今天尝试使用时gsutil出现以下错误：
+ gsutil cp -nra public-read a gs://b
/usr/local/lib/python2.7/dist-packages/cryptography/__init__.py:39: CryptographyDeprecationWarning: Python 2 is no longer supported by the Python core team. Support for it is now deprecated in cryptography, and will be removed in a future release.

我正在使用 Python 2 ( export CLOUDSDK_GSUTIL_PYTHON=python2) 运行 gsutil，似乎该工具或操作系统在一夜之间安装了 bcrypt 3.2.0，不再支持 Python 2。
这会破坏 gsutil 工具。
答案1
修复方法是在运行该工具之前手动降级到 bcrypt 3.1.7：
sudo pip install --system bcrypt==3.1.7
