环境安装

Reids

安装

// 安装7.0.8 也可不指定版本 直接执行 sudo apt install redis-server
sudo apt install redis-server=5:7.0.8-4
// 检查安装的版本
redis-server --version
// 配置 apt 保持特定版本
// 安装后保持该特定版本而不自动升级，可以将该包保持在当前版本
sudo apt-mark hold redis-server

MariaDB

安装

// 安装 也可不指定版本 直接执行 sudo apt install mariadb-server
sudo apt install mariadb-server=1:10.11.2-1
// 在此安装过程中，系统将提示您设置 MySQL root 密码。如果未出现提示，则必须自行初始化MySQL服务器设置。您可以通过运行以下命令来执行此操作
// 请记住：只有在安装过程中未提示您输入密码时才运行它。
mysql_secure_installation
// 
sudo apt-get install mariadb-client-10.3

// 现在，编辑 MariaDB 配置文件。
vim /etc/mysql/my.cnf
// 并添加此配置
[mysqld]
character-set-client-handshake = FALSE
character-set-server = utf8mb4
collation-server = utf8mb4_unicode_ci

[mysql]
default-character-set = utf8mb4
// 现在，只需重新启动mysql服务，就可以开始了。
service mysql restart

// 查看版本
mysql --version
// 固定版本
sudo apt-mark hold mariadb-server

Node

tar -xvf node-v18.16.0-linux-x64.tar.gz
mv node-v18.16.0-linux-x64 /usr/local/nodejs

// 创建软连接
ln -s /usr/local/nodejs/bin/node /usr/local/bin/node
ln -s /usr/local/nodejs/bin/npm /usr/local/bin/npm

// 编辑环境变量
vim /etc/profile

export NODE_HOME=/usr/local/nodejs/
export PATH=$NODE_HOME/bin:$PATH
// 使环境变量生效
source /etc/profile

// 验证
node -v
npm -v

Yarn

npm install -g yarn@1.22.22

wkhtmltox

打开

https://wkhtmltopdf.org/downloads.html

下载

// 从 https://wkhtmltopdf.org/downloads.html 下载并安装 wkhtmltopdf 包
apt-get install xvfb libfontconfig
// 安装
dpkg -i wkhtmltox_0.12.6.1-2.jammy_amd64.deb

// 可能遇到缺少xfonts-75dpi
sudo apt-get install -y xfonts-75dpi
// 再次尝试安装 wkhtmltox 包
sudo dpkg -i wkhtmltox_0.12.6.1-2.jammy_amd64.deb

Python

常见问题

新版ubuntu使用pip时发生错误

error: externally-managed-environment
 
× This environment is externally managed
╰─> To install Python packages system-wide, try apt install
    python3-xyz, where xyz is the package you are trying to
    install.
    
    If you wish to install a non-Debian-packaged Python package,
    create a virtual environment using python3 -m venv path/to/venv.
    Then use path/to/venv/bin/python and path/to/venv/bin/pip. Make
    sure you have python3-full installed.
    
    If you wish to install a non-Debian packaged Python application,
    it may be easiest to use pipx install xyz, which will manage a
    virtual environment for you. Make sure you have pipx installed.
    
    See /usr/share/doc/python3.11/README.venv for more information.

解决方案：如果你习惯于原来的用法可以强制删除此警告

sudo mv /usr/lib/python3.x/EXTERNALLY-MANAGED /usr/lib/python3.x/EXTERNALLY-MANAGED.bak

安装时不能使用root权限

解决方案

安装yarn后如果再次出现找不到yarn的问题

molang@molang-System-Product-Name:~/workspace$ npm install -g yarn

found 0 vulnerabilitie
molang@molang-System-Product-Name:~/workspace$ yarn --version
找不到命令 “yarn”，但可以通过以下软件包安装它：
sudo apt install cmdtest
将yarn手动配置到Path环境变量中

