我正在尝试使用以下命令在我的 MacOS Ventura 上安装 Flask:
Pip3 install Flask
这给了我以下错误:
abdullah@MacBook-Pro ~ % pip3 install flask
error: externally-managed-environment
× This environment is externally managed
╰─> To install Python packages system-wide, try brew install
xyz, where xyz is the package you are trying to
install.
If you wish to install a Python library that isn't in Homebrew,
use a virtual environment:
python3 -m venv path/to/venv
source path/to/venv/bin/activate
python3 -m pip install xyz
If you wish to install a Python application that isn't in Homebrew,
it may be easiest to use 'pipx install xyz', which will manage a
virtual environment for you. You can install pipx with
brew install pipx
You may restore the old behavior of pip by passing
the '--break-system-packages' flag to pip, or by adding
'break-system-packages = true' to your pip.conf file. The latter
will permanently disable this error.
If you disable this error, we STRONGLY recommend that you additionally
pass the '--user' flag to pip, or set 'user = true' in your pip.conf
file. Failure to do this can result in a broken Homebrew installation.
Read more about this behavior here: <https://peps.python.org/pep-0668/>
note: If you believe this is a mistake, please contact your Python installation or OS distribution provider. You can override this, at the risk of breaking your Python installation or OS, by passing --break-system-packages.
hint: See PEP 668 for the detailed specification.
当我按照说明并尝试使用 Homebrew 命令安装它时:
brew install flask
它会产生以下错误:

To install flash, run:
brew install flash
Haroon@MacBook-Pro ~ % poetry install flask
Poetry could not find a pyproject.toml file in /Users/Haroon or its parents
这对我有用:
python3 -m venv 环境名称
源环境名称/bin/activate
pip3 安装 Flask
