# 问题
有需求,需要维护一个相对老的 Vue 项目,拿到项目之后,自然是先安装一下依赖,执行了 npm install
之后,看到了如下报错信息:

如上报错分两个点,一个是 python 命令依赖 python2,一个是 node-saas 下载路径为 404。
网上搜索的解决方案一大堆,不过大多数都是没有效果的。
这里记录两种解决方案,针对于这个问题。
# 方案一
我用的电脑是 Mac 的 M1 版本,系统里边默认的 Python 是 v3 的版本,所以如上错误是一个随着时间推移而产生的一个问题。
可以通过如下方式安装 Python 的 v2 来解决这个问题:
brew install pyenv
pyenv install 2.7.18
pyenv global 2.7.18
1
2
3

3
将环境变量放入系统配置文件:
$ cat ~/.zshrc | grep pyenv
export PATH="$HOME/.pyenv/shims:$PATH"

2
然后执行命令验证一下环境:
$ python
Python 2.7.18 (default, Jan 1 2024, 10:21:04)
[GCC Apple LLVM 14.0.0 (clang-1400.0.29.201)] on darwin
Type "help", "copyright", "credits" or "license" for more information.

看到版本为 v2 之后,再次回到项目中,执行 npm install
,发现就能成功安装依赖了。
有一个小的注意点是,你需要确保 npm 安装时默认使用的是 python,而非其他路径,可通过 npm config list
查看,当然,如果你的 python 需要指向其他的,那么单独安装依赖的时候,可以通过如下命令指定当次的 python:
npm install --python=python2.7
1
也可通过如下命令设置默认的 python 版本:
npm config set python python

# 方案二
从 node-sass 的角度来解决这个问题,在 node-sass 的 release 中可以看到,其并没有构建 arm 架构的二进制包,所以总是会构建失败。
但有一个方案是可以通过 sass 来替代 node-sass。
执行如下命令:
#卸载掉node-sass
npm uninstall node-sass
#安装sass
npm install sass

然后再次执行 npm install
就能成功安装依赖了。
只不过这种方案,会改变 package.json,目前还不知道会不会带来其他未可知的影响。
最后略微想吐槽一句,node 的依赖管理实在是弱。
