使用 npm 安装 bcrypt 时出错

我无法在我的机器上使用 npm安装 bcrypt，因为我遇到了以下错误。我一直在解决这个问题，但运气不佳。您能推荐一些诊断或修复问题的步骤吗? 这样我就可以成功地运行 npm install bcrypt了？

The easy solution is just switch from the "bcrypt" npm module to bycryptjs or bcrypt-nodejs. It's the exact same API, but pure JS so no native add-ons to deal with.

npm install --save bcryptjs && npm uninstall --save bcrypt

Then change your require calls to "bcryptjs", but all your code otherwise can be unchanged.

Long term, I suspect at the moment bcrypt may not be ready for node v0.12.0 yet, but if not it will eventually be updated and ready.

On Mac OS, after a Xcode update, running sudo gcc and accepting Xcode's new license solved the problem!

Had the same problem. Updating npm and try again (npm install -g npm usually). It fix the issue for me.

For windows install the following module:

npm install -g node-gyp
npm install --g --production windows-build-tools

Then try to install:

npm install bcrypt
小开

On this command:

npm install --g --production windows-build-tools

You may have to run this in Powershell as administrator on your Windows machine.

You do that by right-clicking on Powershell and select "Run As Administrator"

I just ran the following then tried the install and it worked:

npm install node-pre-gyp -g

I was facing the same issue on the server side( aws ubuntu 16.04).

I tried deleting node_module/bcrypt by sudo rm -rf node_module/bcrypt multiple times and reinstalled it again and again by various ways but still facing the same issue.

I checked node version with nvm and it was also showing stable (v10.11.0).

Finally, I tried. 

sudo npm cache clean -f
sudo npm install -g n
sudo n stable

and it worked for me.

If you are on windows run powershell as administrator and use these commands.

npm install --g --production windows-build-tools

and then install bcrypt using

npm install --save bcrypt
小开

I was also having the same problem. The following commands helped me.

npm rebuild

then 

npm install bcrypt
小开

Reason for Error : Node maybe can’t able to find the Python path on your system

Solution

step: 1 Rum command prompt as administrator step 2 Install the package 

  npm install --global --production windows-build-tools

It may take some while, keep patient

step 3 Now install 

npm install node-gyp

Last step Now you are ready to Go

npm install bcrypt
小开

if any of the above fails to work, do:

npm install node-gyp

Afterwards visit the official python download site Official Python download link

Install the latest version of python, make sure to check add python to path add python to path

After installation, do:

npm --save install bcrypt

I managed to solve this by running the command: sudo apt-get install -y build-essential python and then yarn add bcrypt.

You can find the instructions here:

I installed bcrypt-nodejs though it's already deprecated, and then removed it and installed bcrypt again. Like this, I Installed bcrypt successfully and it worked fine.

yarn add bcrypt-nodejs
yarn remove bcrypt-nodejs
yarn add bcrypt
小开

The accepted solution works, but bcryptjs is slower than python and C++ version.

If you still want bcrypt instead of bcryptjs, working solutions are the commands below, but they can also have their own problems.

✔️ npm install -g node-gyp
❌ npm install --g --production windows-build-tools

In Windows, the second command will try to install Visual Studio along with python and hence the problem arises because the Visual Studio installation takes a lot of time. Also it also hinders the installation of python. If you forget to run those commands as Administrator, then they will get installed at C:\Users\User.windows-build-tools which will still not work because node will search for python in C:\ or C:\Program Files. Hence these commands in some cases may increase your complications.

So the best idea for you is to ✔️install python manually for All Users. It is not necessary to add python to the environment path.

Then run:

✔️ npm install -g node-gyp

Now you are ready to install bcrypt:

npm install bcrypt

Upgrade to bcrypt@5.0.0

npm i bcrypt@5.0.0

I am not getting errors on this newer version of bcrypt, older version gave different types of errors ranging from not able to install bcrypt to typescript type errors

小开

Running

sudo apt install build-essential

installs all the tools you need to install bcrypt on Linux. Then you can run

npm install
小开

I had node version 12.18.3 and fixed the same by running npm i bcrypt@3.0.6

小开

This happened to me as I was installing a package from github that had an older version of bcrypt as a dependency. I just uninstalled the old bcrypt version and installed the newest version:

    npm uninstall bcrypt
npm install bcrypt

Then, voila. It worked.
