------------------------------------- 这是用PyCharm 安装时的报错 ------------------------------------------

PyCharm Project Interpreter 中也未检测到 dotenv
求各位大神指导，dotenv改如何安装？

请把命令行文本或代码用代码块格式化一下。

插入代码块的方式：除了将所有代码缩进四格，更方便的插入代码块方式是使用三个连续的反引号作为开始和结束标记，比如：

```
def hello():
return ‘Hello World’
```

会被渲染为：

 def hello():
     return 'Hello World'

具体参考论坛说明。

看了下 https://pypi.org/project/python-dotenv/ pipenv支持的Python的版本，没有3.7。要不你用回Python36试试

Python太新了。

greyli · 2019 年4 月 24 日 13:42

$ pipenv install python-dotenv

注意拼写。

另外，请参考上上条回复改进你的正文。

想起来了！dotenv正确安装命令是

pip install python-dotenv

安装包名称是python-dotenv不是dotenv。

谢谢大神指导，但是还是没解决啊:
我把python降级到3.6.7了，也在全局安装了 python-dotenv，按时在虚拟环境中安装的时候，安装到时安装成功了，但是提示无法锁定：

pipenv uninstall python-dotenv之后再重新安装试一下
