為 python 3.5 安裝 pip

Question

解決方案我的用戶沒有 pip 目錄的權限，我使用sudo -H標志重新安裝了 Python 3.5

我正在嘗試使用 pip3 為 python 3.5 安裝 Tensorflow——出於此github 問題中描述的原因——但是當我使用sudo pip3 install *.whl安裝時，它會安裝到 python 3.4。

如何重定向pip3以安裝到我的 python 3.5 目錄中？

我在 Ubuntu 14.04 上運行

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

看起來我什至沒有為python 3.5安裝pip。 我該怎么做？

我試過了

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

還有，

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

我找不到升級到 pip3.5 的任何支持

正如@fwalsh 推薦的那樣

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

    import pip

似乎我缺少各種依賴項——我要嘗試重新安裝

Answer 1

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

你要么有 Pip 要么有 easy_install（Pythons 安裝工具的一部分），它可以用來安裝 Pip：

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

或者你可以試試：

python3.5 -m ensurepip

另一種選擇是嘗試從存儲庫安裝，包名稱取決於您的發行版：

sudo apt-get install python3-pip pip3

編輯：嘗試此更正以方便安裝：

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

我假設這是它安裝到的目錄。

此外，您缺少python3.5 -m ensurepip命令的這個庫：

sudo apt-get install libssl-dev

試試

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
