esm.sh在Deno deploy下报错

问答
#1

Deno deploy环境下esm.sh会默认把导入的包target设置为deno导致报错"TypeError: Can not modify env vars during execution."
原因可能是默认设置了Process.env.NODE_ENV为production

哪个包？有没有可以复现的 repo？

#4

最近更新 esm.sh 把 process 的 polyfill 切换到了 deno.land/std/node/process.ts，我修复一下

#5

添加了一个issue：https://github.com/esm-dev/esm.sh/issues/261 ，晚点我更新一下

@so1ve 谢谢反馈，建议遇到问题可以尝试在github上提交issues，这样维护者也能及时收到邮件，也方便问题追踪。

哈哈哈哈好的，主要是不太确定这个是否是一个BUG :joy:

#8

如果添加?target=es2021就可以解决了

#9

在 v65 里修复这个问题了

#10 
import AV from "https://esm.sh/leancloud-storage@4.12.0?target=deno&pin=v65";
import * as leanAdapters from "https://esm.sh/@leancloud/platform-adapters-node@1.5.2?target=deno&pin=v65";
AV.setAdapters(leanAdapters);

报错

Found 3 errors.

target设置为es2021依然没有这个问题:nauseated_face:会不会是命名冲突

可以试试升级到 Deno 1.18.2，加上 --unstable 参数，process deno ployfill 用了一下不太稳定的api
