python安装TensorFlow问题 解决Cannot uninstall 'wrapt'.It is a distutils installes project

pip install tensorflow时

1.遇到了
ERROR: Cannot uninstall ‘wrapt’. It is a distutils installed project and thus we cannot accurately determine which files belong to it which would lead to only a partial uninstall.

办法：输入 pip install -U --ignore-installed wrapt enum34 simplejson netaddr

2.遇到了
ERROR: tensorboard 1.14.0 has requirement setuptools>=41.0.0, but you’ll have setuptools 39.1.0 which is incompatible.

原因： setuptools 版本太低

办法：更新setuptools版本 输入 pip install --upgrade setuptools
