npm 恢复默认镜像以解决 RequestError: Hostname/IP does not match certificate's altnames 的错误

今天在初始化一个项目的时候执行 npm install 遇到报错：

npm ERR! RequestError: Hostname/IP does not match certificate's altnames: Host: npm.taobao.org. is not in the cert's altnames: DNS:*.tbcdn.cn, DNS:*.taobao.com, DNS:*.alicdn.com, DNS:*.cmos.greencompute.org, DNS:cmos.greencompute.org, DNS:m.intl.taobao.com...

后面太长就省略了。

看起来是之前 taobao 镜像迁移，证书过期引起的问题。

用 npm config list 看了一下配置，发现了很多 npm.taobao.org 域名。看来要彻底清除一下了。

1. 用 npm config ls | grep taobao 命令找出这些无效的 url:

chromedriver-cdnurl = "https://npm.taobao.org/mirrors/chromedriver" 
couchbase-binary-host-mirror = "https://npm.taobao.org/mirrors/couchbase/v{version}" 
debug-binary-host-mirror = "https://npm.taobao.org/mirrors/node-inspector" 
disturl = "https://npm.taobao.org/dist"

fuse-bindings-binary-host-mirror = "https://npm.taobao.org/mirrors/fuse-bindings/v{version}" 
git4win-mirror = "https://npm.taobao.org/mirrors/git-for-windows" 
gl-binary-host-mirror = "https://npm.taobao.org/mirrors/gl/v{version}" 
grpc-node-binary-host-mirror = "https://npm.taobao.org/mirrors" 
hackrf-binary-host-mirror = "https://npm.taobao.org/mirrors/hackrf/v{version}" 
leveldown-binary-host-mirror = "https://npm.taobao.org/mirrors/leveldown/v{version}" 
leveldown-hyper-binary-host-mirror = "https://npm.taobao.org/mirrors/leveldown-hyper/v{version}" 
mknod-binary-host-mirror = "https://npm.taobao.org/mirrors/mknod/v{version}" 
node-sqlite3-binary-host-mirror = "https://npm.taobao.org/mirrors" 
node-tk5-binary-host-mirror = "https://npm.taobao.org/mirrors/node-tk5/v{version}" 
nodegit-binary-host-mirror = "https://npm.taobao.org/mirrors/nodegit/v{version}/" 
operadriver-cdnurl = "https://npm.taobao.org/mirrors/operadriver" 
phantomjs-cdnurl = "https://npm.taobao.org/mirrors/phantomjs" 
profiler-binary-host-mirror = "https://npm.taobao.org/mirrors/node-inspector/" 
puppeteer-download-host = "https://npm.taobao.org/mirrors" 
python-mirror = "https://npm.taobao.org/mirrors/python" 
rabin-binary-host-mirror = "https://npm.taobao.org/mirrors/rabin/v{version}"

utp-native-binary-host-mirror = "https://npm.taobao.org/mirrors/utp-native/v{version}" 
zmq-prebuilt-binary-host-mirror = "https://npm.taobao.org/mirrors/zmq-prebuilt/v{version}" 

共计 30 个。

重置的办法就是删除掉。

可以用 npm config delete <config_name> 的方法删除，不过前提是用 awk 命令提取一下参数，免得一条条复制。

2. 使用 npm config ls | grep taobao | awk -F ' *= *' '{print $1}' 命令将配置名称全部提取出来

$ npm config ls | grep taobao | awk -F ' *= *' '{print $1}'

3. 复制到 sublime 或 vscode 中使用行编辑添加上前缀 npm config delete ，再执行。

4. 重新执行 npm install，顺利安装，问题解决。
