ImportError: No module named 'selenium'
提问by Giulio Colleluori
I'm trying to write a script to check a website. It's the first time I'm using selenium. I'm trying to run the script on a OSX system. Although I checked in /Library/Python/2.7/site-packages and selenium-2.46.0-py2.7.egg is present, when I run the script it keeps telling me that there is no selenium module to import.
我正在尝试编写脚本来检查网站。这是我第一次使用硒。我正在尝试在 OSX 系统上运行脚本。尽管我检查了 /Library/Python/2.7/site-packages 并且 selenium-2.46.0-py2.7.egg 存在，但当我运行脚本时，它一直告诉我没有要导入的 selenium 模块。
This is the log that I get when I run my code:
这是我运行代码时得到的日志：
Traceback (most recent call last): File "/Users/GiulioColleluori/Desktop/Class_Checker.py", line 10, in <module> from selenium import webdriver ImportError: No module named 'selenium'

If you have pip installed you can install selenium like so.
如果你安装了 pip，你可以像这样安装 selenium。
pip install selenium
pip install selenium
or depending on your permissions:
或根据您的权限：
sudo pip install selenium
sudo pip install selenium
As you can see from this question pip vs easy_installpip is a more reliable package installer as it was built to improve easy_install.
从这个问题中可以看出pip vs easy_installpip 是一个更可靠的包安装程序，因为它是为了改进 easy_install 而构建的。
I would also suggest that when creating new projects you do so in virtual environments, even a simple selenium project. You can read more about virtual environments here. In fact pip is included out of the box with virtualenv!
我还建议在创建新项目时在虚拟环境中进行，即使是一个简单的 selenium 项目。您可以在此处阅读有关虚拟环境的更多信息。事实上，pip 已经包含在 virtualenv 中！

Even though the egg file may be present, that does not necessarily mean that it is installed. Check out this previous answer for some hint:
即使可能存在 egg 文件，也不一定意味着它已安装。查看之前的答案以获得一些提示：

first you should be sure that selenium is installed in your system.
首先，您应该确保系统中安装了 selenium。

然后安装 pycharm https://itsfoss.com/install-pycharm-ubuntu/
now if an of packages are not installed it will show red underlines. click on it and install from pycharm.
现在如果没有安装软件包，它将显示红色下划线。单击它并从 pycharm 安装。
like for this case click on selenium option in import statement, there you would getting some options. click on install selenium. it will install and automatically run the code successfully if all your drivers are placed in proper directories.
就像在这种情况下单击导入语句中的 selenium 选项一样，您将获得一些选项。点击安装硒。如果您的所有驱动程序都放在正确的目录中，它将成功安装并自动运行代码。

Your IDE might be pointing to a different installation of Python than where Selenium is installed.
您的 IDE 可能指向与安装 Selenium 的位置不同的 Python 安装。
I'm using Eclipse and when I ran 'quick auto-configure' under:
我正在使用 Eclipse，当我在下面运行“快速自动配置”时：
Preferences > PyDev > Interpreters > Python Interpreter
首选项 > PyDev > 解释器 > Python 解释器
it pointed to a different version of Python than where pip or easy_install actually installed it.
它指向的 Python 版本与 pip 或 easy_install 实际安装它的位置不同。
Selenium worked from the Terminal so I determined which version of python my Terminal was using by running this:
Selenium 在终端上工作，所以我通过运行以下命令来确定我的终端使用的是哪个版本的 python：
python -c "import sys; print(sys.path)"
then had Eclipse point to that same location, which for me on my 10.11 Mac was here:
然后让 Eclipse 指向同一个位置，对我来说，在我的 10.11 Mac 上是这样的：
/Library/Frameworks/Python.framework/Versions/Current/bin/python2.7/
/Library/Frameworks/Python.framework/Versions/Current/bin/python2.7/
You can run "Advanced Auto-Config" as well to see all of the installed versions of python and select the one you want to use. When I selected that same location using "Advanced Auto-Config" it finally showed me the Selenium folder as it went through the configuration steps.
您也可以运行“高级自动配置”来查看所有已安装的 Python 版本并选择您要使用的版本。当我使用“高级自动配置”选择相同的位置时，它最终向我展示了 Selenium 文件夹，因为它完成了配置步骤。

Navigate to your scripts folder in Python directory (C:\Python27\Scripts) and open command line there (Hold shift and right click then select open command window here). Run pip install -U selenium
If you don't have pip installed, go ahead and install pip first
导航到 Python 目录 (C:\Python27\Scripts) 中的脚本文件夹并在那里打开命令行（按住 shift 并右键单击，然后选择在此处打开命令窗口）。运行pip install -U selenium
如果您没有安装 pip，请先安装 pip
