颤振医生：为什么我会出现卷曲错误？

Question

我正确安装了flutter SDK，但是现在flutter doctor 不工作了。

$ set | grep SSL
SSL_CA_CERT_FILE=/Users/agoyal3/certs/ca.pem
SSL_CA_CERT_PATH=/Users/agoyal3/certs
SSL_CERT_FILE=/Users/agoyal3/certs/server-crt.pem
SSL_KEY_FILE=/Users/agoyal3/certs/server-key.pem

$ pwd
/Users/agoyal3/temp/flutter/bin

$ ./flutter doctor

curl: (60) SSL certificate problem: unable to get local issuer certificate
More details here: https://curl.haxx.se/docs/sslcerts.html

curl performs SSL certificate verification by default, using a "bundle"
 of Certificate Authority (CA) public keys (CA certs). If the default
 bundle file isn't adequate, you can specify an alternate file
 using the --cacert option.
If this HTTPS server uses a certificate signed by a CA represented in
 the bundle, the certificate verification probably failed due to a
 problem with the certificate (it might be expired, or the name might
 not match the domain name in the URL).
If you'd like to turn off curl's verification of the certificate, use
 the -k (or --insecure) option.

Answer 1

您的系统可能缺少有效的 SSL 证书。

尝试做：

1. 从here下载最新证书

2. 然后将此设置为 SSL_CA_CERT_PATH 并将文件设置为 SSL_CA_CERT_FILE

希望有帮助！
