build - 设置 Chrome 时出错

Question

从源代码设置 Chromium 时出现以下错误。
当我运行 gn gen out/Default

 gn gen out/Default
ERROR at //build/config/linux/pkg_config.gni:103:17: Script returned non-zero exit code.
    pkgresult = exec_script(pkg_config_script, args, "value")
                ^----------
Current dir: /opt/apps/chromium/chromium_src/src/out/Default/

Returned 1.
stderr:

  ^---------------------------------------
See //crypto/BUILD.gn:221:25: which caused the file to be included.
    public_configs += [ "//third_party/nss:system_nss_no_ssl_config" ].

我不知道如何解决这个问题。
我关注了https://chromium.googlesource.com/chromium/src/+/master/docs/linux_build_instructions.md
还提到了这些

无法获得更多详细信息。
这些讨论引用了 PKG_CONFIG_LIBDIR，但不清楚在哪里设置或准确使用它。
关于我可能遗漏的任何输入？

安装这个包解决了同样的问题

sudo apt-get update && sudo apt-get install pkg-config
