python-2.7 - pipenv：TypeError：强制转换为 Unicode：需要字符串或缓冲区，找到类型

问题描述

我正在尝试使用 pipenv 在我的项目存储库中安装 pyspark 2.4.0。我正在尝试创建一个 virtualenv 以避免库版本与其他各种项目发生冲突。

在 Ubuntu 14.04 中运行以下命令

pipenv install pyspark==2.4.0

pipenv 以：

Pipfile: /path/to/Pipfile

Traceback 看起来像这样：

pipenv 无法安装 pyspark 版本：TypeError: coercing to Unicode: need string or buffer, type found

pipenv version: 2018.10.13
python version: 2.7.12

解决方案

对我来说，问题是我在保存所有项目的父目录中创建了一个 virtualenv。所以我有一种嵌套的 virtualenv 情况。删除与父目录对应的 /.local/share/virtualenv 中的 virtualenv 文件夹为我解决了这个问题。
