代理环境下yarn install安装optipng-bin失败求助

问题描述

本地构建环境已部署squid-deb-proxy代理，执行以下命令构建依赖：

yarn install --https-proxy=http://192.168.100.40:8000 --proxy=http://192.168.100.40:8000 --verbose

同时已在~/.npmrc中配置代理：

proxy=http://192.168.100.40:8000
https-proxy=http://192.168.100.40:8000
https_proxy=http://192.168.100.40:8000

构建时其他包均能正常通过代理下载，但optipng-bin编译失败，错误日志如下：

需要强制optipng-bin使用代理完成构建。

解决方法

配置系统级环境变量
optipng-bin的构建脚本可能优先读取系统环境变量，在执行yarn install前设置代理：

export HTTP_PROXY=http://192.168.100.40:8000
export HTTPS_PROXY=http://192.168.100.40:8000
export NO_PROXY=localhost,127.0.0.1
yarn install --verbose

Windows环境替换为：

set HTTP_PROXY=http://192.168.100.40:8000
set HTTPS_PROXY=http://192.168.100.40:8000
yarn install --verbose

为optipng-bin单独配置代理
通过npm配置命令为该包单独设置代理参数，确保其构建脚本能读取到：

npm config set optipng-bin:proxy http://192.168.100.40:8000
npm config set optipng-bin:https-proxy http://192.168.100.40:8000
yarn install --verbose

临时修改构建脚本
若上述方法无效，可手动修改node_modules/optipng-bin/lib/install.js（安装失败后该文件已生成），在使用got发起请求的代码段中添加代理配置：
```
// 在got请求的options中添加proxy字段
const response = await got(url, {
  proxy: 'http://192.168.100.40:8000',
  // 保留原有其他配置
});
```
修改后重新执行yarn install --verbose。
切换代理镜像源
若代理仍无法生效，可将npm/yarn registry切换到国内镜像，直接获取预编译包：
```
yarn config set registry https://registry.npmmirror.com
yarn install --verbose
```
