在 Node js (node-gyp) 中使用 npm install 安装 argon2 时出错

Question

我尝试使用在节点js上安装argon 2 npm install argon2 --save。我认为 python （不知道为什么）或 node-gyp 有问题。

PS C:\angular\backend> npm install argon2 --save

> argon2@0.21.0 install C:\angular\backend\node_modules\argon2
> node-gyp rebuild

预计安装 argon2 以便稍后用于散列。

从你的 anaconda 路径看来你正在使用 Python 3。

gyp ERR! stack Error: Command failed: C:\Users\matan\Anaconda3\python.EXE -c import sys; print "%s.%s.%s" % sys.version_info[:3];
gyp ERR! stack   File "<string>", line 1
gyp ERR! stack     import sys; print "%s.%s.%s" % sys.version_info[:3];
gyp ERR! stack                                ^
gyp ERR! stack SyntaxError: invalid syntax

这可以解释打印语句中的语法错误，因为它不是打印函数。尝试安装 python2，或者如果您已经安装了它，请确保它位于 python3 之前的路径中。
