ssl - curl:(60)SSL证书问题:自签名证书

Question

我想在我的 Linux 计算机上安装 nvm。
(我的 Debian 版本是 10。)

我阅读了这份文件 https://github.com/nvm-sh/nvm#install--update-script
我输入了这个脚本。

curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.35.3/install.sh | bash

这就是结果。

 % Total    % Received % Xferd  Average Speed   Time    Time     Time  Current
                                 Dload  Upload   Total   Spent    Left  Speed
  0     0    0     0    0     0      0      0 --:--:-- --:--:-- --:--:--     0
curl: (60) SSL certificate problem: self signed certificate in certificate chain

curl failed to verify the legitimacy of the server and therefore could not
establish a secure connection to it. To learn more about this situation and
how to fix it, please visit the web page mentioned above.

我阅读了这份文件 https://curl.haxx.se/docs/sslcerts.html但我不明白该怎么做。于是上网一搜，发现需要代理配置。

export http_proxy="http://webfilter.**********.com:8000/"
export https_proxy="http://webfilter.**********.com:8000/"

我在终端中输入了这些命令并再次尝试了这个脚本。

curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.35.3/install.sh | bash

然后我得到相同的结果。

  % Total    % Received % Xferd  Average Speed   Time    Time     Time  Current
                                 Dload  Upload   Total   Spent    Left  Speed
  0     0    0     0    0     0      0      0 --:--:-- --:--:-- --:--:--     0

我该如何解决这个问题？

Answer 1

found that I need proxy configuration.

首先检查您在该调用之前是否确实需要任何代理。
For instance (没有导出代理):

curl -Is http://www.google.com | head -1 | grep 200; if [[ $? -eq 0 ]]; then; echo "Online"; else; echo "Offline"; fi

如果这有效，那么问题就不同了。
如果没有，请使用您的代理再试一次。
