Question

我正在安装npm，并且在此错误之前一切正常，我试图发现是什么导致了此问题，但没有成功。安装后，我尝试运行“ npm run dev”，但也出现错误。我猜是因为npm安装有问题。我试图安装pngquant-bin模块，但也没有成功。

如果您知道一种方法，或者已经遇到了相同的问题，请帮助我。我看到有关此问题的其他问题，但有任何答复。拜托。

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

Answer 1

Pngquant 需要 vcruntime140.dll。从 https://www.microsoft.com/en-in/download/details.aspx?id=48145

下载并安装适用于 Visual Studio 2015 的 64 位和 32 位 Visual C++ Redistributable

Answer 2

错误状态为make sure that libpng-dev is installed。这意味着您可能缺少该软件包。

在Debian / Ubuntu上，您可以使用sudo apt install libpng-dev进行修复。那对我有用。

Answer 3

您似乎正在尝试使用预编译的二进制 pngquant-bin ，但由于操作系统中使用的库不兼容而失败，因此有两种使用方式：

安装系统范围内的 pngquant 程序包，并将节点程序包分开
如果您使用的是旧操作系统，请尝试升级库，然后再次安装节点软件包
如果您具有最新的操作系统，请尝试将节点程序包也升级到最新版本。

npm install错误pngquant-bin
