有 python 2.7,但没有 python3.6
跑步时,
$ python functionalTest.py
它工作正常
但
$ python3.6 functionalTest.py
给出错误:
ModuleNotFoundError: No module named 'selenium'
因为我无法在 Ubuntu 上使用 python3.6 安装 selenium,所以成功了,如下所示,
$ ls setup*
setup.cfg setup.py
$ python3.6 setup install
python3.6: can't open file 'setup': [Errno 2] No such file or directory
$ python3.6 setup.py install
Traceback (most recent call last):

Original exception was:
Traceback (most recent call last):

from setuptools import setup
ModuleNotFoundError: No module named 'setuptools'

安装后setuptools

问题:
1)为什么要在中安装 selenium、easy_install 和 pip /usr/local/lib/python2.7/dist-packages
?我需要在中安装这些包/usr/local/lib/python3.6/dist-packages
。
2)如何配置python3.6来选择selenium?
3)为什么python --version
不显示蟒蛇3.6除非明确询问python3.6 --version
?
答案1
- 给定包的名称(selenium-3.4.3-py2.7.egg) 这是适用于 Python 2.7 的包。查找适用于 Python 3.6 的包。
- 安装适合 Python 3.6 的软件包
- 因为大多数 Linux 发行版默认
python
仍然是 2.7,因为有很多脚本是为 2.7 编写的
在我的 Ubuntu 16.04上,python3
来自存储库的软件包是 Python 3.5.3 ( sudo apt install python3
)。 也可以从存储库安装 Selenium ( sudo apt install python3-selenium
)。
