That's actually an issue with Bcrypt itself.
Bcrypt depends on node-gyp for native code which installs using prebuilt binaries. If it doesn't find a pre-built binary for the version you are using (like it doesn't have one for your versions [email protected] and [email protected]) then it tries to build it from the source. This requires you to have Python 2, a C++ compiler, and a make system installed. And it isn't finding it on your system so it is failing.
You can either install those and have your computer build the binary you need or you can do a workaround like I did.
Remove bcrypt and bcrypt-promise, and install bcrypt-nodejs. Then replace the requires for bcrypt with require('bcrypt-nodejs').
I couldn't get bcrypt-nodejs-as-promised to replace bcrypt-promise so I had to write my own function for the hash promise in user.model.js:
async function bcryptHash(bPass, bSalt) { return await new Promise((resolve, reject) => { bcrypt.hash(bPass, bSalt, null, function (err, hash) { if (err) reject(err) resolve(hash) }); }) }
And then in the call to the bcrypt_p.hash I just replace it with my own function :
[err, hash] = await to(bcryptHash(user.password, salt));
This got it running for me without installing the Python 2, a C++ compiler, and a make system.
如果bcrypt报错，大部分原因是因为bcrypt的版本与node版本出现了不兼容导致的。解决这个问题比较简单。首先删掉node_modules和package-lock.json。然后到npm网站查询bcrypt与node对照表。node版本在10,11版本，bcrypt使用>=3;node版本在12，bcrypt使用>= 3.0.6；因为我的node版本是14.18，所以我直接把bcrypt版本改成了5.0.1，然后npm install，成功安装，没报错。
