python - 为 python 3.5 安装 pip

Question

解决方案 我的用户没有 pip 目录的权限，我使用 sudo -H 标志重新安装了 Python 3.5

我正在尝试使用 pip3 为 python 3.5 安装 Tensorflow——原因在 this 中描述。 github 问题——但是当我使用 sudo pip3 install *.whl 安装时，它会安装到 python 3.4。

如何重定向 pip3 以安装到我的 python 3.5 目录？

我在 Ubuntu 14.04 上运行

kendall@kendall-Macmini:~/Downloads$ python3.4 -m pip --version
pip 8.1.2 from /usr/local/lib/python3.4/dist-packages/pip-8.1.2-py3.4.egg (python 3.4)
kendall@kendall-Macmini:~/Downloads$ python3.5 -m pip --version
/usr/local/bin/python3.5: No module named pip

看起来我什至没有为 python 3.5 安装 pip。我该怎么做？

我试过了

kendall@kendall-Macmini:~/Downloads$ pip install -U pip
Requirement already up-to-date: pip in /usr/local/lib/python3.4/dist-packages/pip-8.1.2-py3.4.egg

此外，

kendall@kendall-Macmini:~/Downloads$ whereis pip
pip: /usr/bin/pip /usr/bin/X11/pip /usr/local/bin/pip3.4 /usr/local/bin/pip /usr/local/bin/pip2.7 /usr/share/man/man1/pip.1.gz

我找不到任何升级到 pip3.5 的支持

根据@fwalsh 的推荐

kendall@kendall-Macmini:~/Downloads$ python3.5 get-pip.py 
Traceback (most recent call last):

看来我缺少各种依赖项——我要尝试重新安装

Answer 1

检查:/usr/local/lib/python3.5/dist-packages

你要么在那里有 Pip，要么有 easy_install(Python 设置工具的一部分)，它可以用来安装 Pip:

sudo apt-get install python3-setuptools
sudo python3.5 easy_install.py pip

或者你可以试试:

python3.5 -m ensurepip

另一个选项是尝试从存储库安装，包名称取决于您的发行版:

sudo apt-get install python3-pip pip3

编辑:尝试此更正以便于安装:

sudo apt-get install python3-setuptools
sudo python3.5 /usr/local/lib/python3.5/dist-packages/easy_install.py pip

我假设这是它的安装目录。

此外，您还缺少用于 python3.5 -m ensurepip 命令的库:

sudo apt-get install libssl-dev
