为google存储桶创建签名URL的问题

Question

我正在尝试创建一个签名URL &运行它到丢失库pyopenssl问题。我的命令如下:

gsutil signurl -d 10d -u /Users/dineshc/Development/my_key.json gs://console.cloud.google.com/storage/browser/my_data

我得到以下错误:

commanddexception: signurl命令需要pyopenssl库(尝试pip install pyopenssl或easy_install pyopenssl)

我的操作系统配置如下:

uname      :    Darwin
ProductName:    macOS
ProductVersion: 11.4
BuildVersion:   20F71

I have python3.7 installed & I created symbolic link: 
ln -s /usr/local/bin/python3.7 /usr/local/bin/python

我的问题:由于某种原因(我认为)gsutil仍然指的是python2.5，这是MacOS自带的版本&没有安装PIP。是否知道如何使gsutil使用最新版本的python &随后库吗?

Answer 1

您可以运行gsutil -D version并获得许多有用的调试信息，关于您的gsutil安装，用于运行它的Python版本，正在加载的配置文件等。

如果您正在运行gsutil的gcloud安装，您应该在输出中看到如下一行:

gsutil path: <path-to-google-cloud-sdk>/bin/gsutil

在这种情况下，您应该能够使用CLOUDSDK_GSUTIL_PYTHON环境变量指定您首选的Python解释器的路径，正如这些文档中提到的。

但是，如果您运行的是独立安装gsutil(不是gcloud安装的一部分)，您应该确保通过命令/usr/bin/env python启动的Python版本是正确的版本——这将是从您的PATH环境变量中指定的目录中可发现的第一个Python二进制文件，因此您可能必须适当地编辑和export您的PATH。
