PyGithub authentication troubles

我正在使用带有来自 Github 的访问令牌的 PyGithub 我来到这里通过单击创建命令行工具。我的代码如下：

from github import Github

def readEnvironment():
'This function reads in the environment variables form a file if needed'
if os.path.isfile('.env') is True:
with open('.env', 'r') as file:
for line in file:
if line.startswith('#'):
continue
# Remove leading `export `
# then, split name / value pair
key, value = line.split('=', 1)
os.environ[key] = value

@click.group()
def cli():
pass

@click.command()
@click.option('--token', default=None, help='The Github access token', prompt=False)
def github(token):
if None == token and (None != os.environ['GITHUB_ACCESS_TOKEN'] or '' != os.environ['GITHUB_ACCESS_TOKEN']):
token = os.environ['GITHUB_ACCESS_TOKEN']
client = Github(token)
print(client)

# Then play with your Github objects:
for repo in client.get_user().get_repos():
print(repo.name)

cli.add_command(github)

if __name__ == '__main__':
readEnvironment()
cli()

但我收到以下错误

'

其中 omitted 是我从 Github 获得的访问令牌。正确的标记出现在错误中。这是 PyGithub 文档中给出的基本示例，所以我不确定我错过了什么。当我在 click 方法之外运行代码时，它工作正常。我正在使用 Python 3.7.2 和 PyGithub 1.45 并单击 7.0.

原来错误信息中的\
是关键。我在没有删除换行符的情况下读取环境变量。我将功能固定为

def readEnvironment():
'This function reads in the environment variables form a file if needed'
if os.path.isfile('.env') is True:
with open('.env', 'r') as file:
for line in file:
if line.startswith('#'):
continue
# Remove leading `export `
# then, split name / value pair
key, value = line.split('=', 1)
os.environ[key] = value[:-1]

然后一切正常。
