我对此完全陌生。所以我使用“ pip install pipenv”安装了pipenv。我有python版本3.8.2，pip版本20.1.1和pipenv版本2020.6.2。 但是，当我尝试运行“ pipenv install”时，出现以下错误。

Python位置：'D:\\python382\\python.exe'
找到了Python安装：
再次出现相同的错误。
我在'D：/ python382'中安装了python 没有错误提及的目录。我检查了我的环境变量，那里的一切也都很好。请帮助我解决此错误。
谢谢您的时间。

我认为较新版本的 pipenv 导致了错误，我在遇到相同问题时使用此命令并且对我有用，只需使用
pip install pipenv==2018.10.13
答案 1 :(得分：1)
您需要提供piplock文件或require.txt才能安装软件包
答案 2 :(得分：1)
我在卸载 Anaconda 时遇到了同样的问题。我按照以下步骤解决了
运行 regedit.exe
前往
计算机\HKEY_CURRENT_USER\Software\Python\PythonCore
答案 3 :(得分：0)
您是否尝试过conda install命令？为此，请在安装anaconda的文件夹中继续显示anaconda提示符cd。看看this。
conda install -c conda-forge pipenv
确保在运行conda install命令之前激活环境。要激活您的环境，请运行conda activate envname。希望对您有所帮助！

我只是在与pipenv遇到类似的问题，该问题也给了我相同的错误消息。
WinError 2与您的一个Python安装/卸载中的损坏文件有关。我在regedit中搜索了Anaconda3，以确定我以前安装或卸载的哪个版本的Python引起了问题。
对我来说，它是Python 3.6.5。我将其安装在错误消息中的路径所在的位置（在您的情况下为D:/program_files/）。然后，我只是使用安装exe卸载了它，然后停止获取这些错误消息。
