code-coverage - Chromium Coverage 脚本 - 生成 HTML 时出错

问题描述

我在这里参考说明：https ://chromium.googlesource.com/chromium/src/+/refs/heads/main/docs/testing/code_coverage.md#coverage-dashboard

$ gn gen out/coverage \
    --args="use_clang_coverage=true is_component_build=false
    dcheck_always_on=true is_debug=false"
$ python tools/code_coverage/coverage.py \
    crypto_unittests url_unittests \
    -b out/coverage -o out/report \
    -c 'out/coverage/crypto_unittests' \
    -c 'out/coverage/url_unittests --gtest_filter=URLParser.PathURL' \
    -f url/ -f crypto/

运行第一条指令工作正常。运行第二个会导致以下错误跟踪：

使用 gn gen out/Default 编译 Chromium 可以正常工作。有什么建议么？系统：Ubuntu 20.04

最好的祝愿
