是否可以一次升级所有Python包pip？

请注意,官方问题跟踪器上有此功能请求.

当我跑:

sudo pip install ipython

我收到以下错误

OSError:[Errno:1]不允许操作:'/System/Library/Frameworks/Python.framework/Versions/2.7/share'

执行的最后一个命令尝试创建上面给出的目录.

此外,以下命令无法在不提供任何错误的情况下安装iPython.

sudo pip install --user python

(我在Mac OS X El Capitan上,以防此操作系统上的其他人看到同样的问题.)

在我的macOS Mojave终端中,我想用pip安装一个python包.它有效,但它说:

You are using pip version 10.0.1, however version 18.1 is available.
You should consider upgrading via the 'pip install --upgrade pip' command.

所以我想用给定的命令更新pip,但是我收到一个错误:

Could not install packages due to an EnvironmentError: [Errno 13] Permission denied: 
'/Library/Python/2.7/site-packages/pip-18.0-py2.7.egg/EGG-INFO/PKG-INFO'
Consider using the `--user` option or check the permissions.

这个东西可以滚动 - - - - - >

我真的不明白现在该做什么.此外,我意识到它在错误消息中说Python 2.7,但我有并且只想使用python 3.

我安装了所有依赖项的opencv.安装完成后,我尝试导入matplotlib作为一个简单的例子.

然后我得到以下错误,当我尝试通过pip安装matplotlib时pip install matplotlib:

Could not install packages due to an EnvironmentError: [Errno 13] Permission denied: '/usr/local/lib/python3.5/dist-packages/kiwisolver.cpython-35m-x86_64-linux-gnu.so'
Consider using the `--user` option or check the permissions.

我该怎么做才能安装matplotlib？

我不能在Ubuntu上安装基本的Django包.我刚刚删除了virtualenv并重新制作了它.pip3install=pip3 install -r requirements.txt

上面的错误是我尝试使用pip命令时得到的错误.我需要做的就是pip安装requirements.txt以使我的程序正常工作.我安装了python 2.7.1并将我的代码放在我可以使用python命令的地方.我尝试使用此命令更改权限:

chmod -R 777

但它不起作用.我在我的电脑上安装了自制软件.我还尝试使用这个链接使用虚拟环境:http: //sourabhbajaj.com/mac-setup/Python/virtualenv.html但它也给了我许可问题.有没有建议摆脱这个权限问题并成功运行pip？下面的sudo命令也不起作用.

sudo pip install -r requirements.txt

我目前正在 Ubuntu 18.04 LTS 上构建一个使用 Python、Flask、Docker、Docker-compose 和 Postgres 的应用程序。以前，docker-compose 构建会成功，一切都按计划进行。但是，现在我切换到另一个 Dockerfile，并且不再使用先前 Dockerfile 的缓存版本，构建会中断并出现以下错误：

PermissionError: [Errno 13] Permission denied: '/usr/lib/python3.7/__pycache__/__future__.cpython-37.pyc.140409285875056'
dpkg: error processing package python3.7-minimal (--configure):
 installed python3.7-minimal package post-installation script subprocess returned error exit status 1
Errors were encountered while processing:
 python3.7-minimal

我尝试过以下（Stackoverflow）帖子：

• 安装 Django 时出现“PermissionError：[Errno 13] 权限被拒绝：'/usr/lib/python3.5/site-packages'”
• docker-compose ， PermissionError：[Errno 13] 权限被拒绝：'/manage.py'
• 如何一步更改文件夹及其子文件夹/文件的权限？
• pip 安装失败，并显示：OSError: [Errno 13] 目录权限被拒绝
• docker-compose up && docker-compose build：PostgreSQL 错误
• https://phoenixnap.com/kb/fix-sub-process-usr-bin-dpkg-returned-error-code-1

但可惜，无济于事。

我正在使用以下文件：

Dockerfile.prod

# pull official base image
FROM python:3.9.0-slim-buster

# set working …

我在 Mac OS X 上，我听说为了避免可能导致 OS X 使用的 python 文件出现问题的包的全局安装（使用 sudo），安装 python 包的路径必须与 OS X 的路径不同.

目前 python 可执行文件安装在：

/usr/local/bin/

Pip 在这里安装模块：

/usr/local/lib/python2.7/site-packages

Python从这里使用：

/usr/local/bin/python

这些路径安全吗？

我试图在aws ec2实例上运行一个小的python代码(需要pytz和其他一些软件包).当我尝试安装pytz时,我遇到了一些错误:
