chroot中的Pip SSLError malloc失败

Question

我安装了一个基于debian（linaro）的rootfs.img.raw，它是基于稀疏映像（带有simg2img）创建的，并运行chroot：

$ sudo chroot /mnt/intrinsycimg qemu-aarch64-static /bin/bash

使用qemu模拟ARM64。

在python（3.7.3版）上使用pip（18.1版），我尝试使用它安装随机软件包，但出现以下错误：

我尝试根据此--trusted-host添加github issue answer标志，但发生了malloc失败：

我还尝试将/run，/dev，/sys和/proc（例如sudo mount --rbind /run/ /mnt/linaroimg/run/）挂载为this user suggested，但得到的结果相同。

我的openssl版本是OpenSSL 1.1.1d，但发现有关malloc failure for 1.1.1d的问题，因此，如果我运行相同的命令，则会出现相同的错误：

    self = _SSLContext.__new__(cls, protocol)
ssl.SSLError: [SSL] malloc failure (_ssl.c:2994)

我尝试手动编译OpenSSL_1_1_1g版本：

root@user:/home/linaro# openssl version
OpenSSL 1.1.1g  21 Apr 2020 (Library: OpenSSL 1.1.1d  10 Sep 2019)

但最终结果相同。我对Library: OpenSSL 1.1.1d表示怀疑，但是我git克隆了openssl存储库并签出了OpenSSL_1.1.1g标签。我也想避免自己编译openssl，因为我以后更喜欢通过apt更新它。

关于如何解决此问题的任何想法？

这里的问题是您使用的是旧版本的QEMU，它在linux用户模式支持中存在已知的错误（特别是多线程来宾程序存在问题）。尝试使用较新的版本（例如QEMU 5.0）应该会使错误消失。
