离子框架：创建项目时离子构建失败（v4.12.0）

Question

I have ionic installed in my system. When i run ionic run app tabs it installs all the npm packages but then the prompt falls to

Downloading binary from https://github.com/sass/node-sass/releases/download/v4.11.0/linux-x64-72_binding.node
Cannot download "https://github.com/sass/node-sass/releases/download/v4.11.0/linux-x64-72_binding.node":

HTTP error 404 Not Found

Then it fails with the prompt showing

gyp ERR! build error 
gyp ERR! stack Error: `make` failed with exit code: 2

I have already tried removing node_modules and reinstall the packages. I tried reinstalling ionic-cli as well. Which doesn't work.

I'm using node v12.0.0 npm v6.9.0 ionic v4.12.0

Answer 1

Indeed, the version https://github.com/sass/node-sass/releases/download/v4.11.0/linux-x64-72_binding.node is not available because you are using node v12 and try to get unsupported version of node-sass for node v12.

The solution is to downgrade your node version to v11 or upgrade your node-sass dependency to the latest.

If you (for visitors having the same issue w/ another library. Here, it is ionic ) are using node-sass as a vendor library, downgrade to node v11 and notify the library developer team to the need for an update.

另一种选择是将节点 11 添加到您的开发依赖项中：

npm i --save-dev node@11
