selenium import webdriver
browser = webdriver.Firefox()
driver.get("https://www.google.com")

然后从mozilla/geckodriver下载驱动

把它放在一个固定的路径(永久地)…作为一个例子，我把它放在:

C: \ Python35

然后进入系统的环境变量。在“系统变量”网格中寻找Path变量并添加:

; C: Python35喝geckodriver

Geckodriver，不是Geckodriver .exe。

在Ubuntu上手动安装geckodriver

访问https://github.com/mozilla/geckodriver/releases 下载最新版本“geckodriver-vX.XX.X-linux64.tar.gz” 解压缩tar -xvzf geckodriver-vX.XX.X-linux64.tar.gz 给geckodriver可执行权限(chmod +x geckodriver) 将geckodriver二进制文件移动到/usr/local/bin或系统路径上的任何位置。

Ubuntu上安装geckodriver的脚本:

#!/bin/bash

INSTALL_DIR="/usr/local/bin"

json=$(curl -s https://api.github.com/repos/mozilla/geckodriver/releases/latest)
url=$(echo "$json" | jq -r '.assets[].browser_download_url | select(contains("linux64"))')
curl -s -L "$url" | tar -xz
chmod +x geckodriver
sudo mv geckodriver "$INSTALL_DIR"
echo "installed geckodriver binary in $INSTALL_DIR"

这个答案完全抄袭自: Corey Goldberg对如何在Ubuntu中安装geckodriver的回答?
