我遇到同样的问题
ERROR: Could not install packages due to an EnvironmentError: [Errno 2] No such file or directory: '/root/anaconda3/lib/python3.6/site-packages/tornado-6.0.4.dist-info/metaDATA
然后我
cd /root/anaconda3/lib/python3.6/site-packages/tornado-6.0.4.dist-info/&& ls
DEscriptION.rst LICENSE.txt metadata.json
最后，我确实
cp metadata.json metaDATA解决了问题。也许这对您有帮助。
