当我试图连接到我朋友的服务器时,连接似乎是随机滞后的,有时是50‘s,40’s,60‘s,但有时是1,3或7秒

* Connected to ipaddress (ipaddress) port 80 (#0)

当我使用Nuxt3 + Vue阿波罗+ GraphQL,运行yarn build和node .output/server/index.mjs时,会得到以下错误:
Cannot find module '/mnt/d/projects/.output/server/node_modules/graphql/language/printer' imported from /mnt/d/projects/.output/server/chunks/app/server.mjs
Did you mean to import graphql/language/printer.js?
我有一个谷歌云服务帐户令牌,刚刚下载的。我想在Windows、Mac和Linux上激活它,作为CI管道的一部分。为此,我这样做: gcloud auth activate-service-account --key-file=./token.json 这在Linux和Mac上运行得很好。在Winddows上,我得到以下错误: ERROR: (gcloud.auth.activate-service-account) Could not read json file C:\Users\appveyor\token.json: No JSON object could be decoded 无论

所以我的Dockerfile是这样写的:
# set env vars for linux user
ENV LINUX_USER="kbuser"
...
... # other stuff
...
USER kbuser
但我想用

所以我只需要在文件中的一个地方写用户名。但这不管用。
我怎么才能避开这一切?
谢谢。

我的代码:

最近,我将我的Windows应用程序转换为Linux C++应用程序,并使用带有Debian的c++子系统交叉编译到Linux。但是,我通过使用json库得到了以下错误
no match for 'operator-' (operand types are '__gnu_cxx::__alloc_traits<std::allocator<double> >::value_type {aka double}' and 'nlohmann::basic_json<>::value_type {aka nlohmann::