找到yarn地址

molang@molang-System-Product-Name:~/workspace$ npm bin -g
/home/node/node-v18.12.1-linux-x64/bin

打开你的终端配置文件（通常是 **~/.bashrc**、**~/.bash_profile** 或 **~/.profile**），然后将 **yarn** 的安装路径添加到 PATH 变量中。

在文件的末尾添加以下行：

export PATH="$PATH:/home/node/node-v18.12.1-linux-x64/bin"

刷新配置

molang@molang-System-Product-Name:~/workspace$ source ~/.bashrc
molang@molang-System-Product-Name:~/workspace$ yarn --version

代理问题导致SOCKSp不可用最后就会显示ython -m pip install --quiet --upgrade -e 不可用

如果因为梯子导致pip intstall报错 ValueError: Unable to determine SOCKS version from socks://127.0.0.1:1080 问题

解决办法就是重置代理就ok

没有虚拟环境

molang@AY130628150444Z:~$ bench init frappe-erpnext
Setting Up Environment
$ python3 -m venv env
The virtual environment was not created successfully because ensurepip is not
available.  On Debian/Ubuntu systems, you need to install the python3-venv
package using the following command.

    apt install python3.10-venv

You may need to use sudo with that command.  After installing the python3-venv
package, recreate your virtual environment.

Failing command: /home/molang/frappe-erpnext/env/bin/python3

无法安装虚拟环境

root@AY130628150444Z:/home/molang#  apt install python3.10-venv
Reading package lists... Done
Building dependency tree... Done
Reading state information... Done
You might want to run 'apt --fix-broken install' to correct these.
The following packages have unmet dependencies:
 python3.10-venv : Depends: python3-pip-whl but it is not going to be installed
                   Depends: python3-setuptools-whl but it is not going to be installed
 wkhtmltox : Depends: fontconfig but it is not going to be installed
             Depends: libxrender1 but it is not going to be installed
             Depends: xfonts-75dpi but it is not going to be installed
E: Unmet dependencies. Try 'apt --fix-broken install' with no packages (or specify a solution).

看起来你遇到了依赖问题，导致无法安装 **python3.10-venv** 包。这可能是因为某些依赖包没有正确安装或者版本不兼容所致。

你可以尝试运行 **apt --fix-broken install** 命令来修复未满足的依赖关系，它会尝试自动解决依赖问题。

apt --fix-broken install

运行这个命令后，系统会尝试自动安装缺失的依赖项，并解决任何存在的依赖关系问题。

一旦修复了依赖关系问题，你就可以再次尝试安装 **python3.10-venv** 包。

apt install python3.10-venv

如果问题仍然存在，可能需要更深入地检查依赖关系，确保所有的依赖项都正确安装并且与系统兼容。

解决

bench init --skip-redis-config-generation frappe-bench

注意：在工作台初始化期间使用选项“–skip-redis-config- Generation”，不再需要这些操作。但至少，看看 ProcFile 看看在启动命令上启动 honcho 时发生了什么

Honcho 是 Bench 用来管理 Frappe 所需的所有流程的工具。通常，这些都在本地主机中运行，但在这种情况下，我们有 Redis 的外部容器。因此，我们必须阻止 Honcho 尝试启动 Redis 进程。

All git commands will error until this is rectified.

This initial message can be silenced or aggravated in the future by setting the
$GIT_PYTHON_REFRESH environment variable. Use one of the following values:
    - quiet|q|silence|s|silent|none|n|0: for no message or exception

没有虚拟环境

Setting Up Environment
$ python3 -m venv env
The virtual environment was not created successfully because ensurepip is not
available.  On Debian/Ubuntu systems, you need to install the python3-venv
package using the following command.

    apt install python3.10-venv

You may need to use sudo with that command.  After installing the python3-venv
package, recreate your virtual environment.

Failing command: /opt/frappe-erpnext/env/bin/python3
