npm安装错误pngquant-bin

Question

我安装npm和所有的工作直到这个错误，我试图找出是什么导致这个问题，但没有成功。安装之后，我尝试运行'npm‘，但也有错误。我想是因为npm安装的问题。我试图安装pngquant模块，但也没有成功。

如果你知道一个方法，或者你已经面临同样的问题，请帮助我。我看到了关于它的其他问题，但有任何答复。请。

pngquant@4.0.0后安装/var/www/html/futebit/node_modules/pngquant-bin节点lib/install.js

Answer 1

Pngquant需要vcruntime140.dll。从C++下载并安装Visual 2015 64位和32位Visual可再发行版

Answer 2

错误状态为make sure that libpng-dev is installed。这意味着你可能错过了那个包裹。

在Debian/Ubuntu上，您可以使用sudo apt install libpng-dev修复它。对我起作用了。

Answer 3

似乎您正在尝试使用预编译的二进制pngquant-bin，但是由于操作系统中使用的库不兼容，所以失败了，因此有两种使用它们的方法：

1. 安装系统范围内的pngquant包，将节点包分开
2. 如果您正在使用旧操作系统，请尝试升级库，然后再次安装节点包。
3. 如果您有最新的操作系统，尝试将节点包升级到最新版本。
