Pipenv 安装锁定失败！没有名为 'json' 的模块

Question

我正在清理我的电脑recently.I删除了vstudio2017.

现在我的环境

python3.6,win10

奇怪的事情发生了，pipenv好像完全失效了

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'

我删除了 python3.6 和 pipenv，另外重新加载 python3.7 和 pipenv。但他们有同样的问题。

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'

我列出了我提交的尝试。

$ pip install --user pipenv
已删除 pip 重新加载 pip
导出路径

这是一个看起来很像我的例子。Python sees json module but pipenv doesn't. Why?

我想他可能已经解决了问题，但我没有足够的声誉来发表评论。如果有人能给我一些建议，我将不胜感激。

Answer 1

根据您分享的命令和回溯，您是否真的创建并进入了您的环境？ (pipenv shell)

我运行遇到了类似的问题，它在安装软件包后无法锁定，结果我安装了 64 位和 32 位 Python，这导致了冲突。为了修复它，我删除了 32 位（开始菜单 -> 设置 -> 应用程序），然后删除了我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。现在您可以导航回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和运行 pipenv shell

Failed to create virtual environment.

然后我发现这个问题可以追溯到virtualenv，最后我发现这个post 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 3

尝试以下命令：

python36ana.exe -m pipenv --python 3.6

Answer 4

为我修复的是将以下内容添加到我的系统环境变量中：

在Windows中：

setx /M PIPENV_VENV_IN_PROJECT 1

这将强制 pipenv 在您的项目文件夹中创建一个“.venv”目录，而不是在您的用户配置文件目录中创建默认的 "virtualenvs"（这部分是破坏性的 "pipenv install"）。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。据我所见，结构不同。

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

如果您想要在 Linux 中得到相同的结果，请使用以下命令设置变量：

export PIPENV_VENV_IN_PROJECT=1
