Python 3.9.5蟒蛇3 2021.11 Windows 10

每当我尝试安装spacy（pip install spacy）时，我都会得到一个：

WARNING: Retrying (Retry(total=4, connect=None, read=None, redirect=None, status=None)) after connection broken by 'ConnectTimeoutError(<pip._vendor.urllib3.connection.HTTPSConnection object at 0x00000175C6A0DA30>, 'Connection to pypi.org timed out. (connect timeout=15)')': /simple/spacy/

ERROR: Could not find a version that satisfies the requirement spacy (from versions: none)

我也尝试过（pip安装-U-spacy）

另一种方法是：

pip install -U pip setuptools wheel
pip install -U spacy
python -m spacy download en_core_web_sm

也失败了。

请帮帮我。

确保已使用以下配置代理：

export http_proxy=http://{username}:{password}@{server_address}:{port}

或者

export http_proxy=http://{server_address}:{port}

或直接使用pip：

pip install spacy --proxy=http://{the-proxy-adress-with-port-and-auth}
