为什么运行gclient会产生更新错误？

Question

我根据http://commondatastorage.googleapis.com/chrome-infra-docs/flat/depot_tools/docs/html/depot_tools_tutorial.html#_setting_up克隆了depot_tools。

然后，当我运行"gclient“时，我得到了这个错误：

depot_tools update failed. Conflict in /usr/v8-7.7/depot_tools
fatal: Unable to create '/usr/v8-7.7/depot_tools/.git/index.lock': Permission denied

我在一台安装了RHEL8的ppc64le linux机器上运行，我的目标是尝试在这台机器上安装v8，但首先gclient需要工作。

我确实在机器上安装了python 2.7.15。

Answer 1

这是一个权限问题。我只需要调整我所在文件夹的权限。

Answer 2

当python3是我的默认python时，我也遇到了同样的错误。gclient很可能在python3下运行，而不是在python2下运行，这会导致这些错误您可以使用pyenv来管理python的多个并行安装。
