google cloud sdk安装错误:unicodedecodeerror:'ascii'编解码器无法在位置197中解码字节0xe2:序号不在范围内(128)

我的计算机(Mac)上的Google Cloud SDK安装过程失败,并给出了以下堆栈跟踪。

Traceback (most recent call last):
  File "/Users/ttn/Desktop/google-cloud-sdk/bin/bootstrapping/install.py", line 218, in <module>
    main()

UnicodeDecodeError: 'ascii' codec can't decode byte 0xe2 in position 197: ordinal not in range(128)

以下是更多详细信息:

系统的默认python版本

python -V
Python 3.6.1 :: Anaconda custom (x86_64)

用于云SDK的python版本。

echo $CLOUDSDK_PYTHON
/usr/bin/python2.7

检查gCloud命令

gcloud
-bash: gcloud: command not found

注意:这个问题可能看起来是重复的,但我尝试了一些门户上可用的解决方案,但没有对我有用。
