Python 3-如何告诉Pipenv使用python 3而不是python 2？

Question

我正在尝试使用请求模块，这是我的安装方式：

[ec2-user@ip-xxx-xx-xx-xxx newslookup]$ pipenv install requests
Creating a virtualenv for this project...
Pipfile: /var/www/html/newslookup/Pipfile
Using /usr/bin/python2 (2.7.14) to create virtualenv...

To activate this project's virtualenv, run pipenv shell.
Alternatively, run a command inside the virtualenv with pipenv run.

这是我运行脚本时的样子：

[ec2-user@ip-xxx-xx-xx-xxx newslookup]$ python3 nasdaq_scrape_sec.py
Traceback (most recent call last):
  File "nasdaq_scrape_sec.py", line 5, in <module>
    import requests
ModuleNotFoundError: No module named 'requests'

如您所见，问题是当我安装它时，它使用的是python 2而不是python 3 (Using /usr/bin/python2 (2.7.14))

如何告诉Pipenv使用Python 3而不是Python 2？

还是有安装请求的特定python 3方法？

Answer 1

您可以将以下几行添加到pip文件中：

[requires]
python_version = "3.6"

或运行（假设您已经在计算机上安装了Python 3.6）：

pipenv --python 3.6

Answer 2

创建环境时，Pipenv 会自动扫描您的系统以查找与给定版本匹配的 Python。

pipenv --python VERSION
