Question

刚刚向Eclipse添加了Mercurial插件（1.4.12.86）（Web Dev Version，Build id：20090920-1017），并在启动时遇到此错误：

Cannot run program "hg": CreateProcess error=2, The system cannot find the file specified

找到thread on the same problem，但不知道如何修复它。

以下是日志中的更多内容：

Answer 1

你在本地安装了mercurial吗？即。你能从命令行/ dos框运行hg吗？如果没有，你需要从那开始 - 从Mercurial网站获取它。

Answer 2

您可能在Windows上本地安装了mercurial，但是自安装以来还没有重新启动Windows。重新启动后，eclipse插件将能够找到mercurial安装。

Answer 3

实际上，并不完全。 Eclipse Mercurial插件要求您安装hg命令行实用程序，它们是python程序。这意味着你必须安装python（最低2.6）。这意味着Eclipse将执行Python脚本时遇到问题，直到您执行Eclipse理解的程序（如DOS批处理脚本）执行hg python脚本。

然后，毕竟，也许你最终能够检查出来的东西（复制，克隆他们在Mercurial世界中称之为的东西）。

如何正确设置Eclipse的Mercurial插件？
