樹莓派 4、Python 2.7

Question

我將最新的操作系統安裝到我的新樹莓派 4。我在 python 2.7 中的舊 rpi3 上有很多代碼，但在 python 3.9 上沒有一個代碼。 我設法在新的 RPI4 上安裝了 python 2.7，但是 PIP 遇到了很大的問題。 Python 2.7 沒有模塊。 現在是 PIP 和 PIP3 全部用於 python 3.如何將 pip 路由到 python2.7 和 pip3 到 python3.9？ 我試試

sudo apt-get  install pip

Note, selecting 'python3-pip' instead of 'pip'
python3-pip is already the newest version (20.3.4-4+rpt1+deb11u1).
The following packages were automatically installed and are no longer required:
  docutils-common libfuse2 mypy pylint python3-astroid python3-asttokens
  python3-docutils python3-isort python3-jedi python3-lazy-object-proxy
  python3-logilab-common python3-mccabe python3-mypy python3-mypy-extensions
  python3-parso python3-pygments python3-roman python3-send2trash python3-toml
  python3-typed-ast python3-typing-extensions python3-wrapt sgml-base xml-core
  xsel
Use 'sudo apt autoremove' to remove them.

我想將請求安裝到 python 2.7

pip install requests
Defaulting to user installation because normal site-packages is not writeable
Looking in indexes: https://pypi.org/simple, https://www.piwheels.org/simple
Requirement already satisfied: requests in /usr/lib/python3/dist-packages (2.25.1)

Python 2.7 中仍然缺少模塊

謝謝

嘗試<python2.7 binary path> -m pip install requests 。 例如，在我的機器上它會是python2.7 -m pip install requests在你的可能只是python -m pip install requests
