Ubuntu:pip不能使用python3.4

Question

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
Traceback (most recent call last):
File "/usr/local/bin/pip", line 9, in <module>
load_entry_point('pip==1.4.1', 'console_scripts', 'pip')()
File "/usr/local/lib/python3.4/dist-packages/setuptools-1.1.5-py3.4.egg /pkg_resources.py", line 357, in load_entry_point
def get_entry_info(dist, group, name):
File "/usr/local/lib/python3.4/dist-packages/setuptools-1.1.5-py3.4.egg/pkg_resources.py", line 2394, in load_entry_point
break
File "/usr/local/lib/python3.4/dist-packages/setuptools-1.1.5-py3.4.egg/pkg_resources.py", line 2108, in load
name = some.module:some.attr [extra1,extra2]
ImportError: No module named 'pip'

$ which pip
/usr/local/bin/pip

$ python2.7 -m pip //here can be just python, btw
Usage:   
/usr/bin/python2.7 -m pip <command> [options]
//and so on...

$ python3.4 -m pip
/usr/bin/python3.4: No module named pip

从home/user /.pip/pip.log:

Exception:
Traceback (most recent call last):
File "/usr/lib/python2.7/dist-packages/pip/basecommand.py", line 122, in main
status = self.run(options, args)
File "/usr/lib/python2.7/dist-packages/pip/commands/install.py", line 283, in run
requirement_set.install(install_options, global_options, root=options.root_path)
File "/usr/lib/python2.7/dist-packages/pip/req.py", line 1431, in install
requirement.uninstall(auto_confirm=True)
File "/usr/lib/python2.7/dist-packages/pip/req.py", line 598, in uninstall
paths_to_remove.remove(auto_confirm)
File "/usr/lib/python2.7/dist-packages/pip/req.py", line 1836, in remove
renames(path, new_path)
File "/usr/lib/python2.7/dist-packages/pip/util.py", line 295, in renames
shutil.move(old, new)
File "/usr/lib/python2.7/shutil.py", line 303, in move
os.unlink(src)
OSError: [Errno 13] Permission denied: '/usr/bin/pip'

没有/ usr/bin/pip btw.

我怎么能解决这个问题才能正常使用pip和python 3.4？我正在尝试使用pycharm,但它的包管理器也陷入了这个问题.

谢谢你的关注!

Answer 1

你为python 2安装了pip,但没有为python 3安装.

Ubuntu的分布python-pip,python3-pip,python-setuptools和python3-setuptools包,您可以安装(apt-get install如需要等).此后,请注意pip安装python 2,并pip3安装python 3(类似于python,和python3).

可以说Setuptools为包提供了python的"构建"过程,而Pip提供了它的"安装"过程.通常你想要两个礼物.

如果你想要最新的pip/setuptools,你总是可以从PyPA的bootstrap网站获得它:

$ curl https://bootstrap.pypa.io/get-pip.py | python3.4

之后,您可以为相应的python安装最新的setuptools,例如

$ python{2.7,3.4} -m pip install -U setuptools

如果您尝试为系统python安装这些,则可能需要root/sudo.

Answer 2

这适用于我的 Ubuntu 19.04：

sudo apt install python3-pip

然后pip3或python3 -m pip安装python包。

Answer 3

curl https://bootstrap.pypa.io/get-pip.py -o get-pip.py
sudo python3 get-pip.py

确认其安装：

pip3 --version    

要么

python3 -m pip --version

现在，使用以下命令安装所需的软件包（例如numpy）：

pip3 install numpy

要么

python3 -m pip install numpy
