为google存储桶创建签名URL

Question

我正在尝试创建一个签名的URL，并将其运行到缺少的库pyopenssl问题中。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

我收到以下错误：

CommandException: signurl命令需要pyopenssl库(尝试pip安装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

我的问题是:出于某种原因(我认为) gsutil仍然指python2.5，这是MacOS附带的版本&没有安装pip。您知道如何使gsutil使用最新版本的python和后续库吗？

Answer 1

您可以运行gsutil -D version，并获得关于gsutil安装、用于运行它的Python、正在加载的配置文件等方面的有用调试信息。

如果您正在运行gsutil的gcloud安装，那么在您的输出中应该会看到如下所示的一行：

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环境变量正如这些文档中所提到的指定您首选的Python解释器的路径。

但是，如果您正在运行一个独立的安装gsutil (不是gcloud安装的一部分)，那么您应该确保通过命令/usr/bin/env python启动的PATH版本是正确的版本--这将是从PATH环境变量中指定的目录中发现的第一个Python二进制文件，因此您可能必须适当地编辑和export您的PATH。
