WSL Ubuntu Cargo Rust openssl 环境变量未设置

Question

我已经尝试安装和重新安装 pkg-config 和 libssl-dev。看起来好像在安装时未设置 openssl 环境变量。所有其他帖子都建议安装 pkg-config 和 libssl-dev 但这在这里不起作用。有什么建议么？

\n

我认为这与 WSL 有关，因为它在完整的 Ubuntu 安装上运行得很好。

正如评论所述，OpenSSL3.x可能不兼容，但您可以安装最新1.1.1版本：

# latest March 2023 release 

ENV OPENSSL_DIR="/opt/openssl"

curl "https://www.openssl.org/source/openssl-1.1.1t.tar.gz" \
  --output "/tmp/openssl.tar.gz"
mkdir --parent "/tmp/openssl"
tar \
  --extract \
  --file="/tmp/openssl.tar.gz" \
  --strip=1 \
  --directory="/tmp/openssl"
( \
  cd "${TMP}/openssl" \
  ./config \
    --prefix="/opt/openssl" \
    --openssldir="/opt/openssl" \
  make && make install \
)

笔记：

• 1.1.1 得到积极维护，截至 2023 年 3 月，报告的漏洞已减少
• 3.x版本最近存在漏洞

1.1.1因此，如果可以的话，现在坚持下去可能会更加谨慎。
