在安装Tensorflow时，如何修复"pip配置了需要TLS/SSL的位置，但是Python中的ssl模块不可用“？

Question

我试图用Anaconda3.9.9安装TensorFlow。

我执行了命令

pip install tensorflow

有个错误说：

WARNING: pip is configured with locations that require TLS/SSL, however the ssl module in Python is not available.
WARNING: Retrying (Retry(total=0, connect=None, read=None, redirect=None, status=None)) after connection broken by 'SSLError("Can't connect to HTTPS URL because the SSL module is not available.")': /simple/tensorflow/
Could not fetch URL https://pypi.org/simple/tensorflow/: There was a problem confirming the ssl certificate:  HTTPSConnectionPool(host='pypi.org', port=443): Max retries exceeded with url: /simple/tensorflow/ (Caused by SSLError("Can't connect to HTTPS URL because the SSL module is not available.")) - skipping
ERROR: Could not find a version that satisfies the requirement tensorflow (from versions: none)
ERROR: No matching distribution found for tensorflow

我尝试将/anaconda3、/anaconda3/Scripts和/anaconda3/library/bin添加到Path变量中。我还尝试运行以下命令：

pip install --trusted-host pypi.org --trusted-host pypi.python.org --trusted-host files.pythonhosted.org tensorflow

但似乎什么都没起作用。

我错过了什么吗?还有别的解决办法吗？

尝试在命令下面运行以修复此问题：

pip install --upgrade
pip install ssl

请创建一个virtual_environment以在Anaconda中安装TensorFlow。

按照下面的代码在virtual_environment中安装virtual_environment：

conda create -n tf tensorflow  #Create a Virtual environment(tf).
conda activate tf              #Activate the Virtual environment
pip install tensorflow         #install TensorFlow in it.

注意：每次使用TensorFlow时都需要激活virtual_environment。
