在OS X上使用nvm重新安装节点而不删除node_modules？ [英] Reinstall node using nvm on OS X without removing node_modules?
问题描述
按照最新建议，我决定删除以前可以正常工作的Homebrew节点安装并使用 nvm改为安装节点，并进行设置以避免使用sudo。
Following the latest advice I decided to remove a previous working Homebrew node install and use nvm to install node instead, and also set things up to avoid using sudo.
但是，在进一步操作之前
However, before going further
我仔细清理了以下文件夹（由我的用户拥有），除了两个模块用于长期使用旧版本节点的Ember项目（因为我没有有信心在以后重新安装所需的版本）：
I carefully cleaned out the following folder (owned by my user) except for two modules used for a long-standing Ember project that uses an older version of node (because I'm not confident of reinstalling the required version of them later):
/usr/local/lib/node_modules/
bower
ember-cli
如果我保留现有的/ usr / local / lib / node_modules /文件夹使用bower和ember-cli的版本，这会在安装nvm以及节点版本时引起任何问题我需要吗？
If I keep the existing /usr/local/lib/node_modules/ folder with the versions of bower and ember-cli, will this cause any issue on installing nvm and then the node versions I need?
推荐答案
NVM使用单独的node_modules文件夹
对话在这里对我自己说，但是在让问题开放15个多小时之后，我才继续（并遵循GitHub上的nvm指南）安装了带有curl的nvm ，最新的长期支持（LTS）节点带有 nvm install --lts
NVM uses separate node_modules folder
Talking to myself here, but after leaving the question open for 15+ hours I just went ahead and (following the nvm guide on GitHub) installed nvm with curl, the latest Long Term Support (LTS) node with nvm install --lts
以前，我使用 n来管理节点版本，但是NVM将node_modules存储在一个目录中，该目录由您当前正在使用的节点的版本确定，您可以在 npm root -g 中找到该目录，例如〜/ .nvm / versions / node / v10.15.3 / lib / node_modules
Previously, I was using n to manage node versions, but NVM stores node_modules in a directory determined by the version of node you're currently using, which you can find with npm root -g e.g. ~/.nvm/versions/node/v10.15.3/lib/node_modules
因此， n在 / usr / local / lib / node_modules / 中使用的先前的node_modules文件夹未被nvm使用，可以删除。在彻底清除并
strong>重新安装存储在其中的以前的节点模块。
So, the previous node_modules folder used by n at /usr/local/lib/node_modules/ is unused by nvm and can be deleted. After a thorough clean-out and brew uninstall of all the previous node installation there were no issues with new nvm install, and I now have to reinstall the previous node modules stored there.
