python - 如何检查Selenium2library是否已添加到RIDE中的robotframework项目中

我对机器人框架很陌生
我正在使用RIDE 1.5.2.1在Python 2.7.13上运行。
在我的机器上安装了Python之后，我执行了以下步骤来安装selenium2库：

python -m pip install robotframework-selenium2library

似乎已经安装到路径上了：

C:\Python27\Lib\site-packages

现在，我想在RIDE中将selenium2库添加到我的robotframework项目中，但找不到该文件。
下面是我的测试套件：

*** Settings ***
Library           selenium2library

*** Test Cases ***
User can load the landing page
    [Documentation]    User opens the landing page
    Open Browser    http://localhost:8080/    ie
    Close Browser

但它失败了，出现了以下错误：

[ ERROR ] Error in file 'C:\Python27\Scripts\Customer\Landing_Page\Landing_Page.txt': Importing test library 'selenium2library' failed: ImportError: No module named selenium2library
Traceback (most recent call last):

    1 critical test, 0 passed, 1 failed
    1 test total, 0 passed, 1 failed

它似乎找不到selenium2库，但当我再次尝试安装它时，它说：

Requirement already satisfied: robotframework-selenium2library in c:\pytho
b\site-packages
Requirement already satisfied: decorator>=3.3.2 in c:\python27\lib\site-pa
 (from robotframework-selenium2library)
Requirement already satisfied: selenium>=2.32.0 in c:\python27\lib\site-pa
 (from robotframework-selenium2library)
Requirement already satisfied: robotframework>=2.6.0 in c:\python27\lib\si
kages\robotframework-3.0-py2.7.egg (from robotframework-selenium2library)

？

最佳答案

请按照本网站上的说明操作
https://github.com/robotframework/RIDE/wiki/Installation-Instructions
一旦您将其与PIP一起安装-https://github.com/robotframework/robotframework/blob/master/INSTALL.rst#installing-with-pip
可以使用“pip freeze”命令检查库的安装版本
还要确保使用python安装的文件夹和脚本文件夹更新PATH变量
一旦您知道安装了所有必需的库，就可以导入selenium库
