python - Pipenv 安装运行时错误 : location not created nor specified

Question

我正在使用 Pipenv 来管理项目依赖项。到目前为止，它运行良好。现在我正在尝试使用 pipenv install 引导环境我收到以下错误:

❯ pipenv install --dev --skip-lock

Pipfile 如下

python_version = "3.7"

我已经用 Homebrew 安装了 Pipenv。我不确定会发生什么变化以停止工作。其他较旧的项目继续工作，但每次我尝试创建环境时都会出现此错误。

谢谢!

Answer 1

所以我设法让它工作。我的默认 python 系统安装是 3.7.3 .但是，由于某种原因，pipenv 不喜欢那个。我安装了python 3.7.7使用 Homebrew 软件和 pipenv 能够正确定位该版本并使用它来创建虚拟环境。

总之，要解决此问题，请尝试再次安装 python。就我而言:

brew install python
