错误：EACCES：权限被拒绝，打开“/root/.config/truffle/config.json”

Question

无法更正尝试安装松露的 EACCESS 问题。

是的，我最初是通过 sudo 而不是 nvm 安装了 npm，但这已得到纠正 - 除非谁知道 - 根据网络。

这条路径实际上并不存在，所以我根据一个 git 问题创建了它：

/root/.config/truffle/

[root@home config]# ls -la |grep truffle
drwxrwxr-x. 2 root root   6 Jul 14 17:08 truffle

[user@home ~]$ nvm --version
0.34.0

$ npm -v
6.9.0

分配完全权限node_modules：

ll|grep node
drwxrwxrwx. 31 user user 4096 Jul 14 16:58 node_modules

我尝试了此链接中的建议：安装 npm 模块时权限被拒绝。

Ethereum SE 的用户在 Ubuntu问题上有这个问题。

浏览以下链接并授予 package-lock 的完全权限，以防问题npm 通知创建了一个锁文件为 package-lock.json。你应该提交这个文件

尝试强制清除 npm 缓存。

这个 github 用户显然通过在 V5 w/Linux 上使用sudo： truffle compile error (EACCES: permission denied)解决了这个问题#1212

也尝试以 root 身份安装。

$ sudo npm install -g truffle

Answer 1

我不仅遇到了松露问题，还遇到了其他模块的问题。对我来说，至少该线程中列出的其他解决方案有效，但它们的副作用是我只能以超级用户身份运行 truffle。我知道这可能有点鲁莽，但我的解决方案是将 .config 目录中所有文件的所有权更改为我的用户。为此，我执行了以下操作：

sudo chown myUsername:myUsername -R ~/.config

如果您想对此更加小心，您可以选择运行

sudo chown myUsername:myUsername ~/.config

sudo chown myUsername:myUsername ~/.config/truffle

sudo chown myUsername:myUsername ~/.config/truffle/config.json

完成此操作后，我能够运行sudo npm i -g truffle. 这是我以前遇到的所有问题的快速解决方案，希望它对您有用！

通过 nvm 将节点升级到版本 v12.6.0，关闭并今天早上回来并安装了 truffle：

[user@home ~]$ npm install truffle

> truffle@5.0.27 postinstall /home/user/node_modules/truffle
> node ./scripts/postinstall.js
