我无法在Docker中安装pip.

这是我的Dockerfile:

FROM ubuntu:14.04

# Install dependencies
RUN apt-get update -y
RUN apt-get install -y git curl apache2 php5 libapache2-mod-php5 php5-mcrypt php5-mysql python3.4 python-pip

建设时,我得到:

试图让我的Ubuntu电脑上的pip工作.pip似乎适用于python2.7,但不适用于其他人.

这是问题所在:

$ pip

我从Package Index> pip 1.2.1下载了pip

然后我用它安装它

sudo python3.3 setup.py install

不过,当我尝试使用pip-3.3终端抱怨时

-bash: pip-3.3: command not found

但是,pip-2.7游泳工作.

我也试过了

curl -O http://python-distribute.org/distribute_setup.py
sudo python3.3 distribute_setup.py
sudo python3.3 -m easy_install pip

但pip-3.3仍然行不通.

如何为Python 3.3安装pip？

请注意,有一个相关的线程如何使用Python 3安装pip？,但答案只是"安装分发...然后使用它来安装pip",这对我没有帮助,因为我已经尝试过它并没有用.

我有这个代码(用BS4文档编写):

  from bs4 import BeautifulSoup

当我运行脚本(使用python3)时,我收到错误:

  ImportError: No module named 'bs4'

所以安装BeatifulSoup:

  sudo pip install BeatifulSoup4

但是当我再次尝试运行脚本时,我得到了同样的错误.确实BS4安装在:

  BeautifulSoup4 in /usr/local/lib/python2.7/dist-packages

但我想安装并使用它与python3.3(因为有其他模块不使用python2.7).

我尝试过:

  virtualenv --python=/usr/bin/python2.7 /usr/bin/python3.3

然后再次安装BS4,但没有解决.

任何线索？提前致谢

我已经在pycharm中配置了virtualenv,当使用python manage.py命令时,显示错误:

E:\video course\Python\code\web_worker\MxOnline>python manage.py runserver
Traceback (most recent call last):

    "Couldn't import Django. Are you sure it's installed and "
ImportError: Couldn't import Django. Are you sure it's installed and available on your PYTHONPATH environment variable? Did you forget to activate a virtual environment?

我应该怎么解决它,我已经安装了django.

我的python程序有问题.我编写了程序来从arduino获取数据(温度)到我的raspberry pi sqlite数据库.但它在第4行(导入序列)中给出了一个错误,说"ImportError:没有名为serial的模块".我使用python3并且已经更新了pyserial.我是python中的新手,所以我犯了一些错误......

 #!/ussr/bin/python
 # -*- coding: utf-8 -*-

 import serial
 import datetime
 import sqlite3 as lite
 import sys
 import time

 ser = serial.Serial('/dev/ttyACM1', 9600, timeout=1)
 ser.open()

 count = 0

 con = lite.connect('realtime_data.db')

 try:
       while 1:
         indata = ser.readline()
         current_time = datetime.datetime.now().strftime("%Y-%m-%d %H:%M:%S")
         count = count + 1

         print (count)

         with con:
           cur = con.cursor()
           cur.execute("INSERT INTO Temperatures VALUES( ?, ?, ? )", (count, current_time, indata))
           if count > 100:

我的问题是安装模块"beautifulsoup4".在pycharm我正确安装了包,但是当我试图导入模块时,它说没有找到具有该名称的模块.我在互联网上搜索解决方案,我找到了一种方法.它说在终端使用这个命令:

"pip install beautifulsoup4"

但仍然pycharm或id le shell无法找到module.even我尝试了命令:

"pip install beautifulsoup4 --upgrade"

和终端说它已经是最新的.

我需要pip3安装一个包进行测试，但为此，我需要python3-pip. 然而，这在 travis 上并非如此。

错误日志也不是很具有描述性。

我有些困惑了。我现在无法为python35安装/升级任何软件包。我在Mac上有python27和python35（通过anaconda）。每当我想通过pip安装python软件包时，都会调用与python2配对的软件包。

转到anaconda文件夹（安装了我的python35的文件夹）：ls -al | 我得到的结果是：

-rwxrwxr-x    1 xx  staff      113 Jul 26  2016 conda-pipbuild

-rwxr-xr-x    1 xx  staff      230 Dec 17 21:40 pip3.5

在我的.bashrc文件中，我定义了：

 alias python2=/usr/bin/python2.7
 alias python=~/anaconda/bin/python3.5

当我输入python2时：

我想安装Biopython模块.所以我用了这个命令sudo apt-get install python-biopython.那会安装包.现在,如果我输入import Bio在Python中,编译器无法找到模块捐赠ImportError: no module named Bio.不安装包意味着安装模块吗？

我是 Django 新手。我正在使用 Ubuntu、Apache 和 virtualenv。我在 DigitalOcean 上运行 Ubuntu。我正在尝试同时使用 Django 和 React。所以我下载了djangorestframework。但是当我运行服务器时，我遇到了这个问题。

目前正在使用Cloud9ACE IDE开发环境获得一些学习机会,但是,我遇到了专门为其制作的API Python 3.

如何在保持python 2.7.6(当前版本)完整的同时pip安装Python 3 ？
