Question

使用Webstorm和Node.js，我试图通过npm安装ursa模块。我需要这个模块，因为它是另一个模块的先决条件。

安装时，node-gyp rebuild上的安装失败。

控制台输出如下：

C:\Users\{Me}>npm install ursa --save
> ursa@0.9.4 install C:\Users\{Me}\node_modules\ursa
> node-gyp rebuild

C:\Users\Me\node_modules\ursa>if not defined npm_config_node_gyp 
(node "C:\Program Files\nodejs\node_modules\npm\bin\node-gyp-bin\\..
\..\node_modules\node-gyp\bin\node-gyp.js" rebuild )  else (node "" rebuild )

如果需要，我可以提供日志文件。

我用Google搜索并发现：

npm ERR！代码UNABLE_TO_GET_ISSUER_CERT_LOCALLY

此错误表示链中存在TLS证书    由未知的证书颁发机构（CA）签名。想必，    这是一个HTTPS代理使用的证书。    解决方案是配置cafile值：

$ npm config set cafile /path/to/your/file.pem

如果需要，可以使用以下命令从.crt生成.pem文件：

来源：https://github.com/npm/npm/wiki/Troubleshooting

$ openssl x509 -inform der -in /path/to/the.crt -out /path/to/the/file.pem

问题是，我如何知道安装失败的证书，以及如何生成.pem文件？我应该在哪里找到我的证书以及如何捆绑它们以获得一个.pem文件？（在Win 7上）

Answer 1

如果您是使用SSL检查交换SSL证书的公司防火墙，请向网络管理员询问证书文件。否则，您可以通过连接到交换证书的任何网站，使用Firefox或Chrome下载它。然后你可以使用NODE_EXTRA_CA_CERTS向Node.js提供证书文件，正如我在How to add custom certificate authority (CA) to nodejs中回答的那样。

npm错误UNABLE_TO_GET_ISSUER_CERT_LOCALLY，如何从一捆证书和该捆绑包中生成.pem文件？
