windows安装robotjs的心路

使用npm安装robotjs所遇到的问题

问题

通过命令npm install robotjs --save进行安装，遇到第一个待解决问题

搜索结果:

结果一：npm install --global --production windows-build-tools
结果二：手动安装python2.7版本，配置环境变量

二者本质上应该就是安装python，并配置环境变量
但 结果一 会一直卡死在 python 安装成功上
具体原因不详

继续入坑

1. 手动安装python成功
2. 先使用npm cache clean -f命令清理npm缓存，尽量排除掉干扰
3. 再次使用npm install robotjs --save进行安装，至此遇到第二个问题

经过搜索以及提示排查
大致问题是ascii的编码问题
找到提示的第一个文件File "C:\dev\nvm\v14.13.1\node_modules\npm\node_modules\node-gyp\gyp\gyp_main.py", line 50, in <module>

出坑

在找到的文件中修改如下

import os
import sys
import subprocess

# 添加代码
# 由于windows默认是使用的gbk字符集
# 故此将字符集修改为gbk
defaultencoding = 'gbk'
if sys.getdefaultencoding() != defaultencoding:
    reload(sys)
    sys.setdefaultencoding(defaultencoding)
# 结束添加代码

PY3 = bytes != str

# Below IsCygwin() function copied from pylib/gyp/common.py
def IsCygwin():
  try:
    out = subprocess.Popen("uname",
            stdout=subprocess.PIPE,
            stderr=subprocess.STDOUT)
    stdout, stderr = out.communicate()
    if PY3:
      stdout = stdout.decode("utf-8")
    return "CYGWIN" in str(stdout)
  except Exception:
    return False

成功

再次使用npm install robotjs --save进行安装
输出如下：

再遇问题

1. robotjs安装成功后，还需要进行编译的一个过程
2. 先使用npm install electron-rebuild --save-dev命令安装编译所需的electron-rebuild包
3. 使用npx electron-rebuild进行编译，然而问题又一次的出现了

4. 使用命令npx electron-rebuild -d=https://npm.taobao.org/mirrors/atom-shell尝试使用淘宝镜像进行解决，but 依然报错，而且似乎更严重
5. 根据关键字gyp WARN install got an error, rolling back install进行搜索
6. 结果：需要设置（临时的）环境变量，以使得其能重定向

详情参见：https://blog.csdn.net/u013613428/article/details/51545479
由此去

7. 使用set ATOM_NODE_URL=http://gh-contractor-zcbenz.s3.amazonaws.com/atom-shell/dist进行设置环境变量，完成其重定向
8. 再使用npx electron-rebuild命令进行编译，but又有问题，但一看便知与上面的字符编码是同一个问题，故此便不再赘述
