之前有时报这个，以为还真是权限不够，感觉有点奇怪，用管理员权限执行，有时还真有用，不过后面查了下，时缓存的问题，清理下缓存就行，不用管理员权限。

方法1、

需要删除npmrc文件。

强调：不是nodejs安装目录npm模块下的那个npmrc文件

而是在C:\Users\{账户}\下的.npmrc文件..

方法2、

或者直接用命令清理就行，控制台输入：

npm cache clean --force

E:\SouthernPowerGridProject\web_project\AutoOPS\autoops>npm cache clean --force
npm WARN using --force I sure hope you know what you are doing.

激活osd时（ceph-deploy osd activate node1:/dev/sdm1）报错

》1.

[root@node2 ceph-cluster]# ceph auth get client.bootstrap-osd --name mon. --keyring /var/lib/ceph/mon/ceph-node2/keyring
exported keyring for client.bootstrap-osd
[client.bootstrap-osd]
        key = AQAnVp1dBC6mKhAAzw0817xQOHZhnz0jPzwxEQ==

2、修改对应server上的/var/lib/ceph/bootstrap-osd/ceph.keyring文件为上面查到的内容

3、重新激活osd

Could not install packages due to an Environment Error: [Errno 13] Permission denied 解决方案

执行 pip install 报错如下：

Could not install packages due to an Environment Error: [Errno 13] Permission denied: ''/usr/local/lib/python3.5/dist-packages/kiwisolver.cpython-35m-x86_64-linux-gnu.so'' Consider using the `--user` option or check the permissions.

解决方案：

Linux / macOS

From your terminal, you can install the package for your user only, like this:

pip install <package> --user

OR

You can use su or sudo from your terminal, to install the package as root:

sudo pip install <package>

Windows

From the Command Prompt, you can install the package for your user only, like this:

pip install <package> --user

OR

You can install the package as Administrator, by following these steps:

1. Right click on the Command Prompt icon.
2. Select the option Run This Program As An Administrator.
3. Run the command pip install <package>

docker strace ptrace 报错 Operation not permitted 解决方法

docker中gdb在进行进程debug时，会报错：

(gdb) attach 30721
Attaching to process 30721

ptrace: Operation not permitted.

原因就是因为ptrace被Docker默认禁止的问题。考虑到应用分析的需要，可以有以下几种方法解决：

1、关闭seccomp

docker run --security-opt seccomp=unconfined 

2、采用超级权限模式

docker run --privileged

3、仅开放ptrace限制

docker run --cap-add sys_ptrace 

当然从安全角度考虑，如只是想使用gdb进行debug的话，建议使用第三种。

安全计算模式（secure computing mode，seccomp）是 Linux 内核功能，可以使用它来限制容器内可用的操作。

Docker 的默认 seccomp 配置文件是一个白名单，它指定了允许的调用。

下表列出了由于不在白名单而被有效阻止的重要（但不是全部）系统调用。该表包含每个系统调用被阻止的原因。
