Tensorflow安装错误消息，“ SyntaxError”？

Question

I'd like to install tensorflow using pip in python 3.7 on windows 10 using the command-line as administrator.

First time installing tensorflow and I get error messages:

(SyntaxError: unexpected character after line continuation character) or (SyntaxError: invalid syntax).

I have tried the various ways shown below:

# OPENING PYTHON AS ADMINISTRATOR

Type "help", "copyright", "credits" or "license" for more information.

python -m pip install tensorflow works well on my windows7 system. I am currently using python3.6 64 bit version. Before you execute "python -m pip install tensorflow" from commandline, set the "PATH" in environment variable to 'python.exe'
