我正在尝试访问gmail api，因为我正在使用此rubygmail指南，但每次我尝试运行代码时，我都会遇到不同的错误，我正在使用此代码：
require 'google/apis/gmail_v1'
require 'googleauth'
require 'googleauth/stores/file_token_store'
require 'fileutils'
OOB_URI = 'urn:ietf:wg:oauth:2.0:oob'
APPLICATION_NAME = 'Gmail API Ruby Quickstart'
CLIENT_SECRETS_PATH = 'client_secret.json'
CREDENTIALS_PATH = File.join(Dir.home, '.credentials',
"gmail-ruby-quickstart.yaml")
SCOPE = Google::Apis::GmailV1::AUTH_GMAIL_READONLY
##
# Ensure valid credentials, either by restoring from the saved credentials
# files or intitiating an OAuth2 authorization. If authorization is required,
# the user's default browser will be launched to approve the request.
#
# @return [Google::Auth::UserRefreshCredentials] OAuth2 credentials
def authorize
FileUtils.mkdir_p(File.dirname(CREDENTIALS_PATH))
client_id = Google::Auth::ClientId.from_file(CLIENT_SECRETS_PATH)
token_store = Google::Auth::Stores::FileTokenStore.new(:file => 'gmail-ruby-quickstart.yaml')
authorizer = Google::Auth::UserAuthorizer.new(
client_id, SCOPE, token_store)
user_id = 'me'
credentials = authorizer.get_credentials(user_id)
if credentials.nil?
url = authorizer.get_authorization_url(
base_url: OOB_URI)
puts "Open the following URL in the browser and enter the " +
"resulting code after authorization"
puts url
code = gets
credentials = authorizer.get_and_store_credentials_from_code(
user_id: user_id, code: code, base_url: OOB_URI)
end
credentials
end
# Initialize the API
service = Google::Apis::GmailV1::GmailService.new
service.client_options.application_name = APPLICATION_NAME
service.authorization = authorize
# Show the user's labels
user_id = 'me'
result = service.list_user_labels(user_id)
puts "Labels:"
puts "No labels found" if result.labels.empty?
result.labels.each { |label| puts "- #{label.name}" }
当我运行ruby代码时，我收到此错误：
nilay@nilay:~/gmail$ ruby quickstart.rb
/home/nilay/.rbenv/versions/2.3.1/lib/ruby/2.3.0/pstore.rb:414:in `load_data': PStore file seems to be corrupted. (PStore::Error)

我该如何解决这个问题，请帮助我。
