python安裝web.py遇到的問題python setup.py egg_info及解決方法

操作系統:window10

python版本:3.65

1.嘗試安裝，報錯

pip install web.py

ModuleNotFoundError: No module named 'utils'

Command "python setup.py egg_info" failed with error code 1 in C:\Users\Administrator\AppData\Local\Temp\pip-install-j9kbgtqp\web.py\

*提示缺少模塊utils

pip install utils

安裝之後，再次運行

pip install web.py

ModuleNotFoundError: No module named 'db'

Command "python setup.py egg_info" failed with error code 1 in C:\Users\Administrator\AppData\Local\Temp\pip-install-rjqj7n2r\web.py\

*提示缺少模塊db

pip install db

安裝成功之後，提示下面的錯誤，困擾許久

SyntaxError: Missing parentheses in call to 'print'. Did you mean print("var", var)?

Command "python setup.py egg_info" failed with error code 1 in C:\Users\Administrator\AppData\Local\Temp\pip-install-0zd81wui\web.py\

2.無意中發現web.py的官網中

web.py 0.39 is the latest released version of web.py. You can install it by running:

pip install web.py

The above version only supports Python 2. If you looking for Python 3 support, try the experimental version.

pip install web.py==0.40-dev1

意思是如果想要用python3，嘗試安裝下面這行版本爲0.40的。問題解決。可成功安裝

3.需要注意的是，安裝0.40版本web.py，不需要utils及db模塊的前置安裝。
