Question

我已经愉快地使用了pipenv几个月了，但是今天我坏了一些东西，无法解决。当我尝试让line_profiler工作时，一切就开始了。 It doesn't work with pip at the moment，所以我尝试按照自述文件中的说明进行操作。因此，此操作无效，因为我无法弄清楚如何从cython安装brew。

症状如果我创建一个新目录，并执行一个简单的命令，例如pipenv install pandas，那么一切正常，那么我将得到一个Pipfile，如下所示：

[[source]]
name = "pypi"
url = "https://pypi.org/simple"
verify_ssl = true

[dev-packages]

[packages]
pandas = "*"

[requires]
python_version = "3.7"

如果我随后将此Pipfile复制到新目录并尝试使用pipenv install在其中创建虚拟环境，它将失败，并显示以下消息：

如果我转到以前工作的目录之一，然后尝试pipenv run jupyter notebook，则会收到如下错误：

pipenv run jupyter notebook

我尝试卸载并重新安装pipenv，以及常见的技巧pipenv --rm和删除缓存~/Library/Caches/pipenv

您知道我还能检查什么，或者可能会发生什么？

Answer 1

我现在又重新开始工作了。我承认这不是一个很好的答案，但它可能会对某人有所帮助。我不确定过程的哪一部分是关键的，什么是偶然的：

我发现ssl库不适用于基本的pip。这导致我重新安装了使用pyenv安装的Python版本。 pip然后开始工作。
我卸载了brew中的pipenv版本，并使用pip install重新安装了它。

所以基本上，重新安装我所有的python工具似乎可以解决问题。

从Pipfile安装Pipenv失败，但可从命令行运行
