一、node运行环境
1、npm install -g n
通过npm 全局安装node
2、 sudo n 8.16.0
设置node版本
Password:
install : node-v8.16.0
mkdir : /usr/local/n/versions/node/8.16.0
fetch :
https://nodejs.org/dist/v8.16.0/node-v8.16.0-darwin-x64.tar.gz ######################################################################## 100.0%
installed : v8.16.0
3、node -v
v8.16.0
二、安装mongodb
1、brew tap mongodb/brew
2、brew install mongodb-community
=> Installing mongodb-community from mongodb/brew
==> Downloading
https://fastdl.mongodb.org/osx/mongodb-macos-x86_64-4.2.5.tgz ######################################################################## 100.0%
==> Caveats
To have launchd start mongodb/brew/mongodb-community now and restart at login:
brew services start mongodb/brew/mongodb-community
Or, if you don't want/need a background service you can just run:
mongod --config /usr/local/etc/mongod.conf
==> Summary
🍺 /usr/local/Cellar/mongodb-community/4.2.5: 21 files, 305.9MB, built in 7 minutes 4 seconds
(base) mengfaniaodeMBP:homebrew-core mengfanxiao$ cat usr/local/etc/mongod.conf
cat: usr/local/etc/mongod.conf: No such file or directory
(base) mengfaniaodeMBP:homebrew-core mengfanxiao$ brew services start mongodb/brew/mongodb-community
==> Successfully started `mongodb-community` (label: homebrew.mxcl.mongodb-community)
3、启动/停止
brew services start mongodb-community
brew services stop mongodb-community
4、配置
配置文件：/usr/local/etc/mongod.conf
日志目录路径：/usr/local/var/log/mongodb
数据目录路径：/usr/local/var/mongodb
5、端口
三、问题梳理
1、环境问题
node -v
dyld: Library not loaded: /usr/local/opt/icu4c/lib/libicui18n.64.dylib
Referenced from: /usr/local/bin/node
Reason: image not found
Abort trap: 6
说明node相关库已被损坏 需要重新安装
卸载node
brew uninstall --ignore-dependencies node icu4c
Uninstalling /usr/local/Cellar/node/13.5.0... (4,663 files, 59.1MB)
node 12.12.0 is still installed.
Run `brew uninstall --force node` to remove all versions.
安装node
brew install node
通过这种方式安装的是最新版本的node 但很容易出现版本不兼容问题 所以不推荐这么安装 建议安装node8 该版本比较稳定 很少出现与其他软件不兼容情况
2、文件创建权限问题
==> Installing dependencies for node: icu4c
==> Installing node dependency: icu4c
==> Downloading
https://mirrors.aliyun.com/homebrew/homebrew-bottles/bottles/icu4c-64.2.mojave.bottle.tar.gz ######################################################################## 100.0%
==> Pouring icu4c-64.2.mojave.bottle.tar.gz
Error: Failed to create /usr/local/opt/icu4c
Things that depend on icu4c will probably not build.
Could not symlink .
/usr/local/opt is not writable.
==> Caveats
a、创建文件夹
sudo mkdir /usr/local/opt
b、root用户赋予当前用户操作该文件夹权限
此时该文件夹权限属于root 给mengfanxiao账户赋予权限
chown -R mengfanxiao /usr/local/opt
3、插曲 springboot启动问题
dea启动spring-boot,报java.lang.NoClassDefFoundError: javax/servlet/ServletContext错误
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-tomcat</artifactId>
<scope>provided</scope>
</dependency>
把scope注释掉即可
maven中三种classpath
编译，测试，运行
1.compile： 默认范围 ，编译测试运行都有效
2.provided：在编译和测试时有效
3.runtime：在测试和运行时有效
4.test:只在测试时有效
5.system:在编译和测试时有效，与本机系统关联，可移植性差
4、环境不匹配问题
Node Sass does not yet support your current environment: OS X 64-bit with Unsupported runtime (79)qi
卸载重装（最新版本的node-sass）即可：
npm uninstall node-sass -D
npm install node-sass -D
5、版本冲突问题 node和mongodb版本不兼容
[email protected] requires a peer of kerberos@~0.0
node -v v13.12.0
npm -v 6.14.4
gyp ERR! command "/usr/local/Cellar/node/13.12.0/bin/node" "/usr/local/lib/node_modules/npm/node_modules/node-gyp/bin/node-gyp.js" "rebuild" gyp ERR! cwd /Users/mengfanxiao/Documents/project/company/wechain/questionnaire/node_modules/leveldown
gyp ERR! node -v v13.12.0
gyp ERR! node-gyp -v v5.1.0
gyp ERR! not ok
npm WARN
[email protected] requires a peer of kerberos@~0.0 but none is installed. You must install peer dependencies yourself.
这种情况需要安装node8
brew search node
==> Formulae
libbitcoin-node node node-sass node@12 nodebrew nodenv
llnode node-build node@10 node_exporter ✔ nodeenv
如果有node8
则 brew install node@8
然后brew link --overwrite --force node@8
没有node8
npm install -g n
sudo n 8.16.0
安装了node8版本
npm install
>
[email protected] install /Users/mengfanxiao/Documents/project/company/wechain/new/questionnaire/node_modules/level/node_modules/leveldown
> prebuild-install || node-gyp rebuild
added 42 packages from 44 contributors in 20.79s
6、安装mongodb问题
brew install mongodb
Error: No available formula with the name 'mongodb'
MongoDB不再是开源的了，并且已经从Homebrew中移除 #43770
安装MongoDB社区服务器的最新可用生产版本（包括所有命令行工具）。这将安装MongoDB 4.2.x：
$ brew install mongodb-community
安装MongoDB社区服务器和命令行工具的最新4.2.x生产版本：
$ brew install
[email protected] 安装MongoDB社区服务器和命令行工具的最新4.0.x生产版本：
$ brew install
[email protected] 安装MongoDB社区服务器和命令行工具的最新3.6.x生产版本：
$ brew install
[email protected] 仅安装最新的mongoshell以连接到远程MongoDB实例：
$ brew install mongodb-community-shell
