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 github 问题中描述——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 目录中？

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

还有，

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

似乎我缺少各种依赖项——我将尝试重新安装

Answer 1

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

您将在那里拥有 Pip 或 easy_install（Python 安装工具的一部分），可用于安装 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：尝试此更正以轻松安装：

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。

另外，python3.5 -m ensurepip 命令缺少这个库：

sudo apt-get install libssl-dev

Answer 2

试试

sudo add-apt-repository ppa:deadsnakes/ppa

sudo apt update
sudo apt install python3.8 python3.8-dev python3.8-venv

sudo update-alternatives --install /usr/bin/python3 python3 /usr/bin/python3.8 2

python3 -V

Answer 3

所有不同的 Python 3.* 版本似乎都重复使用相同的 pip 位置，这使得调用特定 Python 版本变得困难。

但是，您可以通过将特定版本指定为模块来调用 pip。所以不要这样做：

pip3.5 install <blah>

在大多数发行版中不存在，请执行以下操作：

python3.5 -m pip install <blah>
