Question

我对cPanel的经验很少，但是需要在cpanel上安装Laravel应用程序。我真的在努力解决这个问题。

这是我正在采取的步骤：

Git检出存储库
设置.env
composer安装
撰写者更新
chmod -R 775存储和chmod 775引导程序/缓存
npm install -g npm凉亭纱
纱线安装
下装
npm run dev
php artisan migration：fresh --seed

（所有步骤的原因是因为我正在设置自己购买的主题，该主题在cPanel之外的所有地方都适用。）

我遇到的问题是当我尝试安装npm时。

运行npm install时出现以下错误：

> pngquant-bin@3.1.1 postinstall /public_html/src/node_modules/pngquant-bin
> node lib/install.js

  ⚠ The `/public_html/src/node_modules/pngquant-bin/vendor/pngquant` binary doesn't seem to work correctly
  ⚠ pngquant pre-build test failed
  ℹ compiling from source
  ✖ Error: pngquant failed to build, make sure that libpng-dev is installed

    at maybeClose (internal/child_process.js:970:16)
    at Process.ChildProcess._handle.onexit (internal/child_process.js:259:5)

我尝试了各种资源：

https://github.com/imagemin/pngquant-bin/issues/78

https://github.com/papandreou/node-pngquant/issues/14

我可以告诉您已安装pngquant（直接从git和npm中尝试安装）仍然是相同的错误。

libpng-dev已安装（我认为）：

identify -list format | grep PNG

  JNG* PNG       rw-   JPEG Network Graphics
  MNG* PNG       rw+   Multiple-image Network Graphics (libpng 1.2.46,1.2.49)
  PNG* PNG       rw-   Portable Network Graphics (libpng 1.2.46,1.2.49)
       See http://www.libpng.org/ for details about the PNG format.
PNG24* PNG       rw-   opaque 24-bit RGB (zlib 1.2.3)
PNG32* PNG       rw-   opaque or transparent 32-bit RGBA
 PNG8* PNG       rw-   8-bit indexed with optional binary transparency

我已经尝试过了：

npm install imagemin-pngquant@5.0.1 --save
npm install pngquant-bin@3.1.1

仍然出现相同的错误

[~/public_html/src]# npm install pngquant-bin@3.1.1 --save

> pngquant-bin@3.1.1 postinstall /public_html/src/node_modules/pngquant-bin
> node lib/install.js

我还尝试将其添加到package.json

"resolutions": {
    "image-webpack-loader/imagemin-pngquant": "5.0.1"
  }

我的节点和npm版本是：

node -v v10.15.3

npm -v 6.9.0

最后，这是我的bin文件夹的样子：

[~/bin]# ls
./   bower@  node_modules/  npm-cli.js@  pngquant@  yarn.lock
../  node*   npm@           npx@         yarn@      yarnpkg@

对我来说，似乎pngquant已正确安装，但由于某种原因找不到libpng-dev？有什么想法吗？救命？！请帮忙。

首先请确保您确实拥有libpng-dev而不仅仅是libpng

dpkg -l libpng-dev

如果未返回任何东西，则说明您没有安装它，因此您还需要Essentials软件包，因此请确保您还拥有该软件包：

sudo apt install build-essential libpng-dev

完成此操作后，您很可能需要删除node_modules文件夹

rm -rf node_modules

然后再次运行npm install。
