在centos7上安装颤振:什么是centos7中的debian包lib32stdc++6？

Question

我正在安装一个centos7码头容器中的颤振。它在抱怨有些可执行的文件不能执行。有一个解决方案，但不是针对centos7的：

[!] Flutter (Channel @{u}, v0.0.0-unknown, on Linux, locale en_US)
    ✗ Downloaded executables cannot execute on host.
      See https://github.com/flutter/flutter/issues/6207 for more information
      On Debian/Ubuntu/Mint: sudo apt-get install lib32stdc++6
      On Fedora: dnf install libstdc++.i686
      On Arch: pacman -S lib32-libstdc++5

在https://pkgs.org上搜索lib32stdc++6、libstdc++.i686、lib32-libstdc++5并没有显示centos7的包。github的问题根本没有提到中心。

我需要在我的centos7码头容器中安装哪个centos7包才能顺利运行？

这个问题似乎与Flutter version Unknown有关

我已经安装了最新的git版本，正如所描述的here。不过，我还是会犯同样的错误。

Answer 1

最终修正的是，这句话隐藏在一个Github的问题中：

https://github.com/flutter/flutter/issues/6207#issuecomment-373100050

cd flutter/bin/cache/artifacts/engine
cp android-arm64-profile/linux-x64/gen_snapshot android-arm-profile/linux-x64/gen_snapshot
cp android-arm64-release/linux-x64/gen_snapshot android-arm-release/linux-x64/gen_snapshot

2018年10月更新:我们已经放弃了这个修复程序，因为这个应用程序是这样在设备上崩溃的。解决方案是在centos7上构建颤振应用程序。我们现在使用基于这个Dockerfile的Docker容器：

对于CentOS 7.x，请尝试安装libstdc++软件包。

包查询：yum search libstdc++

安装软件包：yum install libstdc++

libstdc++是CentOS 7.x标准发行版的一部分
