安装pip出错，installed,plese add pip to your path

安装时出现： ----------- install QuantDigger -------------- ----------- install pip -------------- pip no install ============ downloading pip-6.0.8.tar.gz from:https://pypi.python.org/packages/source/p/pip/pip-6.0.8.tar.gz ============ extracting pip-6.0.8.tar.gz ============ installing pip ============ installed,plese add pip to your path

我尝试过python2.7.13和3.6版本，尝试手动安装pip6.0.8版本，也尝试过用anaconda2、3，同样会出现这样的提示。
