Errors when installing on Windows 10

I get this after run npm install -g backslide

npm ERR! hummus@1.0.82 install: `node-pre-gyp install --fallback-to-build`
npm ERR! Exit status 1
npm ERR!
npm ERR! Failed at the hummus@1.0.82 install script 'node-pre-gyp install --fallback-to-build'.
npm ERR! Make sure you have the latest version of node.js and npm installed.
npm ERR! If you do, this is most likely a problem with the hummus package,
npm ERR! not with npm itself.
npm ERR! Tell the author that this fails on your system:
npm ERR!     node-pre-gyp install --fallback-to-build

and the root cause

gyp ERR! stack Error: Can't find Python executable "C:\Users\zhang\Anaconda3\python.EXE", you can set the PYTHON env variable.
gyp ERR! stack     at Object.failNoPython (C:\Users\zhang\AppData\Roaming\npm\node_modules\backslide\node_modules\node-gyp\lib\configure.js:483:19)

But I do have C:\Users\zhang\Anaconda3\python.exe and have my env variables set correctly (because I can enter the Python REPL by typing python in the CMD).

Could you please help me have a look?

Tried without proxy but it seems not to be the cause.

Then I searched “hummus node-pre-gyp install --fallback-to-build” on Google and found a solution

npm install -g node-gyp npm install --global --production windows-build-tools (for Windows users)

And then run npm install -g backslide. The error is still there (it is expected on Windows) but the installation will continue.

But the new problem is ERROR: Failed to download Chromium r499413 when installing package puppeteer 😵

After reinstallation it works. The second problem is just caused by the network.
