安装 frappe 时出错：权限被拒绝：CentOS 7 上的“纱线”

Question

我正在尝试在预装了 CentOS 7 和 Plesk 的 VPS 上安装 ERPNext。

在我需要使用此命令的步骤：

 bench init --frappe-branch version-12 frappe-bench

我收到此错误：

[frappe@musing-carver npm]$  bench init --frappe-branch version-12 frappe-bench
$ /usr/local/bin/virtualenv --quiet env -p python3
$ /usr/lib/node_modules/npm/frappe-bench/env/bin/python -m pip install --quiet --upgrade pip

我正在一步一步地学习这个教程：How To Install ERPNext in CentOS / RHEL || Erpnext || TechHack Tamil

我有 nodejs v10 而不是 v14 或 v16，¿这是个问题吗？

提前谢谢你

Answer 1

在执行命令前尝试使用 sudo

sudo  bench init --frappe-branch version-12 frappe-bench

告诉我结果

Answer 2

我已经解决了这个问题。

我只是重新安装了 yarn，现在它可以工作了。

sudo yum install yarn

我不知道它之前失败的确切原因......欢迎任何澄清。
