[英]Install pip for python 3.5
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——出于此github 问题中描述的原因——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
我找不到升级到 pip3.5 的任何支持

正如@fwalsh 推荐的那样
kendall@kendall-Macmini:~/Downloads$ python3.5 get-pip.py
Traceback (most recent call last):
File "get-pip.py", line 19177, in <module>

似乎我缺少各种依赖项——我要尝试重新安装
检查:/usr/local/lib/python3.5/dist-packages
你要么有 Pip 要么有 easy_install(Pythons 安装工具的一部分),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
另一种选择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:尝试此更正以方便安装:
sudo apt-get install python3-setuptools
sudo python3.5 /usr/local/lib/python3.5/dist-packages/easy_install.py pip
我假设这是它安装到的目录。
此外,您缺少python3.5 -m ensurepip
命令的这个库:
sudo apt-get install libssl-dev
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
