使用命令安装 pipenv

sudo apt install python3-pipenv

我尝试使用 Python 版本运行:在文件.env和命令行参数中 - 重复了这个结果。在 StaсkOverflow 上有一个类似的问题,但解决方案不适合我。我对语言环境没有问题。

这是一个老问题,但也许这可以帮助像我一样遇到这个问题的人:

我可以通过使用来避免这个问题python3 -m pipenv

在我的情况下,没有安装 Python 2,pythonPATH 中也没有可执行文件。为了解决这个问题,我创建了一个符号链接:

# find location of python3
$ which python3
/usr/bin/python3

# create link from python to python3 in the original directory
$ ln -s /usr/bin/python3 /usr/bin/python
