我由于丢失的节点canvas-prexuilt而无法安装WebPack。
我该怎么办？
通过Homebrew的安装似乎已经过时了，因为它试图安装canvas-prebuilt的1.6.11版本，该版本于2017年左右发布，不再可用。最接近它的版本是1.6.15。
我建议您按照官方文档中的安装说明，以每项项目为基础通过npm进行安装：
npm install --save-dev webpack
npm install --save-dev webpack-cli
# or for a one-liner just do npm i webpack webpack-cli
请注意，它是不建议在全球安装WebPack(npm i -g webpack(，但要为您的每个项目安装它，因此可以并行使用该工具的不同版本。这将使您的生活在将来使用WebPack与各个开发时间的项目一起更轻松。
