pip 使用代理方式
|
选择喜欢的代码风格
在使用
pip install 的时候经常卡顿甚至无法下载，可以通过 --proxy 走代理方式。
pip --proxy
pip 要通过代理服务器安装 Python 包，请执行以下操作：
Linuxsudo pip install --proxy http://<usr_name>:<password>@<proxyserver_name>:<port#> <pkg_name>Windows
pip install --proxy http://<usr_name>:<password>@<proxyserver_name>:<port#> <pkg_name>
例如我在下载 Python 的 EasyOCR 的包、Pytorch，可以类似这样：
pip3 install torch torchvision torchaudio --proxy http://127.0.0.1:1080 --index-url https://download.pytorch.org/whl/cu117
...
pip install --proxy http://127.0.0.1:1080 easyocr
...
