Question

我最近正在清洁计算机。删除了vstudio2017。

现在我的环境

python3.6，win10

发生了奇怪的事情，pipenv似乎完全无效。

PS F:\hankspace\flaskproject> pipenv install
Pipfile.lock not found, creating…
Locking [dev-packages] dependencies…
Locking [packages] dependencies…
Locking Failed!
Traceback (most recent call last):
  File "c:/users/hank/appdata/local/programs/python/python37/lib/site-packages/pipenv/resolver.py", line 3, in <module>
    import json
ModuleNotFoundError: No module named 'json'
File "c:/users/hank/appdata/local/programs/python/python37/lib/site-packages/pipenv/resolver.py", line 3, in <module>
    import json
ModuleNotFoundError: No module named 'json'

除了重新加载python3.7和pipenv外，我还删除了python3.6和pipenv。但是他们有同样的问题。

PS F:\hankspace\flaskproject> pipenv graph

ERROR:  Traceback (most recent call last):
  File "c:\\users\\hank\\appdata\\local\\programs\\python\\python37\\lib\\site-packages\\pipenv\\vendor\\pipdeptree.py", line 6, in <module>
    import argparse
ModuleNotFoundError: No module named 'argparse'

我列出了我尝试过的内容。

$ pip install --user pipenv
删除的点数重新加载点数
导出路径

这是一个非常像我的例子。Python sees json module but pipenv doesn't. Why?

我想他也许已经解决了问题，但是我没有足够的声誉发表评论。如果有人能给我一些建议，我将不胜感激。

Answer 1

为我解决的问题是在系统环境变量中添加了以下内容：

在Windows中：

setx /M PIPENV_VENV_IN_PROJECT 1

这将强制pipenv在项目文件夹中创建一个“ .venv”目录，而不是用户配置文件目录中的默认“ virtualenvs”（这是打破“ pipenv安装”的部分）。它还将为您提供与pipenv创建它的方式相对应的正确“ .venv”目录和文件结构，而不是“ python -m venv .venv”创建它的方式。从我所看到的，结构是不同的。

有关此问题的更多信息，请参见以下URL： https://github.com/pypa/pipenv/issues/1382

如果要在Linux中获得相同的结果，请使用以下命令设置变量：

export PIPENV_VENV_IN_PROJECT=1

Answer 2

基于共享的命令和回溯，您是否实际上创建并进入了环境？（pipenv外壳）

我遇到了类似的问题，即安装软件包后无法锁定，结果发现我安装了64位和32位Python，这引起了冲突。为了解决这个问题，我删除了32位（“开始”菜单->“设置”->“应用”），然后删除了已经创建的虚拟环境。导航到C：\ Users \ .virtualenvs，然后删除具有您的环境名称的文件夹。现在，您可以导航到您的文件夹，并通过调用pipenv shell再次创建pipenv环境。

感谢布莱恩， bryan提醒我，当我选择一个新文件夹并运行 pipen shell

Failed to create virtual environment.

然后我发现这个问题可以追溯到virtualenv，最后我发现这篇帖子https://itqna.net/questions/16455/problems-trying-create-virtual-environment-pipenv解决了我的问题

python -m venv .venv 
pipenv shell
pipenv install

成功了！

Answer 4

尝试以下命令：

python36ana.exe -m pipenv --python 3.6

Pipenv安装锁定失败！没有名为“ json”的模块
