最小示例:
pip install tensorflow==2.9.1 non-existing==1.2.3
Defaulting to user installation because normal site-packages is not writeable
Looking in indexes: https://pypi.org/simple, https://pypi.ngc.nvidia.com
Collecting tensorflow==2.9.1
Downloading tensorflow-2.9.1-cp310-cp310-manylinux_2_17_x86_64.manylinux2014_x86_64.whl (511.7 MB)

ERROR: Could not find a version that satisfies the requirement non-existing==1.2.3 (from versions: none)
ERROR: No matching distribution found for non-existing==1.2.3
所以pip首先下载(相当大的)TensorFlow，但then告诉我non-existing不存在.
有没有办法让它更早失败，例如，打印错误并退出before下载？
