PackageKit：*无法posix_spawn:错误2

Question

我有一个安装程序内置在“软件包”工具。在安装时，无法postix_spawn: error 2消息正在显示。

你能帮我解决这个问题吗？

Answer 1

errno=2是ENOENT on macOS。

这可能是由#引起的！指令，该指令启动postinstall脚本，指定目标系统上不存在的程序。您应该验证包中的postinstall脚本是否指定了系统上存在的解释器的完整路径。

Answer 2

也许，您的shell脚本可能有问题(很可能是关于“散列-砰”，即#！指令)。

尝试以下步骤：

1. 在源代码中找到所有的预安装和后安装安装程序脚本。
2. 对于每个预安装/postinstall脚本: a.将整个脚本内容复制到一个新文件(例如preinstall_ new /postinstall_new)，但#除外！指令。在preinstall_new/postinstall_new文件顶部键入正在使用的#!/bin/bash或其他解释器(不要复制、使用键盘编写)。c.使preinstall_new/postinstall_new文件成为可执行文件(chmod +x preinstall_new) d.用新创建的preinstall_new/postinstall_ newly文件(mv preinstall_new preinstall)替换原来的预安装/postinstall脚本
3. 触发生成并验证安装程序。

Answer 3

我也有同样的问题，或者我认为。不管怎样，我发现它是如何在网上冲浪的。我不收任何学分。我试着遵循用户"Kienz“在上面说的话：https://jira.atlassian.com/browse/SRCTREE-7836

如果要在这里删除ctrl +c ctrl +v

{更改后，"hg日志“工作。但是您不能拉/推，因为"mercurial_credential_manager.py“不适用于Python3。如何禁用"mercurial_credential_manager.py"？

在我等了20多下，按下源树>首选项> mercurial选项卡后，按钮"Reset to integrated“将错误日志更改为"Mercurial integrated 4.6.1”。

还有其他问题，我开始使用终端进行git操作，至少SourceTree会帮助您可视化。
