标签: pipenv

我正在学习Python.在我的一个小项目中,我跑了

pipenv run python myproject.py

它为我创造了一个虚拟的东西 C:\Users\USERNAME\.virtualenvs

我发现它还在我的项目源代码目录下创建或修改了一些文件.我只是想知道如何干净地删除这个virtualenv并将我的项目反转回no-virtualenv状态.

我使用的是python 3.6.4和PyCharm.

我是Python开发新手并试图使用pipenv.我运行了pip install pipenv成功运行的命令:

...
Successfully built pipenv pathlib shutilwhich pythonz-bd virtualenv-clone
Installing collected packages: virtualenv, pathlib, shutilwhich, backports.shutil-get-terminal-size, pythonz-bd, virtualenv-clone, pew, first, six, click, pip-tools, certifi, chardet, idna, urllib3, requests, pipenv
...

但是,当我pipenv install在一个新的根项目目录中运行该命令时,我收到以下消息:-bash: pipenv: command not found.我怀疑我可能需要修改我的.bashrc,但我不清楚要添加到文件中的内容或者是否需要进行修改.

有没有办法在Jupyter笔记本上使用pipenv？

或者更具体地说,使用原子nteract /氢python 3内核？

我重新安装了pip和pipenv,因为有一些破损的包装与ansible.现在,似乎我的pip依赖都被搞砸了.非常感谢任何建议或帮助.

$ which python2
 /usr/local/bin/python2

$ which python3
/usr/local/bin/python3

$ which pipenv
/usr/local/bin/pipenv

我尝试在新环境中执行pipenv shell，但出现以下错误：

Loading .env environment variables\xe2\x80\xa6\nCreating a virtualenv for this project\xe2\x80\xa6\nUsing /home/user/.pyenv/shims/python3.9 (3.9.7) to create virtualenv\xe2\x80\xa6\n\xe2\xa0\x8bModuleNotFoundError: No module named 'virtualenv.activation.xonsh'\nError while trying to remove the /home/user/.local/share/virtualenvs/7t env: \nNo such file or directory\n\nVirtualenv location: \nWarning: Your Pipfile requires python_version 3.9, but you are using None (/bin/python).\n  $ pipenv check will surely fail.\nSpawning environment shell (/usr/bin/zsh).

我尝试删除 pipelinenv，使用 pienv 安装 python 创建 python 的别名，但一切正常。

无论如何，我在现有环境中遇到了同样的错误，我尝试删除所有环境文件夹，但什么也没删除。

谢谢。

当两个开发人员正在处理具有不同操作系统的项目时,它们Pipfile.lock是不同的(特别是内部部分host-environment-markers).

对于PHP,大多数人建议提交composer.lock文件.

我们是否必须为Python做同样的事情？

我在我的码头工人安装pipenv:

RUN pip install pipenv
RUN cd /my/app/path/ && pipenv install
RUN cd /my/app/path/ && pipenv shell

我得到错误:

我的Ubuntu 16.04.03安装了Python 3.5.2.当我的系统没有python 3.6时,如何设置pipenv以使用Python 3.6？

$ pipenv --python 3.6
Warning: Python 3.6 was not found on your system…
You can specify specific versions of Python with:
  $ pipenv --python path/to/python

安装 [numpy|opencv|pandas] 时，为什么我的 pipenv 卡在“锁定...”阶段？

运行时pipenv install pandas或pipenv update挂起很长时间，并显示一条消息和加载屏幕，表明它仍在锁定。为什么？我需要做什么？

我开始尝试获得一个工作的pipenv,但是在我的Mac上,似乎我的Python环境有点搞砸了.我在这篇文章之后删除了OS X python ,并使用brew安装了python2.7和python3.7.但是现在当尝试使用pipenv(2.7)来创建virtualenv和pipfile时,我在锁定pacakges时不断收到有关python 3.7的错误:

我重新安装了PIP和python几次,没有运气.任何想法将不胜感激.我肯定通过python可能只是在一些糟糕的状态:(
