PermissionError:[Errno 13]权限被拒绝:Pipenv安装请求的"Pipfile" [英] PermissionError: [Errno 13] Permission denied: 'Pipfile' for pipenv install requests

问题描述

我正在尝试在pipenv和virtualenv上遵循此指南: http ://docs.python-guide.org/en/latest/dev/virtualenvs/.问题是，尝试$ pipenv install requests时遇到问题(我认为应该是$python3 -m pipenv install requests，因为简单地pipenv返回未找到的命令.)

I'm trying to follow this guide on pipenv and virtualenv: http://docs.python-guide.org/en/latest/dev/virtualenvs/ . The problem is, I run into a problem when trying to $ pipenv install requests (which in my case I think should be $python3 -m pipenv install requests since simply pipenv returns command not found.)

为什么拒绝权限?

我是终端新手，请多多包涵.

I'm a terminal noob so bear with me.

$ pip3 install --user pipenv

$ python3 -m pipenv

Usage: __main__.py [OPTIONS] COMMAND [ARGS]...

$ python3 -m pipenv install requests

推荐答案

确保已添加

Make sure you've added the UserBase's bin directory to your path (follow the Note box at the documentation you were following to see how to do this).

您提到的第三个命令应该是:pipenv install requests.

The third command you mentioned should just be: pipenv install requests.

长版:

自从您开始使用命令行(以及其他想要更深入参考的人)以来，我将对一些命令行概念进行更深入的介绍.

I'll go a little more in depth for some of the command line concepts since you're getting started with the command line (and for others who would like a little more in depth reference).

您显示三个命令:

• pip3 install --user pipenv
• 这很完美，它将 pipenv 作为用户软件包安装(不适用于整个系统)
• python3 -m pipenv
• 这什么也没做.您看到的返回的是"用法消息".也就是说，此命令需要一些main.py程序，选项(由于括号是可选的)，命令(强制性)和可能更多的参数.如果您看到使用情况消息，则表示您没有按照作者的意图调用该程序.
• python3 -m pipenv install requests
• 这应该只是pipenv install requests.但是，直到您将UserBase的bin添加到路径中(您会收到pipenv: command not found错误)，它才起作用.

• pip3 install --user pipenv
• This is perfect, it installs pipenv as a user package (not avalible to the entire system)
• python3 -m pipenv
• This doesn't do anything. What you see returned is a "Usage message". It's saying this command expects some main.py program, options (optional because in parenthesis), a command (mandatory) and potentially more arguments. If you see a usage message it means you did not call that program the way its author intended.
• python3 -m pipenv install requests
• This should just be pipenv install requests. But it won't work until you've added UserBase's bin to your path (you'll get a pipenv: command not found error).

您的 PATH 是您的shell搜索您列出的命令的地方.请在 Mac或Linux 或<一个href ="http://windowsitpro.com/systems-management/how-can-i-add-new-folder-my-system-path" rel ="nofollow noreferrer"> Windows .

作为文档，您正在关注以下内容: ，您要运行python3 -m site，将得到类似以下内容的输出:

As the documentation you were following mentions, you want to run python3 -m site, you'll get output something like the following:

$ python -m site
  .
  .
  .
USER_BASE: '/Users/<myusername>/Library/Python/3.6' (exists)
USER_SITE: '/Users/<myusername>/Library/Python/3.6/lib/python/site-packages' (exists)
ENABLE_USER_SITE: True

现在您知道USER_BASE的位置了，在末尾添加/bin并将其添加到PATH中.再次查看特定于操作系统的说明，但是在OSX上，您可以将export PATH="$PATH:/Users/<myusername>/Library/Python/3.6/bin添加到~/.profile中，运行source ~/.profile，并且当您输入命令pipenv时，shell现在将搜索该目录.

Now that you know where your USER_BASE is, add a /bin onto the end and add it to your PATH. Again see OS specific instructions but on OSX you can add export PATH="$PATH:/Users/<myusername>/Library/Python/3.6/bin to your ~/.profile, run source ~/.profile, and your shell will now search that directory when you enter the command pipenv.
